RE: [xsl] How to output partial elements?

Hi Jem!

Your problem already have been resolved (see Jeni, Stuart and Morrow's
replies) and they work with your example, but, has Stuart said, it only
work with the first <record type="continue">.

with a little change on Jeni's template it could work on every
following-sibling <record type="continue">.

heres is the xsl:

 <xsl:template match="records">
  <xsl:apply-templates select="record[@type = 'normal']" />
 </xsl:template>

 <xsl:template match="record[@type = 'normal']">
  <record>
   <xsl:copy-of select="*" />
   <xsl:apply-templates select="following-sibling::record[1][@type =
'continuation']"/>
  </record>
 </xsl:template>

 <xsl:template match="record[@type = 'continuation']">
  <xsl:copy-of select="*" />
  <xsl:apply-templates select="following-sibling::record[1][@type =
'continuation']"/>
 </xsl:template>

hope that this helps you

Subject: [xsl] How to output partial elements?


I have been bashing my brain for days over this and I need help. Here is
the (style of) input I have:

  <record n="1" type="normal">
    <foo> <x>... <y>...</y> ...</x> </foo>
    <bar> <things> ... </things> </bar>
  </record>
  <record n="2" type="normal">
    <foo> <x>... <y>...</y> ...</x> </foo>
  </record>
  <record n="3" type="continuation">
    <bar> <things> ... </things> </bar>
  </record>
  <record n="4" type="normal">
    <foo> <x>... <y>...</y> ...</x> </foo>
    <bar> <things> ... </things> </bar>
  </record>

The problem is <record>s 2 and 3: they need to be concatenated. (The 'n'
attribute is irrelevant: I only put it there for easy reference in
illustration.)

At first I thought this was easy:

   have a template to match <record>
   if (@type != "continuation") {
     write "</record>" to the output
   }
   write "<record>" to output
   copy all child nodes to output

But XSLT won't allow partial (malformed) XML to be written to the output
tree from a <xsl:template> -- so I can't do this!
*Everyone* tells me XSLT is "the right tool" for this sort of task: but
if I'd followed my natural inclination and hacked it up in Perl it'd be
trivial to chop the offending two lines out! :)

Any ideas how to make the output look like this:

  <record type="normal">
    <foo> <x>... <y>...</y> ...</x> </foo>
    <bar> <things> ... </things> </bar>
  </record>
  <record type="normal">
    <foo> <x>... <y>...</y> ...</x> </foo>
    <bar> <things> ... </things> </bar>
  </record>
  <record type="normal">
    <foo> <x>... <y>...</y> ...</x> </foo>
    <bar> <things> ... </things> </bar>
  </record>
