need variable in analyze-string regex

2003-06-06 08:24:50
Hello, I recently started with XSLT and got a couple of
questions...

I appear to need variables in the style of:-

 <xsl:analyze-string select="$pattern" regex="$regex">

becuse I need to apply different regexs to the same input.
The number of regexs to process are defined in elsewhere.
(I realize this is not directly supported).

<!-- sample regex file -->
<RegexList>
  <Regex>.*</Regex>
  <Regex>^[0-9]+</Regex>

I thought about generating the xsl from the regex.xml as
that way the regex would be strings, any better ideas ?

XPath 2.0 will support regexs, when is the first XPath 2.0
engine likely to be available ?

One other list member outlined a method of using the java Perl
regex, by calling Java from XSL.  Was this work ever completed ?


My original problem XSL

<xsl:template match="/">
  <!-- write XMLoutput root tag -->
  <PatternGeneratedTable>
    <JazzPatternSet>

  <!-- cycle through our list of regexes -->

  <xsl:for-each select="$patternRegex//PatLstSel">
   <xsl:variable name="regex" select="."/>
   <xsl:element name="Test">
    <xsl:value-of select="./parent::Test/@Name"/>
   </xsl:element>

    <Group>

  <!-- cycle through PatternNames, apply regex to each -->
  <xsl:for-each select="$patternList//Pattern">

    <!-- cache patternName -->
    <xsl:variable name="pattern" select="current()/."/>

    <xsl:analyze-string select="$pattern" regex="$regex">
      <xsl:matching-substring>
        <!-- we have a match -->
        <!-- write out the cached patternName -->
        <PatternName><xsl:value-of select="$pattern"/></PatternName>
      </xsl:matching-substring>
      <xsl:non-matching-substring/>
    </xsl:analyze-string>

  </xsl:for-each>
    </Group>

  </xsl:for-each>


  <!-- close XMLoutput root tag -->
  </JazzPatternSet>
  </PatternGeneratedTable>
</xsl:template>
 

Thanks, John.
