xmlXPathCompOpEval & XPath errors

[phpbossman]

Hello, I recently moved hosts and upgraded to PHP 7.4.10. Suddenly, one of my sites is having issues with XSL views. The software creator claims this is an issue with XSL in PHP. I am unsure of what to check to troubleshoot this. Would anyone have an opinion on my issue? If not, please let me know if I should be posting somewhere else altogether. Thanks in advance -

xmlXPathCompOpEval: function function not found
XPath error : Unregistered function
xmlXPathCompiledEval: 3 objects left on the stack.
runtime error: file /Sitessection/view.xsl line 32 element value-of
XPath evaluation returned no result

The view.xsl file:

 

Quote

        <xsl:value-of select="php:function( 'SobiPro::AlternateLink', $rssUrl, 'application/atom+xml', $sectionName )"/>
        <xsl:variable name="showCategoriesLabel">
            <xsl:value-of select="php:function( 'SobiPro::Txt', 'CATEGORIES_SHOW' )"/>
        </xsl:variable>

"function function not found" suggests XSLT that looks like

select="php:function('function', ...)"

Are you sure you are looking at the right code?

[phpbossman]

Yes and I agree. It's

xmlXPathCompiledEval: 3 objects left on the stack.
runtime error: file /view.xsl line 32 element value-of
XPath evaluation returned no result.

 

Also get this in PHP but I believe irrelevant:

PHP Warning:  "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /view.php on line 1436

You agree that... you're looking at the wrong code?

Not to your original problem, but you should fix it anyways.

[phpbossman]

I said "yes" to I'm sure I'm looking at the right code.

I agree that I would think it should be something different, but those are the lines the error references in the file.

 

 

Thanks for confirming

Does the XSLT include

xmlns:php="http://php.net/xsl"

or does it use a namespace-alias?

Here is the full xls.

I don't know what's going on.

But I do know

<input type="hidden" id="hidetext" value="{php:function( 'SobiPro::Txt', 'CATEGORIES_HIDE' )}"/>

that won't work.
