regex with XML tags

Question

I currently work on an XML parser, and I need to use regex to get all my tags to put them in a tree.

My file looks like

<block1>
   <tag1>
       <subtag1>a</subtag1>
       <subtag2>b</subtag2>
   </tag1>
   <tag2>
       <subtag3>c</subtag3>
       <subtag4>d</subtag4>
   </tag2>
</block1>

I would like my regex to match with

<block1>
<tag1>
<subtag1>
<subtag2>
<tag2>
<subtag3>
<subtag4>

To avoid getting the end tags I escaped the "/" and it works quite well.

My last problem is that I get the whole single-line tags because the first "<" goes with the last ">"...

I am using

boost::regex r("(<[^/].*>)");

Thanks in advance,
