# CLXXX. XSLT Functions

# Введение

This PHP extension provides a processor independent API to XSLT transformations. Currently this extension only supports the Sablotron library from the Ginger Alliance. Support is planned for other libraries, such as the Xalan library or the libxslt library.

XSLT (Extensible Stylesheet Language (XSL) Transformations) is a language for transforming XML documents into other XML documents. It is a standard defined by The World Wide Web Consortium (W3C). Information about XSLT and related technologies can be found at http://www.w3.org/TR/xslt.

> Замечание: This extension is different than the sablotron extension distributed with versions of PHP prior to PHP 4.1, currently only the new XSLT extension in PHP 4.1 is supported. If you need support for the old extension, please ask your questions on the PHP mailing lists.

> Замечание: This extension has been moved to the PECL repository and is no longer bundled with PHP as of PHP 5.0.0.

> Замечание: If you need xslt support with PHP 5 you can use the XSL extension.

# Требования

This extension uses Sablotron and expat, which can both be found at http://www.gingerall.org/sablotron.html. Binaries are provided as well as source.

# Установка

On Unix, run configure with the `--enable-xslt` `--with-xslt-sablot` options. The Sablotron library should be installed somewhere your compiler can find it.

Make sure you have the same libraries linked to the Sablotron library as those, which are linked with PHP. The configuration options: `--with-expat-dir=DIR` `--with-iconv-dir=DIR` are there to help you specify them. When asking for support, always mention these directives, and whether there are other versions of those libraries installed on your system somewhere. Naturally, provide all the version numbers.

Предостережение
Be sure your Sablot library is linked to `-lstdc++` as otherwise your configure will fail, or PHP will fail to run or load.

> JavaScript E-XSLT support: If you compiled Sablotron with JavaScript support, you must specify the option: `--with-sablot-js=DIR`.

> Note to Win32 Users: In order to enable this module on a Windows environment, you must copy several files from the DLL folder of the PHP/Win32 binary package to the SYSTEM32 folder of your windows machine. (Ex: `C:\WINNT\SYSTEM32` or `C:\WINDOWS\SYSTEM32`). For PHP <= 4.2.0 copy `sablot.dll` and `expat.dll` to your SYSTEM32 folder. For PHP >= 4.2.1 copy `sablot.dll`, `expat.dll` and `iconv.dll` to your SYSTEM32 folder.

# Настройка во время выполнения

Данное расширение не определяет никакие директивы конфигурации в `php.ini`.

# Типы ресурсов

Данное расширение не определяет никакие типы ресурсов.

# Предопределенные константы

Перечисленные ниже константы определены данным расширением и могут быть доступны только в том случае, если PHP был собран с поддержкой этого расширения или же в том случае, если данное расширение подгружается во время выполнения.

`XSLT_OPT_SILENT` (integer)

  Drop all logging and error reporting. This is a generic option for all backends that may be added in the future.

`XSLT_SABOPT_PARSE_PUBLIC_ENTITIES` (integer)

  Tell Sablotron to parse public entities. By default this has been turned off.

`XSLT_SABOPT_DISABLE_ADDING_META` (integer)

  Do not add the meta tag "Content-Type" for HTML output. The default is set during compilation of Sablotron.

`XSLT_SABOPT_DISABLE_STRIPPING` (integer)

  Suppress the whitespace stripping (on data files only).

`XSLT_SABOPT_IGNORE_DOC_NOT_FOUND` (integer)

  Consider unresolved documents (the document() function) non-lethal.

`XSLT_SABOPT_FILES_TO_HANDLER` (integer)

`XSLT_ERR_UNSUPPORTED_SCHEME` (integer)

  Error return code, for scheme handlers.

