I could read the content of the xml file to a string and use string operations to achieve this, but I guess there is a more elegant way to do this. Since I did not find a clue in the docus, I am sking here:
Given an xml (see below) file, how do you count xml tags, like count of author-tags in the example bewlow the most elegant way? We assume, that each author appears exactly once.
<root>
<author>Tim</author>
<author>Eva</author>
<author>Martin</author>
etc.
</root>
This xml file is trivial, but it is possible, that the authors are not always listed one after another, there may be other tags between them.
