When I have whitespace in my xml parsed with XMLNSC, in the user trace I am seeing fields with whitespace field values like so:

(0x03000000)http://www.openapplications.org/oagis/9:Sender = '
'

I do not have retain mixed content checked anywhere.

Is this expected?

XMLNSC removes whitespace outside element values, not inside element values.

You likely have tags like
Code:
<ns1:Sender xmlns:ns1='http://www.openapplications.org/oagis/9'>
</ns1:Sender>


Where ns1 is just a sample, not intended to match your actual flow.

But the return is *inside* the element tag, not *outside*.

Jeff is correct. Mixed content occurs *between* tags, not inside them.

So here's the issue. An element that we were accessing before with XMLNS using (XML.Element) can now be either (XMLNSC.Folder) or (XMLNSC.Field) based on the whitespace content inside of the tags. Also the previous sibling can also be either an XMLNSC.Folder or XMLNSC.Field for the same reason.

So before where we had for XMLNS:
someRef.(XML.Element)*:*[2]

can now be for XMLNSC:
someRef.(XMLNSC.Folder)*:*[2]
OR
someRef.(XMLNSC.Field)*:*[1]
OR
someRef.(XMLNSC.Field)*:*[2]

Any suggestions on how to handle this simply?

I'd like to understand this in more detail. Please can you post the XML examples and the corresponding Trace node output for each case.

I am attempting to access the second XML element under the DataArea one. If the ServiceOrderValidation tag can occur as either XMLNSC.Folder or XMLNSC.Field I presume the same is true for the Process tag also.

Your xml example does not include the second instance of the ProcessServiceOrderValidation tag. The one which you have included contains mixed content, so it does not have a value.
I'm guessing that the second instance looks like this:
Code:
<Q2:ProcessServiceOrderValidation xmlns:Q2="http://www.mci.com/oagis/9">
</Q2:ProcessServiceOrderValidation>
In this case there are no child elements, so the whitespace between the tags is interpreted as the value of the element.

I can see that this makes it awkard to query the message tree in a consistent way. My suggestions would be ( in order of preference )
a) don't specify the type when querying this tag
b) use XMLNS, which does not build a compact tree

Note that b) will tend to increase heap usage, because each individual piece of mixed content will get put into the message tree.

No, that is not the second instance.

It seems to have mixed content in it and a value.

xml:
<Q2:ServiceOrderValidation>
<Q2:ID/>
<Q2:ActionCode/>
<Q2:Product>
<Q2:Code/>
<Q2:ProductOfferingID/>
<Q2:ActionCode/>
<Q2:CustomerParty/>
<Q2:BillToParty/>
<Q2:Service>
<Q2:ServiceID>
<Q2:PrimaryID>T-1-0-SIP</Q2:PrimaryID>
...etc.

I am specifically trying to migrate to XMLNSC so that rules out your option b. Also I need to specify the type to get this specific tag instead of some random whitespace.

I don't see anything in these examples that should produce Value nodes under the parent tag. You have asked the XMLNSC parser to discard mixed content, so the only children should be elements and attributes.
Maybe that code was left over from the XMLNS version of the ESQL?

Sorry that last example was a little misleading. There are tags before ServiceOrderValidation -- it is not the parent tag (see larger XML in earlier post).

No problem. But I still don't see why you need to specify the type. Can you please construct some simple XML fragments which exhibit the problems you are seeing. For each fragment, please state the problem you are encountering ( or better, quote some Trace node output ).

The tag name is variable. I just know that I need say the second xml element below the DataArea tag for instance. In the examples above that is the ServiceOrderValidation tag which I have shown can be either XMLNSC.Folder or XMLNSC.Field in the traces.

Previously with XMLNS using XML.Element was sufficient.

If I don't specify a type then I may end up with a reference to '\n'

I don't see how. If the '\n' is mixed content, then XMLNSC will discard it. If it is the value of the tag, the XMLNSC parser will create an XMLNSC.PCDataField, and put the value on the syntax element itself ( not as a child Value node ).
If you still think there's a problem, please post the XML fragment and the corresponding Trace node output.
