Hi all,
in a java plug-in node I need to distinguish a XML attribute from other XML NameValue elements, i.e. I have to distingiush
<mytag name="value"></mytag>
and
<mytag><name>value</name></mytag>.
In both cases the MbElement.getType() returns MbElement.TYPE_NAME_VALUE for the element "name".
Does anybody know how to do this???
Thanks,
Oli |

Hi kimbert,
I already found this method and I found out that the value returned by getSpecificType() for a XML attribute differs from the value returned for other NameValue elements. Unfortunately I can't find any documentation how the value can be interpreted. A constant like MbElement.TYPE_NAME_VALUE seems not to exist and the only thing I can do is to check whether the value returned by getSpecificType() is equal to MbElement.TYPE_NAME_VALUE or not.
Thanks,
Oli |

Hi again,
after doing some analysis I still have questions and don't understand how to determine if a MbElement is a XML attribute.
I have the following XML message:
| Code: |
<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<Data>
<Application name="App1">
<Customer>
<Name>Jim</Name>
</Customer>
</Application>
</Data> |
My Java Plug-in node doesn't know what the message domain is. The Java Plug-in node now calls
| Code: |
| aMbMessageAssembly.getMessage().evaluateXPath("/Data/Application") |
which returns the Application element. The first child of this element is the attribute.
And now I'm at the point where I must determine if this child is a XML attribute or not and for me it's not clear how to do this. For me the only possibility seems to be to do the following:
Check if the specific type of the element is MbXMLNSC.ATTRIBUTE. If so then we have an attribute. If not check the specific type with respect to the parser and do something like that:
| Code: |
if (theElement.getType() == MbElement.TYPE_NAME_VALUE) {
String elemParser = theMbElement.getParserClassName(); (that returns for example 'xmlns' in lowercases)
if (elemParser.equalsIgnoreCase(MbXMLNS.PARSER_NAME) || elemParser.equalsIgnoreCase(MbXML.PARSER_NAME)) {
// We have an attribute
}
} |
Is this the way the API is used or is there any other way to determine if an MbElement is an attribute?
Thanks,
Oli |

| Check the parser class name first. Until you know that, you cannot make any assumptions about the meaning of the field type. |
