If I understand correctly you want to extract the text and its enclosing tag if it has one, and just the text if it doesn't. This might help:
use XML::LibXML;
my $xml = q|
<seg>
<foo mid="0" mtype="seg">
<g id="1">Need to export this text</g>
</foo>
<foo mid="1" mtype="seg">
Need to export this text also
</foo>
</seg>|;
my $doc = XML::LibXML->load_xml(string => $xml);
my @foos = $doc->findnodes('//foo');
for my $foo (@foos) {
my $mid = $foo->getAttribute('mid');
print "mid: $mid ";
my @childnodes = $foo->childNodes();
if (@childnodes) {
for my $node (@childnodes) {
print $node->toString, "\n";
}
}
else {
print $foo->textContent, "\n";
}
}
Output:
mid: 0
<g id="1">Need to export this text</g>
mid: 1
Need to export this text also
You may need to trim leading and trailing whitespace if your XML contains it.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
