Hi
I've been using xslt on and off for a few years, but not for long enough to
make me feel like I've moved on from 'novice' status yet. The problem I'm
grappling with at the moment is really making feel like I don't understand even
the fundamentals yet!
What I'm trying to do is process some xml of which this is a fragment:
<aff id="aj266199af2">
<label>2</label>National Radio Astronomy Observatory, Chile<xref
ref-type="fn" rid="aj266199afn4"><sup>9</sup></xref>; <ext-link
ext-link-type="email" id="aj266199em4">email address here</ext-link>
</aff>
<!-- snip -->
<fn id="aj266199afn4">
<label>9</label>
<p>The National Radio Astronomy Observatory is a facility of the National
Science Foundation operated under cooperative agreement by Associated
Universities, Inc.
</p>
</fn>
The problem is the trailing semi-colon between the <xref> & <ext-link> elements.
Previously to remove characters like this I have seen this sort of thing
successfully employed elsewhere:
<xsl:variable name="searchStr" select="'[:;,\.\s]+$'"/>
<xsl:variable name="replaceStr" select="''"/>
<!-- snip -->
<xsl:variable name="affilStr">
<xsl:apply-templates select="key('key_allElementsById' , .)"/>
</xsl:variable>
<affil id="{.}">
<xsl:value-of select="replace($affilStr , $searchStr , $replaceStr)"
/>
However the above xml snippet is dealt with by this:
<xsl:for-each select="//aff">
<affil id="{label}">
<xsl:apply-templates />
</affil>
</xsl:for-each>
... and this is the output:
<affil id="2">National Radio Astronomy Observatory, Chile<footnote pos="affil"
id="9">The National Radio Astronomy Observatory is a facility of the National
Science Foundation operated under cooperative agreement by Associated
Universities, Inc.</footnote>; </affil>
However if I try to employ the same method to remove the semi-colon:
<xsl:variable name="searchStr" select="';\s*$'"/>
<xsl:variable name="replaceStr" select="''"/>
<xsl:variable name="nameStr">
<xsl:apply-templates/>
</xsl:variable>
<affil id="{label}">
<xsl:value-of select="$nameStr"/>
</affil>
The result is as follows:
<affil id="2">National Radio Astronomy Observatory, ChileThe National
Radio Astronomy Observatory is a facility of the National Science Foundation
operated under cooperative agreement by Associated Universities, Inc.</affil>
We've lost the semi-colon (excellent!) but also structure of the xml, the
<footnote> tags. :-(
Would anyone be able to comment on my approach and point out what would be a
more sensible approach?
I'm using saxon to process the xml with xslt v2.
Many thanks
Richard
