XSLT- Trying to negate a String() function

I have attached some XSLT code, the code is fairly repetitive in that a a template i have replaced with the comment   <!--DO STUFF1() --> is called in two places.

I think I could improve the code by using a negating my NOT condition, but I cant seem to make it work properly.

I want to try and say <xsl:when test="
string(substring-after(substring-after($path, '\'), '\')) ">  OR'ed with <xsl:when test="string(substring-after($path, '\')) ">


And help would be greatly received.

Even if its a complete restructure of the code.

Thanks



<xsl:choose>
		<xsl:when test="starts-with($path,'\')"> <!-- Starts with \ - e.g \abc\def\ghi -->
			<xsl:choose>
				<xsl:when test="not (string(substring-after(substring-after($path, '\'), '\'))) ">
					<!--DO STUFF1() -->
				</xsl:when>
				<xsl:otherwise>
					<xsl:call-template name="xxx">
						<xsl:with-param name="$path" select="substring-after(substring-after($path, '\'), '\')"/>
					</xsl:call-template>
				</xsl:otherwise>
			</xsl:choose>
		</xsl:when>
		<xsl:otherwise> <!-- Doesn't start with \ - e.g abc\def\ghi-->
			<xsl:choose>
				<xsl:when test="not (string(substring-after($path, '\'))) ">
					<!--DO STUFF1() -->
				</xsl:when>
				<xsl:otherwise>
					<xsl:call-template name="xxx">
						<xsl:with-param name="$path" select="substring-after($path, '\')"/>
					</xsl:call-template>
				</xsl:otherwise>
			</xsl:choose>
		</xsl:otherwise>
	</xsl:choose>

I think it would greatly simplify your stylesheet if you created a path2 variable first that had the leading "\" stripped off
        <xsl:variable name="path2">
            <xsl:choose>
                <xsl:when test="starts-with($path,'\')"> <!-- Starts with \ - e.g \abc\def\ghi -->
                    <xsl:value-of select="substring($path, 2)"/>
                </xsl:when>
                <xsl:otherwise> <!-- Doesn't start with \ - e.g abc\def\ghi-->
                    <xsl:value-of select="$path"/>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:variable>
        <xsl:choose>
            <xsl:when test="not (string(substring-after($path2, '\'))) ">
                <!--DO STUFF1() -->
            </xsl:when>
            <xsl:otherwise>
                <xsl:call-template name="xxx">
                    <xsl:with-param name="$path" select="substring-after($path2, '\')"/>
                </xsl:call-template>
            </xsl:otherwise>
        </xsl:choose>

I'll take a look at that. The 'path' can be like :

c:\window\temp or

\server\temp

hence the conditional processing

I realized that would be the case,
I saw that once you are sure that the possible leading "\" is gone, the processing is exactly the same
you process the bit after the first "\" if it is there, not counting the leading one
so you could first drop that

Yes that quite correct, I also call that function recursively, so that i can iterate over the whole path. So i guess that means i will be assigning a value to $path2 every time - I suppose i can move the variable outside the function call ?
