XSLTProcessor::setParameter

(PHP 5, PHP 7)

XSLTProcessor::setParameterУстанавливает значение параметра

Описание

bool XSLTProcessor::setParameter ( string $namespace , string $name , string $value )
bool XSLTProcessor::setParameter ( string $namespace , array $options )

Устанавливает значение для одного или нескольких параметров, чтобы использовать в дальнейшем в преобразованиях XSLTProcessor. Если параметра нет в таблице стилей, то он будет проигнорирован.

Список параметров

namespace

Пространство имён URI параметра XSLT.

name

Локальное название параметра XSLT.

value

Новое значение параметра XSLT.

options

Массив пар name => value. Этот синтаксис доступен с PHP 5.1.0.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Примеры

Пример #1 Изменение владельца перед преобразованием

<?php

$collections 
= array(
    
'Marc Rutkowski' => 'marc',
    
'Olivier Parmentier' => 'olivier'
);

$xsl = new DOMDocument;
$xsl->load('collection.xsl');

// Настройка преобразования
$proc = new XSLTProcessor;
$proc->importStyleSheet($xsl); // добавление стилей xsl

foreach ($collections as $name => $file) {
    
// Load the XML source
    
$xml = new DOMDocument;
    
$xml->load('collection_' $file '.xml');

    
$proc->setParameter('''owner'$name);
    
$proc->transformToURI($xml'file:///tmp/' $file '.html');
}

?>

Example for how it works.

<?xml version '1.0' encoding 'utf-8' ?>

I've been trying to pass in a DOMDocument object as a parameter so I can stuff a bunch of data into XML nodes, but it appears that this function is not capable of it. I was hoping to get it to work like it does in the .NET 2.0 framework. (See http://msdn2.microsoft.com/en-us/library/
system.xml.xsl.xsltargumentlist.addparam.aspx)
But after looking at the PHP 5.2.1 source code, /php-5.2.1/ext/xsl/xsltprocessor.c line 604-650, it appears that it's not possible to do so in PHP even though it appears that libxslt supports it (see http://xmlsoft.org/XSLT/html/libxslt-variables.html
#xsltParseGlobalParam)

In fact, if the parameters aren't exactly what's expected, you'll always get a warning like this:

Wrong parameter count for XSLTProcessor::setParameter()

After looking at this a little further (see http://bugs.php.net/bug.php?id=41248), it appears that it's a shortcoming of libxslt, not PHP, that prevents passing in DOMDocuments or DOMNodes as parameters.

It seems heinemann's usage is not correct and does not achieve the intended result.

This method's purpose is to change a global <xsl:param> value in the XSL stylesheet--not to change an attribute of any other element.  <xsl:param> basically lets you set up a stylesheet which can be customized (as from PHP) externally (without needing to tamper with the original XSL file).

Here's an example of usage (that will work):

Stylesheet:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:param name="print_something" select="defaultstring"/>
    <xsl:template match="/mydoc">
        <p style="color:red;">Printed parameter: <xsl:value-of select="$print_something"/></p>
    </xsl:template>
</xsl:stylesheet>

Script: 

<?php
$dom 
= new DOMDocument();
$xsl = new XSLTProcessor;
$xsl->setParameter'''print_something'"Now I've overridden the default!");
$style realpath"./my_stylesheet.xslt" );
$dom->load($style);
$xsl->importStyleSheet($dom);
$dom->loadXML('<mydoc></mydoc>');

$out $xsl->transformToXML$dom );

var_dump'<pre>',
   
htmlentities$outENT_QUOTES'utf-8' ),
   
$xsl->getParameter('''print_something'),
'</pre>' );
?>

gives:

string(5) "

"
string(143) "<?xml version="1.0"?>
<p style="color:red;">Printed parameter: Now I've overridden the default!</p>
"
string(32) "Now I've overridden the default!"
string(6) "



Notice that at present adding a namespace will not work. The only option at present is to set the first parameter for namespace to an empty string (though you can add the prefix with colon to the second argument for name in order to set the parameter for a namespace-prefixed parameter name).

[EDIT by nielsdos: This is no longer true as of PHP 8.4.0]

The parameter will not be set if the value contains both single and double quotes. Instead a warning will be shown when transforming the document:

PHP Warning:  XSLTProcessor::transformToXml(): Cannot create XPath expression (string contains both quote and double-quotes)

Note that there is no way to remove a parameter from an XSLTProcessor unless you know its name, and there is no way (that I can find) to get a list of the current parameters.

This means that you cannot reuse an XSLTProcessor with different parameters unless you call XSLTProcessor->removeParameter() on every parameter, and to do that you need to know the names of all the currently set parameters.

I bumped into this because we were caching XSLTProcessors for reuse, and they were spitting out content based on phantom parameters (they were still there from previous uses).
