Ivan PedruzziSubject: Build safe NCName
Author: Ivan Pedruzzi
Date: 02 Aug 2011 04:12 PM
A recent post triggered my interest on how to create valid NCName while processing any arbitrary string.

Take the following example,

XML Input


You need to use the content of element nc to create XML dynamically like in the following XSLT 1.0 code

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:for-each select="/root/nc/text()">
<xsl:element name="."/>

As you may expect the above code throws run-time error

XTDE0820: Element name <.> is not a valid QName

The attached stylesheet provide a simple template that convert any arbitrary string to a valid NCName

<xsl:for-each select="/root/nc/text()">
<xsl:variable name="nc">
<xsl:call-template name="makeNCName">
<xsl:with-param name="str" select="."/>
<xsl:element name="{$nc}"/>

Hope this helps
