For debug purposes i want to output the input xml document inside a textarea. This is a easy way to select and copy the xml and use later in other application.

So, here it is:

<xsl:stylesheet 
 version="1.0" 
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output 
 method="html" 
 encoding="ISO-8859-1" 
 indent="yes"
 omit-xml-declaration="yes"  
 media-type="text/html"/>
 
<xsl:template match="node()|@*">
 <xsl:copy>
  <xsl:apply-templates select="node()|@*"/>
 </xsl:copy> 
</xsl:template>
				
<xsl:template match="/">
 <textarea cols="80" rows="20">
  <xsl:apply-templates select="node()|@*"/>
 </textarea>
</xsl:template>
	
</xsl:stylesheet>

Hi all,

several days ago i’ve to use XSLT transformation in PHP code. One of the requirements is to use external .xml files, so in the .xsl file i have to use references like http://example.com/xml/myfile.xml, but sablotron doesn’t seems to implement this kind of schema. Only works with file: schema.

<xsl:value-of
select="document('http://example.com/xml/myfile.xml')
/items/group/item[./@code='ES']/@value"/>

this is a piece of XSLT that i want to use

I thought an update system that download the external resources, but, i can’t believe that didn’t exist any better solution (of course simpler).

My fist attemp was using xslt_base_dir with and url like:

$xh = xslt_create();
$fileBase = 'http://example.com/xml/';
xslt_set_base ( $xh, $fileBase );

… but didn’t work.

Checking all the XSLT methods in the PHP reference i’ve found one that seems fit: xslt_set_scheme_handlers. Despite it isn’t already documented one comment is enough explanatory.

function mySchemeHandler($processor, $scheme, $rest) {
 if($scheme == 'http') {
  return file_get_contents($scheme.":".$rest);
 }
}

$SchemeHandlerArray = array();
$SchemeHandlerArray["get_all"] = "mySchemeHandler";
			
$xh = xslt_create();
xslt_set_scheme_handlers($xh,$SchemeHandlerArray);
			
echo xslt_process($xh, 'arg:/_xml', $config['xslt'], NULL,
 array ( '/_xml' => utf8_encode($result) ), 
 array (	
  'link' => $link , 
  'locale' => $config['locale'] ,
  'extra' => $config['extra']
) );

xslt_free($xh);

and .. works!!
