"Error while parsing SOAP XML payload: no element found" received when invoking Web Service

Question

Running PB 12.1 Build 7000.  Using Easysoap.  Error ""Error while parsing SOAP XML payload: no element found" received when invoking Web Service".  This error does not appear to be coming from the application code.  Noticed that there were some erroneous characters showing up within the header portion of the XML ("&Quot;").  Not sure where these are coming from.  When I do a find within the PB code for """" it gets located within two objects, whereas they both reference a "temp_xml_letter".  Not sure where or what temp_xml_letter resides???   The developer of this is no longer with us and my exposure to WSDL and Web Services is rather limited.  Need to get this resolved...please.
This is the result of the search.  Notice the extraneous characters ("""):

Answer 1

Maybe "extraneous" is an incorrect term.  Apparantly, based upon the writeup within Wiki, the parser I am using does not interpret the "&quot;"?  How do I find which parser is being utilized and how to control it?
<<<
If the document is read by an XML parser that does not or cannot read external entities, then only the five built-in XML character entities (see above) can safely be used, although other entities may be used if they are declared in the internal DTD subset.
If the document is read by an XML parser that does read external entities, then the five built-in XML character entities can safely be used. The other 248 HTML character entities can be used as long as the XHTML DTD is accessible to the parser at the time the document is read. Other entities may also be used if they are declared in the internal DTD subset.
