   I am trying to obtain an attribute value from a response message. I've
   been using the exchange rate example and have understood what's
   happening with the call-back.



   I thought the attrs parameter in the call-back interface would provide
   access to the current element attributes, but when I look  at it with
   debug it's all null pointers. What should it contain?



   I found some other responses regarding %paddr(GetInnerDoc) but am a
   little confused because it uses http_parse_xml_stmf. I thought it
   would be easier to use a pointer to the string to search for the
   desired attribute. After all the ds has a pointer to buf and a length?



   I presume that that technique was when a program needs to obtain sub
   elements in a particular branch?



   I found http_parse_xml_string() in the httpapi_h file and that looks
   like it uses the pointer, but now I don't know how to find the
   attribute!



   Should I be doing a scan of that string looking for the specific
   attribute name and then obtaining the value?



   Thanks again.
