XSLT使用正则表达式转换值

Question

I am using Saxon 9.8 with xslt3.0 on windows xp to transform a xml database into a normal text file with one database entry per line. but I need to process a value with regex and conditional and when I add the following portion of code:

  <xsl:analyze-string select="sbtime/@stmerid" 
    regex="([hm]{{1}})([0-9]{{1,2}})([ew]{{1}})([0-9]{{0,2}})">
    <xsl:matching-substring>
    <xsl:choose>
      <xsl:when test="regex-group(3) = 'e'">
        <xsl:text>+</xsl:text>
      </xsl:when>
      <xsl:when test="regex-group(3) = 'w'">
        <xsl:text>-</xsl:text>
      </xsl:when>
      <xsl:otherwise>
        <xsl:text>+</xsl:text>
      </xsl:otherwise>
    </xsl:choose>
    <xsl:choose>
      <xsl:when test="regex-group(1) = 'h'">
        <xsl:number value="regex-group(2)" format="01"/>
      </xsl:when>
      <xsl:when test="regex-group(1) = 'm'">
        <xsl:text>00:</xsl:text>
        <xsl:number value="regex-group(2)" format="01"/>
        <xsl:text>:</xsl:text>
        <xsl:number value="regex-group(4)" format="01"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:text>+1</xsl:text>
      </xsl:otherwise>
    </xsl:choose>
    </xsl:matching-substring>
  </xsl:analyze-string>

When I add this portion I get the following error code:

Transform.exe" -s:db_export_sample.xml -xsl:dbx_dma_zet01.xsl -o:output.txt

BTW Sorry about french language in code may not be understandable. I am not used to xslt but It seems to be correct according to xslt and saxon documentation.

Best Regards.

This was bug 3283

which was quickly fixed in a maintenance release.
