Compatible Firefox firefox browser JS read the value of a node in the remote XML

The initial idea was to register to determine if the user name to register was duplicated.

Parameters:
Str_xmlurl: The address of a remote XML, such as Http://192.168.1.19/test/xml.xml
Str_dirpath: The path of the node to look for, such as xmldocument/test[0]/newname2/childs[2]

JS Code:

The following is a reference fragment: <script type= "Text/javascript" > function Getxmlnode (Str_xmlurl, Str_dirpath) { if (!str_xmlurl | |!str_dirpath) return false; var _bool_ie = (window. ActiveXObject?
