In One of my integration my source system is sending an XML with blank/null tag values and the data is send as . After enriching the message at webMethods end the while converting it to a XML string the blank/null tag is changed as which the target system is not able to recognize it. It is throwing an error and at the target system they want the blank/null tag to be .
As a work around we are setting the blank tag with space and while converting it is getting converted properly. Let me know if there is any direct way to solve this issue.
