JS reads the value of a remote XML node (compatible with Firefox)

　　Fire Station Building Institute (Bkjia.com) Technical DocumentationThis article mainly introduces an example that is compatible with firefoxfirefox's JS to read the value parameters of a remote XML node.

Parameters:
Str_xmlUrl: Remote XML address, for example, http: // 192.168.1.19/test/xml. xml
Str_dirPath: Path of the node to be searched, for example, XMLDocument/test [0]/newName2/childs [2]

JS Code:

Reference content is as follows: <Script type = "text/javascript"> Function getXMLNode (str_xmlUrl, str_dirPath) { If (! Str_xmlUrl |! Str_dirPath) Return false; Var _ bool_IE = (window. ActiveXObject? True: false); // obtain the browser type // Initialize the XMLDocument object Var _ obj_xmlDoc; If (_ bool_IE) _ Obj_xmlDoc = new ActiveXObject ('Microsoft.
