GetAttr Method
Returns the value of the specified attribute.
Syntax
xml.getAttr(attrName, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This method returns the value of the attribute specified by the AttrName parameter.
If the attribute does not exist an empty string is returned. The behavior when an attribute does not exit is controlled by ErrorOnEmptyAttr.
Please refer to the AttrName, AttrNamespace, AttrPrefix, and AttrValue properties for more information.
