Subject: Re: [xsl] Selecting all nodes between pairs of <br> tags From: "Mukul Gandhi" <gandhi.mukul@xxxxxxxxx> Date: Mon, 19 Jun 2006 10:18:30 +0530 |
Hi Duncan, Sorry for replying a bit late to your question.
<xsl:if test="not((local-name($nodeset[1]) = 'br') and (local-name($nodeset[2]) = 'br'))">
I could not give this code earlier because your source XML data was not enough for me to formulate this solution.
Regards, Mukul
Hi List,
I am still having trouble grasping some of the more subtle points of XPath. Consider the following HTML:
... <br><br> <b>A</b>B<br> ... <br><br> C <br><br> <div> ...
Following the advice of Mukul Gandhi given me a few weeks ago, I use match="br[local-name(preceding-sibling::node()[1]) = 'br'][1]" (I am using xsltproc with the --html option, which I suspect is normalizing the spaces so this is slightly modified from the sample given):
I then select the nodes following with select="following-sibling::node()[normalize-space != '']" - this is then passed into a template which which outputs the A and B elements (I handle these explicitly, which may be cheating, because I can't figure out how to stop at <br> and I know the format of the data).
This is all well and good, except that my output comes out like this:
<ul> <li><label>A</label>B</li> ... <li><label>C</label></li> <b>A</b><br> ...
Currently, the selection of following siblings seems to select up to the 3rd <br> pair. This in itself is slightly odd, since I would have thought it would select everything following at the same level, although it appears to stop at the div tag, so perhaps the match ends there for some pre-determined reason. In any case, I would like it to stop at the second <br> tag pair - it seems like using a following-sibling rule inside a predicate won't work easily since elements after the 2nd <br> pair are followed by the 3rd <br> pair, so would still be included. There must be some way to specify all following siblings up to <br><br> and excluding anything after the <br><br> but the thought of what that expression might look like is making my eyes glaze.
The other problem is the labels being output afterwards - it would seem that this is matching where the previous template leaves off. I don't understand why it outputs only the label and not the following data. Any suggestions?
The relevant template:
<xsl:template match="br[local-name(preceding-sibling::node()[1]) = 'br'][1]">
<ul>
<xsl:call-template name="stat">
<xsl:with-param name="nodeset"
select="following-sibling::node()[normalize-space() != '']" />
</xsl:call-template>
</ul>
</xsl:template>
<xsl:template name="stat">
<xsl:param name="nodeset" />
<xsl:for-each select="$nodeset[position() mod 2 = 1]">
<li>
<label><xsl:value-of select="." /></label>
<xsl:value-of select="normalize-space(following-sibling::text())" />
</li>
</xsl:for-each>
</xsl:template>
Thanks in advance. Duncan
