RE: [xsl] regular expression issue in XSLT 2.0

["Michael Kay" <mike@xxxxxxxxxxxx>]

You may find it less confusing to put the regular expression in a variable:

<xsl:variable name="regex" select="'(.*)\{\$gemeente\}'"/>
<xsl:analyze-string regex="{$regex}">

Another solution is to write it as regex="{'........'}"

<xsl:analyze-string regex="{'(.*)\{\$gemeente\}'}">
