| Subject: | next() skips first element |
Hi,
I'm iterating through a nodelist using an XML::LibXML::NodeList::Iterator object, but next() seems to skip the first element (first() works ok though). Is this the correct behaviour? I've written a simplified testcase below which fails on:
libxml2 2.6.9
XML::LibXML 1.58
XML::LibXML::Iterator 1.00
and
libxml2 2.5.10
XML::LibXML 1.55
XML::LibXML::Iterator 1.00
Linux ltkdev 2.6.6-1.435.2.3 #1 Thu Jul 1 08:25:29 EDT 2004 i686 i686 i386 GNU/Linux (Fedora)
Thanks for your time.
Ben
