I am trying to modify an xsl which is of the older version. I come across the following
<xsl:eval>FormatAccount(this)</xsl:eval>
<xsl:script>
function FormatAccount(e) {
// function details
}
</xsl:script>
I am trying to call the FormatAccount() javascript function using `<xsl:eval>` and the function is written in `<xsl:script>`.
How to do this as per the latest standards????
Embedded extension functions in other language is not the content model of XSLT.
Extension elements and extension functions are part of the content model as described in http://www.w3.org/TR/xslt#extension : it's implementation dependant how exactly an XSLT processor register those extensions.
As pointed by @Martin Honnen's answer, in XSLT 2.0 you can declare "stylesheet functions" with XSLT itself.
The latest standard is XSLT 2.0 http://www.w3.org/TR/xslt20/, it does not have any facility to define functions in Javascript, it however allows you to define functions with XSLT itself: http://www.w3.org/TR/xslt20/#stylesheet-functions. XSLT 2.0 is supported by XSLT 2.0 processors like Saxon 9 http://saxon.sourceforge.net/, AltovaXML Tools http://www.altova.com/altovaxml.html or XQSharp http://www.xqsharp.com/xqsharp/beta.htm.
If you want to use Javascript to define extension functions we need to know which XSLT processor you use, of those three XSLT 2.0 processors I mentioned I think only AltovaXML Tools allows that (http://manual.altova.com/AltovaXML/altovaxmlcommunity/index.html?xextmsxsl.htm), and only, I think, to allow easier migration of XSLT 1.0 stylesheets written for Microsoft MSXML.
If you want to use an XSLT 1.0 processor then there too defining extension functions in a particular programming language like Javascript depends on the processor you use, for MSXML there is an
msxsl:script
