I have the following code in another application that workes fine
namespace declaration xmlns:xasp="urn:asp-objects">

    <xsl:variable name="offer-url">
      <xsl:value-of select="yahoo:Url" />
</xsl:variable>
 <xsl:variable name="offer-url-encoded">
      <xsl:value-of select="xasp:encodeURL(string(yahoo:Url))" />
</xsl:variable>

I am trying to re use this in another xsl but i am getting this error

Error in XPath expression
Unknown function - Name and number of arguments do not match any function signature in the static context - 'urn:asp-objects:encodeURL'

can anyone help me with this please

this is either an external function,
so you will need a bunch of other things
including making the extension function library accessible
(eg. if java, make sure the jar is on the classpath)

or this is a XSLT2 function,
make sure that yu include the definition then and that your stylesheet is an XSLT2 stylesheet and you have an XSLT2 processor

lots of things that cann go wrong.

I think it would b esmart if you posted both the XSLT that had this working and the XSLT that has this not working

yep, that is likely an extension library
what processor are you using on the computer that does work?
it is hard for me to tell how the extension library is configured.
There likely is a jar on the classpath that is included
or a .dll that is connected one way or another.
You have to make sure that you copy and configure that as wel
