removeChild (oldChild)
Removes the child node indicated by oldChild from the list of children, and returns it.

Return Value: The node removed.

DOMExceptions:

NO_MODIFICATION_ALLOWED_ERR
Raised if this node is readonly.

NOT_FOUND_ERR
Raised if oldChild is not a child of this node.


[解决办法]
最关键的一个地方你写错了


my $nodes=$doc->getElementsByTagName("allProperty"); 这里返回的应该是数组。所以你不应该用$nodes.应该用@nodes

$doc->removeChild($nodes); 这里呢，你必须针对每个node单独处理。可以针对@nodes for一下
[解决办法]

Perl code

my $parser=new XML::DOM::Parser;  my $doc=$parser->parsefile("d://news_temp.xml"); my $nodes=$doc->getElementsByTagName("allProperty"); my $parent=$nodes->[0]->getParentNode();$parent->removeChild($nodes->[0]);
[解决办法]
Perl code
use strict;use warnings;use XML::DOM;my $parser=new XML::DOM::Parser; my $doc=$parser->parse(<<XML);<root>  <allProperty>        <news_title>yes</news_title>  </allProperty></root> XMLmy $nodes = $doc->getElementsByTagName("allProperty");my $node = $nodes->item(0);$node->getParentNode->removeChild($node); # delete allPropertyprint $doc->toString();
