Hi, guys!
I'm trying to create the following XML by XPath:
my $xmlTree = XML::XPath->new(xml => '<a></a>');
$xmlTree->createNode( '/a/b/item[@type = \'A\'][1]/subitem[@name =
\'QQQ\']/@value');
my $d = $xmlTree->find('/a');
my $xml = XML::XPath::XMLParser::as_string(($d->get_nodelist)[0]);
$xml =~ s/></>\n</g;
$xml =~ s/"/'/g;
print "$xml\n";
expected XML:
<a>
<b>
<item type='A' id='1'>
<subitem name='QQQ' value='' />
</item>
</b>
</a>
resulted XML:
<a>
<b>
<item[((attribute::type) = ('A'))][(1)]>
<subitem[((attribute::name) = ('QQQ'))] value='' />
</item[((attribute::type) = ('A'))][(1)]>
</b>
</a>
During the debug I found the issue in func
XML::XPath::Node::ElementImpl::new(/usr/lib/perl5/vendor_perl/5.8.8/XML/XPath/Node/Element.pm:23)
It gets name 'subitem[((attribute::name) = (\'QQQ\'))]' and doesn't
try to create attributes out of it.
The only way to fix the issue I found so far is to create all missing
tags before calling the desired function:
$xmlTree->createNode( '/a/b/item/@type');
$xmlTree->setNodeText( '/a/b/item/@type', 'A');
$xmlTree->createNode( '/a/b/item[@type = \'A\']/@id');
$xmlTree->setNodeText( '/a/b/item[@type = \'A\']/@id', '1');
$xmlTree->createNode( '/a/b/item[@type = \'A\']/subitem/@name');
$xmlTree->setNodeText( '/a/b/item[@type = \'A\']/subitem/@name', 'QQQ');
$xmlTree->createNode( '/a/b/item[@type = \'A\']/subitem[@name =
\'QQQ\']/@value');
$xmlTree->setNodeText( '/a/b/item[@type = \'A\']/subitem[@name =
\'QQQ\']/@value', 888);
But it has it's limitations (with "[1]" part) & complexity.
Can you please help with this issue?
Thanks.
