In xml processing I have the following element:
<abc>
<xyz>contents</xyz>
<xyz>contents</xyz>
</abc>
In the code it seems to make no diffence if I write /xyz or xyz without
the / for the xyz-node.
{\xmlindex{#1}{/xyz}{1}}
{\xmlindex{#1}{xyz}{2}}
In the reference manual I find the / used, as for example in
{\xmlfirst{#1}{/caption}}.
My question therefore: what exactly causes this behaviour? is it good
coding practice to always use /xyz in this case?
/ anchors in the #1 node
<a>
<b>
<c>c</c>
</b>
<b>
<c>c</c>
</b>
<c>c</c>
</a>
so, if #1 == a then /c is more restictive than c
also, if you know that you only need the direct child node, it's faster
as there is no need to go deeper
