Subject: [xsl] Patterns and scoped variables (or rather lack thereof) From: Ihe Onwuka <ihe.onwuka@xxxxxxxxx> Date: Sat, 15 Feb 2014 20:42:12 +0000 |
Transforming this sort of markup <div class="fr small subtle">Transaction date: Sep 26, 2013</div> into a key value pair. <Transactiondate>Sep 26, 2013</Transactiondate> However if there are too many words before the colon separator (the key part) then it probably isn't suitable for the key value treatment (the code below uses 3 words as the cutoff point). Talking of the code below and the thread title, the issue is how many times I've had to (or think I've had to ) tokenize the string on colon because I cannot (or think I cannot) introduce a let scoped variable into the pattern. <xsl:template match="text()[count(tokenize(.,':')) eq 2 and count(tokenize(tokenize(.,':')[1],'\s+')) lt 4]"> <xsl:variable name="keyValue" select="tokenize(.,':')"/> <xsl:element name="{replace($keyValue[1],'\s+','')}"> .....key..... <xsl:value-of select="$keyValue[2]"/> ......value..... </xsl:element> </xsl:template> How else do I think I could do this. <xsl:template match="text()"> <xsl:call-template name="dealWithText" </xsl:template> <xsl:template name="dealWithText"> <xsl:variable name="keyValue" select=tokenize ...etc> <xsl:choose> <xsl:when etc which of course camouflages the matchng rule inside the call template. Is this the best that can be done or have I missed something.
