Hi,I have a simple PHP code $dom = new DomDocument;$dom->Load('test.xml');$xpath = new DOMXpath($dom);$node = $xpath->query('/contacts')->item(0);echo $node->nodeName . "\n";$GLOBALS['dom']->removeChild($GLOBALS['dom']->lastChild);$dom->save('test.xml'); and an XML file named 'test.xml' <?xml version="1.0" encoding="ISO-8859-1"?> <contacts> <entry uri="sip:vinayg@company.org"> <name>Vinay</name> <sip> sip:vinayg@company.org </sip> <Number> 9885821530 </Number> </entry> <entry uri="sip:vivek@company.org"> <name>Vivek</name> <sip> sip:vivek@company.org </sip> <Number> 9885821530 </Number> </entry> </contacts> My intention of this program is to delete only the entry tag with uri as 'sip:vivek@company.org' and all its child nodes (name, sip and Number). When I execute the above code the whole file is erased and there is no error or warning. Where am I wrong ?I would be happy for any help in correcting my code or redoing it as I am new to PHP and XML.My desired output of test.xml after execution is: <?xml version="1.0" encoding="ISO-8859-1"?> <contacts> <entry uri="sip:vinayg@company.org"> <name>Vinay</name> <sip> sip:vinayg@company.org </sip> <Number> 9885821530 </Number> </entry> </contacts> Thanx in advance.Regards,tvks
