Can you be more specific? Are you talking about escaping control characters? Is your example correct?
use XML::LibXML;
$s = "<foo name=bobby><name>robert</name></foo></p>";
print "before: $s.\n";
$dom = XML::LibXML->load_xml(string => "<root/>");
$dom->findnodes("/root")->[0]->appendText($s);
print $dom->serialize;
$s2 = $dom->findnodes("//text()")->[0]->data;
print "after: $s2.\n";
Output:
before: <foo name=bobby><name>robert</name></foo></p>.
<?xml version="1.0"?>
<root>&ltfoo name=bobby>&ltname&gtrobert</name>&l
+t;/foo></p></root>
after: <foo name=bobby><name>robert</name></foo></p>.
