Hello, are XSLT functions supported in lxml (I am now using 4.1 lxml)? For example I have: And then use it in "select" statements in temaplates. When I use my function in the select statement, I get "XSLTParseError: Invalid expression" - so I suspect that this feature is not supported in lxml. Regards, remek

Hi,

And then use it in "select" statements in temaplates.

When I use my function in the select statement, I get "XSLTParseError: Invalid expression" - so I suspect that this feature is not supported in lxml.

If I remember correctly xslt functions are an XSLT 2 feature. lxml supports XSLT 1 only, through libxml2/libxslt. However, exslt extensions *are* supported by libxslt so you might want to check if exslt functions are included in this exslt support (see e.g. http://www.jenitennison.com/xslt/exslt/functions/). Or you could implement your functions in Python and make them available in XSLT (http://lxml.de/extensions.html).

xsl:function and this particular XPath expression -- (1 to 4 * ($s - 2) -- are XSLT 2.0 features. libxslt supports only XSLT 1.0 and EXSLT. It does support EXSLT functions though, so you can start with that: http://www.w3.org/1999/XSL/Transform" xmlns:foo="whatever" xmlns:exf="http://exslt.org/functions" extension-element-prefixes="exf">  Kind regards, Mikhail On 11/15/2017 4:39 PM, P.
