The transformToXML function can produce valid XHTML output - it honours the <xsl:output> element's attributes, which defines the format of the output document.

For instance, if you want valid XHTML 1.0 Strict output, you can provide the following attribute values for the <xsl:output> element in your XSL stylesheet:

<xsl:output
method="xml"
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd" 
doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN" />

The function transformToXML has a problem with the meta content type tag. It outputs it like this:

   <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

which is not correct X(HT)ML, because it closes with '>' instead of with '/>'.

A way to get the output correct is to use instead of transformToXML first transformToDoc anf then saveHTML:

   $domTranObj = $xslProcessor->transformToDoc($domXmlObj);
   $domHtmlText = $domTranObj->saveHTML();

transformToXML, if you have registered PHP functions previously, does indeed attempt to execute these functions when it finds them in a php:function() pseudo-XSL function. It even finds static functions within classes, for instance:

<xsl:value-of select="php:function('MyClass::MyFunction', string(@attr), string(.))" disable-output-escaping="yes"/>

However, in this situation transformToXML does not try to execute "MyClass::MyFunction()". Instead, it executes "myclass:myfunction()". In PHP, since classes and functions are (I think) case-insensitive, this causes no problems.

A problem arises when you are combining these features with the __autoload() feature. So, say I have MyClass.php which contains the MyFunction definition. Generally, if I call MyClass::MyFunction, PHP will pass "MyClass" to __autoload(), and __autoload() will open up "MyClass.php".

What we have just seen, however, means that transformToXML will pass "myclass" to __autoload(), not "MyClass", with the consequence that PHP will try to open "myclass.php", which doesn't exist, instead of "MyClass.php", which does. On case-insensitive operating systems, this is not significant, but on my RedHat server, it is--PHP will give a file not found error.

The only solution I have found is to edit the __autoload() function to look for class names which are used in my XSL files, and manually change them to the correct casing.

Another solution, obviously, is to use all-lowercase class and file names.
