Re: [xsl] <xsl:strip-space> does NOT work when comment lines are involved (directly before).

[Wolfgang Laun <wolfgang.laun@xxxxxxxxx>]

Trying to learn (!), I've come up with the one shown below.
@Ben: no guarantee!
@Others: I'd be grateful for any comments.


<?xml version="1.0"?>
 <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">

  <xsl:output indent="yes"/>

  <xsl:template match="@* | element() | comment() ">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*[normalize-space( concat(.,@*) )='']"/>

  <xsl:template match="text()">
    <xsl:choose>
      <xsl:when test="preceding-sibling::*[normalize-space( concat(.,@*)
)='']">
        <xsl:copy/>
      </xsl:when>
      <xsl:when test=".[normalize-space(.) !='']">
        <xsl:copy/>
      </xsl:when>
      <xsl:otherwise>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

</xsl:stylesheet>
