I was struggling with this message(XML) with MQRFH2 Header.
I have tried the MRM Header, the drawback is that you got to choose a schema, which makes it less flexible. Also the parsers being selected at runtime (printed in the mqsitrace log) are not consistent! Still puzzling.
Setting parser as BLOB in the MQInput node solved my issue. Without making any further message format conversion, you can read the xml using XMLNSC parser anytime anywhere.
