[Fedora-suds-list] Problem when embedding an XML element into the soap message

Hi, I'm building a SOAP client, and I want to embed some XML data in the soap message. The XML data is already in an external XML file. I used the method introduced in the "Tips & Tricks / Including Literal XML" section. The XML file is first parsed, and a suds.sax.element.Element is obtained. Then the RPC is made with the Element as the argument. However, the resulting SOAP message only contains the root node of the XML. For example, if I use the "query" example in that section to construct the XML data to be embedded, the only embedded data is an empty <query/> tag. In the log information suds printed out, it did contain all the data in the query tag. Do you have any suggestions on where the problem might be? Thanks, Bin
