[erlang-questions] Best Erlang approach for sending and parsing XML via HTTP

Sat Nov 17 18:27:46 CET 2012

Hi list

I need to interface with an SOAP service, and i would like to keep it as
simple as possible, so basically i would like just to send the XML via HTTP
and parse the response, what is the best approach for this with Erlang?

Could i use httpc, or should i go for the SOAP client via Yaws?

The request i need to send is:

-------------------------
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Header />
    <Body>
        <ns:Login xmlns:ns="http://schemas.ericsson.com/cai3g1.1/">
            <ns:userId>"xxxx"</ns:userId>
            <ns:pwd>"xxxx"</ns:pwd>
        </ns:Login>
    </Body>
</soapenv:Envelope>
-------------------------

And i need to get the sessionId in the response:

-------------------------
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="
http://www.w3.org/2001/XMLSchema" xmlns:ns="

http://schemas.ericsson.com/cai3g1.1/" xmlns:ns4="
http://schemas.ericsson.com/cai3g1.2/">
    <SOAP-ENV:Header></SOAP-ENV:Header>
    <SOAP-ENV:Body>
        <ns3:LoginResponse>

<ns3:sessionId>84c3646484c36464000000001353168328092</ns3:sessionId>
            <ns3:baseSequenceId>5584289115023516944</ns3:baseSequenceId>
        </ns3:LoginResponse>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
