Basically my XML data structure allows elements to contain data or other
elements, like so:
<fruits>
<fruit>apple</fruit>
<fruit>banana</fruit>
<fruit>
<fruit>pear</fruit>
<color>green</fruit>
</fruit>
<fruit>
<fruit>orange</fruit>
<color>orange</color>
</fruit>
</fruits>
This structure is slightly confusing; you have two 'fruit' nodes which mean
different things.
Consider the following:
<fruit>
<name>apple</name>
</fruit>
<fruit>
<name>pear</name>
<color>green</color>
</fruit>
or:
<fruit>apple</fruit>
<fruit color="green">pear</fruit>
which are probably a bit clearer.
I just wanted to select the fruit name using templates, but if I did this:
<xsl:templates match="fruit">
I get all fruit nodes(term?) and also the colors as well. So my output was:
apple
banana
pear
green
orange
orange
If you have an <xsl:apply-templates /> element in a <xsl:template match="...">
element then the child nodes will be processed as well.
If you want elements to be left out you can define empty templates for them:
<xsl:template match="color" />
Or if you use the second of the modified XML structures above you can use
<xsl:template match="fruit">
where the context will be the name of the fruit and @color will be its colour.
(You may also want to look at the <xsl:for-each> element.)
