Hi,

I am trying to convert a BLOB to XMLNSC and getting this exception while parsing. Trace details below -

The API returns an XML as a BLOB in the response. I am trying to parse it to get the xml message for further conversions.
I can see that the xml has a character (Unicode: 0x1f) which seems to be invalid for XML1.0 but how do I check whether the provider is constructing XML 1.0 or 1.1?

Any leads would help. Thanks!

I am really surprised you did not catch on earlier on this but your BLOB is not XML. First your BLOB is a hex representation of binary data.
However that binary data is not XML.
X'1f8b0800000000000003...' binary is not part of any XML I know of ... Unless it is a fragment of an xml document representing a hexbinary element and then your BLOB might represent that hexbinary content...
Note the hex 00 values. Those are not character values...

Have fun

I am surprised too

I made some transformation changes and looks like the code is working now...and I am getting a proper XML using RCD node without having to parse in ESQL. The RCD was not working before though.

Thanks for making time to give a look. Appreciate the reply!
