Re: empty element as an end-marker

2003-03-28 01:44:30
my problem is easily explained. This is the simple xml:

<p>some text some text <pb/>more text more text</p>

In my (html) output I need to process and reproduce the 'some text'
(ie. up
to the <pb/>) without the 'more text'. (Of course I also need to
output
just
the 'more text' in another instance.) I'm having some trouble with
this.
Also the 'some text' contains tags which need to be processed by the
stylesheet.

The following is an outline of a general way to process groups of nodes
delimited by a specific element. This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:output omit-xml-declaration="yes" indent="yes"/>

  <xsl:template match="/">
    <xsl:apply-templates select="/*/p/pb"/>
  </xsl:template>
  
  <xsl:template match="p/pb">
    <xsl:element name="group{position()}">
      <xsl:apply-templates 
      select="preceding-sibling::node()[not(self::pb)]
                       [generate-id(following-sibling::pb)
                       = 
                        generate-id(current())
                        ]"/>
    </xsl:element>
    <xsl:if test="position() = last()">
      <xsl:element name="group{position() + 1}">
        <xsl:apply-templates select="following-sibling::node()"/>
      </xsl:element>
    </xsl:if>
  </xsl:template>
</xsl:stylesheet>

when applied on this source.xml:

<html>
  <p>some text1 some text1 
  <pb/>more text2 more text2
  <pb/>more text3 more text3
  </p>
</html>

produces:

<group1>some text1 some text1 
  </group1>
<group2>more text2 more text2
  </group2>
<group3>more text3 more text3
  </group3>

As we see, all nodes between two consecutive markers will be processed
as a group.
