I'm using XPath to parse an XML file of blog posts and comments. Here's an example of the file structure:

<entry>
  <title>Title of the post</title>
  <content>Content of the post</content>
  <category term="blog"/>
  <category term="label"/>
  <category term="another label"/>
  <category term="blah"/>
  ...
</entry>

The first category element indicates the type of entry--whether or not the entry is a blog post or a comment. Any subsequent category elements indicate the blog post tags.

I can easily get the first instance of category like so:

foreach my $entry (reverse($xc->findnodes('//post:entry'))) {
    my $type =  $xc->findvalue('./post:category[1]/@term', $entry);
    ...
}

And I can get the subsequent values by referencing post:category[2]/@term, or any other number.

I can even get all subsequent values using this xpath:

my $category = $xc->findvalue('./post:category[position()>1]/@term', $entry);

Unfortunately, though, when I use position()>1 it sticks all the values in one variable, like "labelanother labelblah". What's the best way to keep the values separate? when retrieving them with xpath?
