RE: Namespace 'http://exslt.org/regexp' does not contain anyfunctions.

Craig,
I am not familiar with the particular routine you are using but we have had
the same issues as yourself with routines such as date:add, date:difference
etc.

In a nutshell, you cannot use stuff similar to
select="date:add($startDate,$endDate) with MSXML etc.
But if you want correct results using .NET etc. you need to use the routine
as you have it.

Unfortunately, using MSXML is very useful for testing...so here is how we
handle it.

<xsl:param name="EXSLTREF">yes</xsl:param>

<xsl:element name="Value">
	<xsl:choose>
		<xsl:when test="$EXSLTREF = 'yes'">
			<xsl:call-template name="date:add">
				<xsl:with-param name="date-time">
					<xsl:value-of select="$startDate"/>
				</xsl:with-param>
				<xsl:with-param name="duration">
					<xsl:value-of select="$endDate"/>
				</xsl:with-param>
			</xsl:call-template>
		</xsl:when>
		<xsl:otherwise>
			<xsl:value-of
select="date:add($startDate,$endDate)"/>
		</xsl:otherwise>
	</xsl:choose>
</xsl:element>

We ensure that when stuff is running under .NET, then we get the application
to set "EXSLTREF" to "no", thus ensuring that should the xslt have the value
set to 'yes' there is no runtime problem.

Hope this helps.
Regards
David

Subject: [exslt] Namespace 'http://exslt.org/regexp' does not contain
anyfunctions.

I was looking through the archives and found a question raising this
issue but no response.  I am using MSXML4 processor (as part of
Marrowsoft's XSelerator, but it does the same thing from explorer and
Altova's XMLSpy) and I get the following above error with the following
style sheet. I haven't got to the point where I can even test the actual
regular expression; the output crashes with the above error as soon as
it hits the regexp code.

Any assistance greatly appreciated..

The stylesheet nessus.xslt is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet 
	version="1.0" 
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
	xmlns:regexp="http://exslt.org/regexp" 
	extension-element-prefixes="regexp">

	<xsl:import href="c:\exslt\regexp\regexp.xsl" />
	
	<xsl:output method="xml" version="1.0" encoding="UTF-8"
indent="yes"/>
	

	<xsl:template match="/">
		<table border="1">
			<tbody>
				<xsl:apply-templates
select="report/results/result/ports/port">
					<xsl:sort select="@protocol"/>

					<xsl:sort select="@portid"
data-type="number"/>				
				</xsl:apply-templates>
			</tbody>
		</table>
	</xsl:template>
	
	<xsl:template match="port">
		<tr valign="top">
			<td><xsl:value-of select="information/id"/></td>

			<xsl:choose>
				<xsl:when test="@portid">
					<td><xsl:value-of
select="service/@name"/>(<xsl:value-of
select="@protocol"/>/<xsl:value-of select="@portid"/>)</td>

				</xsl:when>
				<xsl:otherwise>
					<td><xsl:value-of
select="service/@name"/></td>			
				</xsl:otherwise>
			</xsl:choose>
			<td><xsl:value-of
select="information/data"/></td>			
			<td><xsl:value-of
select="information/severity"/></td>	
			<td><xsl:value-of
select="regexp:match(information/description, 'risk factor :
(low|high)', 'i')"/></td>		
		</tr>
	</xsl:template>
	
</xsl:stylesheet>