`I believe the xslt_process and its URI resolving behaviour, including the xslt_set_base function are violating the XSLT specification which states:
<blockquote>
3.2 Base URI
Every node also has an associated URI called its base URI, which is used for resolving attribute values that represent relative URIs into absolute URIs. If an element or processing instruction occurs in an external entity, the base URI of that element or processing instruction is the URI of the external entity; otherwise, the base URI is the base URI of the document. The base URI of the document node is the URI of the document entity. The base URI for a text node, a comment node, an attribute node or a namespace node is the base URI of the parent of the node.
</blockquote>
This implies that if stylesheet file A contains a <xsl:import href="../B.xsl" /> and stylesheet file B contains a <xsl:import href="../C.xsl" />, given that all physical paths are valid, no matter which base you set up for the XSLT extension (with xslt_set_base) the processor WILL FAIL. Simply because it uses a single base path for all its processing regardless of the context (importing file) which includes/imports. This is a violation of the above part of the specification quoted above.
And it makes it very difficult to program XSLT with PHP.`

`bat at flurf, you said that Sablotron implements XSLT 1.1, but according to its makers, "Sablotron is ...implementing XSLT 1.0, DOM Level2 and XPath 1.0" [http://www.gingerall.org/sablotron.html]`
bat at flurf dot net

`maurits says that libxslt should be preferred over Sablotron, but I disagree. libxslt only implements a fraction of the capabilities of Sablotron; in particular, this doesn't work in libxslt:
<xsl:variable name="x">
<a>One</a>
<a>Two</a>
<a>Three</a>
</xsl:variable>
<xsl:for-each select="$x/a">
<xsl:value-of select="."/>
</xsl:for-each>
In Sablotron, which implements XSLT 1.1, this works fine. In libxslt's version, XSLT 1.0, a variable is a "result tree fragment", not a nodeset, and you are arbitrarily not allowed to do as much with it.
Further, Sablotron allows callbacks via the document() function (see information on xslt_set_scheme_handler()) and appears to give /slightly/ more informative error messages -- they identify the line number in the XSLT file at least.
In general, I can't recommend libxslt, which appears very underpowered. Sablotron is considerably more impressive.`

`If you need to transform an XML document that specifies the URL of its own prefered stylesheet (using the processing instruction <?xml-stylesheet href="xyz.xsl"?>, you can start by parsing the XML data to retrieve that URL, and then call the xslt_process function using the specified stylesheet :
<?php
/* A small class for stylesheet URL extraction from an XML */
class XMLStylesheet
{
var $hParser;
var $xml;
var $stylesheet;
function XMLStylesheet($filename)
{
$this->hParser = xml_parser_create();
xml_set_object($this->hParser, $this);
xml_set_processing_instruction_handler($this->hParser, 'fnProcessingInstruction');
$this->xml = file_get_contents($filename);
xml_parse($this->hParser, $this->xml, true);
xml_parser_free($this->hParser);
}
function getStylesheet()
{
return $this->stylesheet;
}
function fnProcessingInstruction($hParser, $target, $data)
{
if($target == 'xml-stylesheet')
{
ereg('href="([^"]+)"', $data, $regs);
$this->stylesheet = $regs[1];
}
}
}
/* Now, instanciate an object of this class, given the filename of our XML data */
$xml = new XMLStylesheet('my_data.xml');
/* And finally, retrieve the URL of the stylesheet specified in the XML data. */
$xsl_url = $xml->getStylesheet());
/* Now you can xslt_process as usual. */

`I tried to get Sablotron runnning on a Windows XP - Apache 2 -PHP5 System which is my developement system. I have Sablotron running on a life Linux server. After spending lots of effort I gave up on Sablotron on Windows.
Then I found out that there is Libxslt, and it is allready working!
I am missing a hint on this page, that Sablotron is not really recommended any more and that people should start to migrate their code to Libxslt.`

`Getting XSLT running under Red Hat/Plesk 7.5
The PHP installation on my VPS came with '--enable-xslt=shared' '--with-xslt-sablot' '--with-sablot-js=/usr' in the config line. However could not get any transformations to run. Finally got there following these steps:
1. ran 'yum install php-xslt'
2. This installed 'xslt.so' to usr/lib/php4 and other dependencies.
3. Add 'dl('xslt.so');' to the top of your php files you want to perform a translation in. e.g.
dl('xslt.so');
// Allocate a new XSLT processor
$xh = xslt_create();
// Process the document, returning the result into the $result variable
$result = xslt_process($xh, 'test.xml', 'test.xsl');
// Output to browser
echo $result;`

