I have a simple function included from an external stylesheet being called using the code (snipped) below

mystylesheet.xslt
...
<xsl:include href="C:\XSLT_DEV\myfuncs.xsl"/>
...
<xsl:call-template name="myfuncs:max">
<xsl:with-param name="values" select="ID"/>
</xsl:call-template>

-------------
myfuncs.xsl
....
<xsl:template name="myfuncs:max">
<xsl:param name="values"/>
<xsl:variable name="max">
<xsl:for-each select="$values">
<xsl:sort data-type="number" order="descending"/>
<xsl:if test="position() = 1">
<xsl:value-of select="."/>
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:value-of select="$max"/>
</xsl:template>

Which works fine in stylus studio using all but the "java builtin" and "custom" processors which i've setup to use Xalan 2.7.1

Sadly our application uses Xalan-J 2.7.1. Can anyone think of a reason this will not work using the java based engines? Could it be that since it's a recursive function that it's a memory issue. It's only being called with maybe 5 or 6 ID's??

Any help will be met with more than ample gratitude.

TIA

Hi Keri,

The include statement is using a windows path but it should rather use a URL

<xsl:include href="file:///C:/XSLT_DEV/myfuncs.xsl"/>

If the the included XSLT is in the same folder of the main XSLT simply use

<xsl:include href="myfuncs.xsl"/>

Hope this helps

I agree with your analysis and have put this right however, I would have got an error had the mysheet.xslt not been able to include the myfuncs.xsl file.
I've now put the "function" inline, of course it's ceased to be a function like this and it seems to work ok, I think though, just a little inelegant.

<xsl:variable name="maxDOB">
<xsl:for-each select="IP_DOB/ID">
<xsl:sort data-type="number" order="descending"/>
<xsl:if test="position()=1">
<xsl:value-of select="."/>
</xsl:if>
</xsl:for-each>
</xsl:variable>
