Hi, Thank you for the replies. I did what you said, this HAS FIXED the localName issue. Thank you very much. However, the very next test in the isEqualNode code is a check of getNamespaceURI()'s. This fails.
What seems to be happening is that the object that we create from the byte stream seems to have the valid NamespaceURI but the orginial object does not. What would be causing this? Again thanks for your help! -dh -----Original Message----- From: Gareth Reakes [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 02, 2002 8:30 AM To: [EMAIL PROTECTED] Subject: RE: Serialize and unserialize DOMDocument over socket Hi, The problem is 2 fold. First you have not set the namespaces feature on DOMBuilder to true - do that like this: pDOMBuilder->setFeature(X("namespaces"), true); secondly you are mixing level 1 and level 2 creation methods. createDocument uses level 2 (createElementNS) and therefore it will not compare correctly with localName if you then create it with level 1. Prefer using createXXXNS.
