Hello Perl Monks.

I need to filter a potentially huge xml file. The simplified structure looks like this:

<doc>
<text>
<p>
text1 p1
</p>
...
</text>
<text>
<p>
text2 p1
</p>
</text>
...
</doc>

I need to get the text content of each <text> node, call a binary that processes the text and evaluates whether the current <text> node is to be removed.

My idea is to hold a single <text> node in a memory, evaluate its text content and either print it immediately or forget it and process the next <text> node.

I would like to use LibXML::Reader, but I found no way to incrementally output the XML as it goes through the nodes. I know XML::Twig can flush, but I have encountered SEGFAULT in the past while processing ~GB XML documents through it, which I was not able to debug. So I'd rather stay on the safe side with LibXML. Any idas how to tackle this problem?

Thanks a bunch!
