in reply to XPATH problems

use strict; use warnings; use XML::LibXML; my $doc1 = XML::LibXML->new->parse_file('wiki.html'); my $doc2 = XML::LibXML->new->parse_file('timeline.html'); my ($node1) = $doc1->findnodes('//div[@id="metanav"]'); my ($node2) = $doc2->findnodes('//div[@id="metanav"]'); $node1->replaceNode($node2); print $doc1->toString(0);

But the XPath you are using looks wrong. Don't you want to match {http://www.w3.org/1999/xhtml}div elements (i.e. XHTML div elements), not div elements with no namespace?

use strict; use warnings; use XML::LibXML; my $xpc = XML::LibXML::XPathContext->new; $xpc->registerNs('h', 'http://www.w3.org/1999/xhtml'); my $doc1 = XML::LibXML->new->parse_file('wiki.html'); my $doc2 = XML::LibXML->new->parse_file('timeline.html'); my ($node1) = $xpc->findnodes('//h:div[@id="metanav"]', $doc1); my ($node2) = $xpc->findnodes('//h:div[@id="metanav"]', $doc2); $node1->replaceNode($node2); print $doc1->toString(0);

[stevieb]: 16.96 hours of runtime of a Raspberry Pi on a 12v, 7.2Ah battery :) Now to watch now long it takes to recharge the battery completely with my 18v solar cells in the sun :)
[stevieb]: my high-range estimate was 18 hours
[stevieb]: battery was at about 95% capacity when the test began
[stevieb]: in the meantime while it was on battery, I got my shift register issues fixed, as well as certain interrupt issues
