XSLT: Passing all attributes of a tag to a php function

I have written the following XSLT template:

<xsl:template match="foo:*">
    <开发者_高级运维;xsl:processing-instruction name="php">$s = ob_get_clean(); ob_start(); $this->callExtensionStartHandler('<xsl:value-of select="local-name()" />');</xsl:processing-instruction>
    <xsl:apply-templates/>
    <xsl:processing-instruction name="php">$sExtensionContent = ob_get_clean(); ob_start(); echo $s; echo $this->callExtensionEndHandler('<xsl:value-of select="local-name()" />', $sExtensionContent);</xsl:processing-instruction>
</xsl:template>

Now I want to pass all attributes and their values of the tag to the php function. If I had a template:

<foo:test id="a" bar="xzz"/>

I would like to have an array('id' => 'a', 'bar' => 'xzz') available in my php function. Is that possible. I don't want to restrict the names of the attributes, so there could be any attribute name.

I am not familiar with PHP, but this may be helpful:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:foo="foo:foo">
 <xsl:output method="text"/>

 <xsl:template match="foo:test">
  array(<xsl:apply-templates select="@*"/>)
 </xsl:template>

 <xsl:template match="foo:test/@*">
  <xsl:if test="not(position()=1)">, </xsl:if>
  <xsl:value-of select=
  'concat(&quot;&apos;&quot;,name(),&quot;&apos;&quot;,
          " => ",
          &quot;&apos;&quot;,.,&quot;&apos;&quot;)'/>
 </xsl:template>
</xsl:stylesheet>

When this transformation is applied on this XML document (the provided one, made well-formed):

<foo:test id="a" bar="xzz" xmlns:foo="foo:foo"/>

the wanted, correct result is produced:

  array('id' => 'a', 'bar' => 'xzz')

Update: In a comment the OP asked:

Thank you, that looks great! Is it possible to add an escaping to the attribute value? Every ' should become \'

Answer: Yes, we can get this output by slightly modifying the original solution:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:foo="foo:foo">
 <xsl:output method="text"/>

 <xsl:template match="foo:test">
  array(<xsl:apply-templates select="@*"/>)
 </xsl:template>

 <xsl:template match="foo:test/@*">
  <xsl:if test="not(position()=1)">, </xsl:if>
  <xsl:value-of select=
  'concat(&quot;\&quot;,&quot;&apos;&quot;,name(),&quot;\&quot;,&quot;&apos;&quot;,
          " => ",
          &quot;\&quot;,&quot;&apos;&quot;,.,&quot;\&quot;,&quot;&apos;&quot;)'/>
 </xsl:template>
</xsl:stylesheet>

When applied on the same XML document, this transformation produces:

  array(\'id\' => \'a\', \'bar\' => \'xzz\')

Can't you just pass the element itself and then get all the attributes with an appropriate php function? That way you don't need to care about names of the attributes since I am sure there is a way to iterate through all of the attributes of an element in php :)
