Iterating through a substring

[aidy]

Hi,

I am using XPath and XSLT and I have a string containing something like
this:

"gbahes75\Projects\AddressService\Datapool\EnterAd dress.sdd"

I want to get'EnterAddress.sdd', and I am using the function
'substring-after'

(note:
MESSAGE_TEXT="gbahes75\Projects\AddressService\Dat apool\EnterAddress.sdd")

substring-after(MESSAGE_TEXT,'\')

But I am unsure on how to get the value after the *last* '\'

Thanks

Aidy

You were already told to write a recursive named template to which you
pass the whole string as a parameter and then apply e.g. substring-after
until you have found the last part.

Quite easy, but you need to use recursion
<xsl:template name="str-path-2-filename" xml:space="default" >
<xsl:param name="path" select="/.." />

<xsl:param name="left-path" select="substring-after ($path, '/')" />

<xsl:choose >
<xsl:when test="$left-path != '' " >
<xsl:call-template name="str-path-2-filename" >
<xsl:with-param name="path" select="$left-path" />
</xsl:call-template>
</xsl:when>

<xsl:otherwise ><xsl:value-of select="$path" /></xsl:otherwise>
</xsl:choose>
</xsl:template>
