Doug PotterSubject: PRoblems with XML-XML structure conversion
Author: Doug Potter
Date: 06 Aug 2002 10:39 PM 
Actually the structure is OK, it's the repetitions that are causing me problems. What I've got for source data is data that was originally header-detail but got flattened when exported to XML.

root
  hd1  1   /hd1
  hd2  A   /hd2
  ln1  10  /ln1
  ln2  10A /ln2
/root
root
  hd1  1   /hd1
  hd2  A   /hd2
  ln1  20  /ln1
  ln2  1A  /ln2
/root
root
  hd1  2   /hd1
  hd2  B   /hd2
  ln1  10  /ln1
  ln2  2A  /ln2
/root

Note that the first two roots have the same h1 and h2 data.

What I need is something like:

root
  hd
    hd1  1   /hd1
    hd2  A   /hd2
  /hd
  ln
    ln1  10   /ln1
    ln2  10A  /ln2
  /ln
  ln
    ln1  20   /ln1
    ln2  1A   /ln2
  /ln
/root
root
  hd
    hd1  2   /hd1
    hd2  B   /hd2
  hd
  ln
    ln1  10  /ln1
    ln2  2A  /ln2
  ln
/root



But what I am getting is:

root
  hd
    hd1  1   /hd1
    hd2  A   /hd2
  /hd
  ln
    ln1  10   /ln1
    ln2  10A  /ln2
  /ln
/root
root
  hd
    hd1  1   /hd1
    hd2  A   /hd2
  /hd
  ln
    ln1  20  /ln1
    ln2  1A  /ln2
  /ln
/root
root
  hd
    hd1  2   /hd1
    hd2  B   /hd2
  /hd
  ln
    ln1  10  /ln1
    ln2  2A  /ln2
  /ln
/root

If there was a xsl:for-each-unique select="root/h1" available, that might work, but that doesn't exist.

Any help would be appreciated.

Thanks

Doug

I could not exaclty follow the logic of your grouping example
Try to play with the following solution

{?xml version="1.0" encoding="UTF-8"?}
{xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"}
{xsl:output method="xml" indent="yes"/}
{xsl:template match="/"}
{r}
{xsl:for-each select="r/root"}
{xsl:choose}
{xsl:when test="(starts-with(name(*[1]), 'hd') and
not(*[1] = following-sibling::root/descendant::*)) or
not(starts-with(name(*[1]), 'hd'))"}
{root}
{xsl:call-template name="for-each-group"}
{xsl:with-param name="prefix" select="'hd'"/}
{/xsl:call-template}
{xsl:call-template name="for-each-group"}
{xsl:with-param name="prefix" select="'ln'"/}
{/xsl:call-template}
{/root}
{/xsl:when}
{/xsl:choose}
{/xsl:for-each}
{/r}
{/xsl:template}

{xsl:template name="for-each-group"}
{xsl:param name="prefix"/}
{xsl:param name="group"/}
{xsl:variable name="set" select="descendant::*[starts-with(name(),
$prefix)]"/}
{xsl:if test="$set"}
{xsl:element name="{$prefix}"}
{xsl:for-each select="$set"}
{xsl:copy-of select="."/}
{/xsl:for-each}
{/xsl:element}
{/xsl:if}
{/xsl:template}
{/xsl:stylesheet}
