RE: QxmlDOM_Node_getNodeValue and error from the parser

["Bartell, Aaron L. (TC)" <ALBartell@xxxxxxxxxxxxxx>]

You first need to check to see if <Status> has any "children" and also check
the Qxml_DOMRTNCOD and Qxml_ErrorType provided fields for errors before
continuing.  Here is how I do it in my DOMParse API's which are downloadable
from http://mowyourlawn.com

HTH,

Subject: QxmlDOM_Node_getNodeValue and error from the parser


Hi,

I am doing a small application that uses the XML toolkit to read/write files
in the IFS.
I am reading one file that has an empty tag, f.e. <Status></Status>

When I do:

     C                   EVAL      p_ChlNode = QxmlDOM_Node_getFirstChild
     C                                 (p_Node)
     C                   IF        QxmlDOM_Node_getNodeType(p_ChlNode) =
     C                             Qxml_TEXT_NOD
     C                   EVAL      p_ChlValue = QxmlDOM_Node_getNodeValue
     C                                 (p_ChlNode)

And the tag is empty, I get the error message MCH3601 when performing the
QxmlDOM_Node_getNodeValue operation.
How can I avoid it?
Thanks for your time.
