I want to access the value of sub child and modify it. This is my xml
<config xmlns:xc="urn:ietf:params:xml:ns:netconf:base:1.0">
<outer1 xmlns="http://blablabla" >
<inner>
<name>
<prenom>Hello</prenom>
</name>
<profession>warrior</profession>
</inner>
<inner>
<name>
<prenom>Hello</prenom>
</name>
<org>wwf</org>
<profession>warrior</profession>
</inner>
</outer1>
and this is my code
my $dom = XML::LibXML->load_xml( location => $xml);
my $context = XML::LibXML::XPathContext->new( $dom->documentElement() );
$context->registerNs( 'u' => '"urn:ietf:params:xml:ns:netconf:base:1.0' );
$context->registerNs( 'u' => 'http://blablabla');
for my $node ($context->findnodes('//u:inner') ) {
for my $node2 ($node->findnodes('//u:name') ) {
#if (($node->findnodes('u:name', $node2) ->size) != 1) {next;}
my ($mh) = $node->findnodes('u:prenom', $node2);
my $size = $node->findnodes('u:prenom', $node2) ->size;
print "size $size";
if ($size != 1) {next;}
$mh ->removeChildNodes();
$mh->appendText('World12456');
print "mh = $mh";
}
}
I want to access prenom and modify it to 'World12456'. With currrent code; I got this error XPath error : Undefined namespace prefix error : xmlXPathCompiledEval: evaluation failed. Then I tried different way
for my $node ($context->findnodes('//u:inner') ) {
my ($mh) = $context->findnodes('u:name/prenom', $node);
my $size = $context->findnodes('u:name/prenom', $node) ->size;
print "size $size";
if ($size != 1) {next;}
$mh ->removeChildNodes();
$mh->appendText('World12456');
print "mh = $mh";
}
Then I get the size is 0 for both. It doesn't find the tag prenom. With
for my $node ($context->findnodes('//u:inner/name')
It displays nothing.
I am sorry if this is duplicate but I don't find any link to access the sub child with xpathcontext yet.
I got it . I just need to put u for each element