Just make sure you emerged the expat and sablotron packages like so:

`In reply to Jaron, who needed to evaluate PHP code inside the stylesheet, look at a post I sent about xslt_set_scheme_handlers().
Scheme handlers are very useful, since they allow the XSLT engine and PHP to fully interact (they will communicate through XML strings).
With xslt_set_scheme_handlers(), you can give the XSLT engine an advanced access to the file system (or even to the other I/O interfaces), and perform various tasks (checking the existence of a file, creating new files "on the fly", deleting, etc...)
... all that in only one stylesheet :)

`The XSLT functions may experience conflicts with Apache in some configurations, causing random segfaults in httpd. Apache has included a 'lite' version of expat in their recent distributions, which can cause conflicts with expat. Apache1.3.22 solves the problem by configuring itself to use the expat you have installed, instead of the built-in. If you compiled Apache before you installed expat, make sure you upgrade and/or recompile your Apache server with the same version of expat that PHP and Sablotron are using.`

`I extended the example of Daniel Unterberger even more. I had the problem to evaluate PHP code within my xml data files (e.g. to output database results) and after that apply a xsl stylesheet to the generated data.
When I tried Daniel's solution I found it quite useful but noticed that you can't "print out" from your PHP Code. You're bound to annoying return()-Statements, wich makes it impossible to loop outputs or concatenate strings and then return them. If you try to do so, you will notice that a statement like
...
<php:eval>
for($i=0; $i<10; $i++)
echo "This is number ".$i;
</php:eval>
...
will result in PHP to do the output right in the moment when the eval()-Statement is run.
Things do, at least, work fine if you keep it simple:
...
<php:eval>
return("Hello World!");
</php:eval>
...
I tried to fix that and came to a solution. The following code is just a snippet from my XSLT-class. The uppercase letters are constants defined in a header file. (e.g. define('PHP_EVAL_START_TAG', '<php:eval>');
...
function xmlString() {
$fd = fopen($this->xmlFileLocation, 'r');
$xmlString = fread($fd, filesize($this->xmlFileLocation));
fclose($fd);
if($this->contentType == DYNAMIC_CONTENT) {
while(!(strpos($xmlString, PHP_EVAL_START_TAG) === false)) {
$startPos = strpos($xmlString, PHP_EVAL_START_TAG);
$endPos = strpos($xmlString, PHP_EVAL_END_TAG);
ob_start();
eval(substr($xmlString, $startPos + strlen(PHP_EVAL_START_TAG), $endPos - $startPos - strlen(PHP_EVAL_START_TAG)));
$evaluatedString = ob_get_contents();
ob_end_clean();
$xmlString =
substr($xmlString, 0, $startPos).$evaluatedString.substr($xmlString, $endPos + 11);

`[Editor's note: moved this note here where it belongs - jmcastagnetto@php.net]
This shows how you can use the XSLT functions to add dynamic content to the result tree, i.e. how to hand over parameters to the XSL stylesheet and write to Sablotron's document buffer.
First we assign the value of the parameter to an array in PHP:
-----------------------------------------
$xslt_params["test"] = "Run-time parameter.";
-----------------------------------------
The parameter is envoced in XSL by
-----------------------------------------
<h1>Value of run-time parameter:</h1>
<b><xsl:value-of select="$test" /></b>
<hr/>
-----------------------------------------
Don't forget to define the parameter at the beginning of your stylesheet:
-----------------------------------------
<xsl:param name="test"/>
-----------------------------------------
How can we add dynamic content from a database to the XSLT output? In Sablotron, this is done using the document buffer function.
Retrieve a table's content, store it in a XML structure assigned to an array in PHP:
-----------------------------------------
$xslt_args["buffer1"] =
"
<TestBuffer>
<Message>
<Content>
This is message 1 of buffer 1.
</Content>
</Message>
<Message>
<Content>
This is message 2 of buffer 1.
</Content>
</Message>
</TestBuffer>
";
-----------------------------------------
This is how you add the buffer to the result tree in your XSL document:
-----------------------------------------
<h1>Dynamic content from document buffer 1:</h1>
<xsl:for-each select="document('arg:/buffer1')/TestBuffer/Message">
<b><xsl:value-of select="Content" /></b><br/>
</xsl:for-each>
<hr/>
-----------------------------------------
To get the whole thing running, following functions have to be executed:
-----------------------------------------
$processor = xslt_create();
xslt_run ($processor, "file://".$DOCUMENT_ROOT.$xsl_file, "file://".$DOCUMENT_ROOT.$xml_file, "arg:/_result", $xslt_params, $xslt_args);
$result = xslt_fetch_result ($processor);
echo $result;
-----------------------------------------
The complete XSL file looks like this:
-----------------------------------------
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="html" version="1.0" standalone="yes" indent="yes" />
<!-- define parameter -->
<xsl:param name="test"/>
<xsl:template match="/">
<!-- run-time parameter -->
<h1>Value of run-time parameter:</h1>
<b><xsl:value-of select="$test" /></b>
<hr/>
<!-- dynamic content -->
<h1>Dynamic content from document buffer 1:</h1>
<xsl:for-each select="document('arg:/buffer1')/TestBuffer/Message">
<b><xsl:value-of select="Content" /></b><br/>
</xsl:for-each>
<hr/>
</xsl:template>
</xsl:stylesheet>

`COMPILING AND INSTALLING SABLOTRON AND EXPAT FOR PHP ON A FREEBSD iServer
0) Prepare your virtual server environment. Telnet to your iserver and type:
mkdir -p ~/usr/local/apache/1.3/bin
ln /usr/bin/make ~/usr/bin/make
ln /usr/local/apache/1.3/bin/apxs ~/usr/local/apache/1.3/bin/apxs
ln /usr/local/apache/1.3/bin/httpd ~/usr/local/apache/1.3/bin/httpd
1) download the following files:
expat-1.95.tar.gz - http://expat.sourceforge.com
Sablot-0.52.tar.gz - http://www.gingerall.com
php4-latest.tar.gz - http://snaps.php.net
2) copy these files to ~/usr/local
3) expand all these files uing tar -xvzf
4) go into expat directory and type:
./configure --prefix=/usr/home/your_iserver_login_name/usr/local
make
make install
the files will be installed under ~/usr/local/lib and ~/usr/local/include
5) set the following environment variables:
setenv LD_LIBRARY_PATH /usr/home/your_iserver_login_name/usr/local/lib
setenv LD_RUN_PATH /usr/home/your_iserver_login_name/usr/local/
setenv CPLUS_INCLUDE_PATH /usr/home/your_iserver_login_name/usr/local/include
setenv LIBRARY_PATH /usr/home/your_iserver_login_name/usr/local/lib
6) go into the Sablotron directory and type:
./configure --prefix=/usr/home/your_iserver_login_name/usr/local
make
make install
7) go into the php directory and type:
./configure --with-apxs=/usr/local/apache/1.3/bin/apxs \
--disable-debug \
--enable-trans-sid \
--enable-versioning \
--enable-ftp \
--with-mysql=/usr/home/your_iserver_login_name/usr/local/mysql \
--with-xml \
--enable-magic-quotes \
--enable-track-vars \
--enable-sablot-errors-descriptive \
--with-sablot=/usr/home/your_iserver_login_name/usr/local \
--with-expat=/usr/home/your_iserver_login_name/usr/local
then
make
and
make install
the final command - make install - should give an error about not being able to install pear.
This is normal, as pear tries to copy itself outside of your virtual server space. Since pear
is not an essential part of PHP - you can ignore this. (maybe there is a command for ./configure
in php that allows us to specify the directory in which pear will be installed?
8) final steps:
go to ~/usr/local/etc/httpd/conf
edit httpd.conf
comment out the LoadModule directive for the previous php .so module.
not that you should see the new module you just compile already inserted in the httpd.conf as
the last line of all LoadModule directives. (it should be called libphp4.so
now just go back to the command prompt after you have edited httpd.conf and type:
restart_apache
now go to your httpd document root (usually htdocs), and create a php file with the following
code in it:
<?php
phpinfo();
?>
load the file in your browser, and you should see that everything has been installed properly :)`
