Parse SOAP XML Response

Code to parse a SOAP XML response.

This is the SOAP response parsed by the code below:

<?xml version="1.0"?>
<soap:Envelope
xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

<soap:Body xmlns:m="http://www.example.org/stock">
  <m:GetStockPriceResponse>
    <m:Price>34.5</m:Price>
  </m:GetStockPriceResponse>
</soap:Body>

// Needs #include <CkXml.h>

    CkString strOut;

    bool success;
    bool bFound;
    CkXml xml;

    //  Load the XML object with the SOAP response.
    //  The XML may be loaded from a file by calling
    //  LoadXmlFile, or directly from a string by calling
    //  LoadXml.
    success = xml.LoadXmlFile("soapResponse.xml");
    if (success != true) {
        strOut.append(xml.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    //  The quickest way to get a piece of data is w/ the
    //  ChilkatPath method.
    //  To get the content of the m:Price node:
    const char * strPrice;
    strPrice = xml.chilkatPath("soap:Body|m:GetStockPriceResponse|m:Price|*");
    strOut.append("Price = ");
    strOut.append(strPrice);
    strOut.append("\r\n");

    //  ------------------------------------
    //  Another way of doing it:

    //  Another way to get it is to navigate to the node.
    //  Navigate to soap:Body
    xml.FirstChild2();

    //  Navigate to m:GetStockPriceResponse
    //  You may call FirstChild2, or you may call GetChildWithTag2
    //  to get the Nth direct child having a given tag.
    //  In this case, get the 1st direct child having the tag
    //  "m:GetStockPriceResponse"
    //  (Indexing begins at 0, so the 1st occurance is at index 0.)
    bFound = xml.GetNthChildWithTag2("m:GetStockPriceResponse",0);
    if (bFound != true) {
        strOut.append("Did not find m:GetStockPriceResponse node.");
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    //  One more to go..
    bFound = xml.GetNthChildWithTag2("m:Price",0);
    if (bFound != true) {
        strOut.append("Did not find m:Price node.");
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    //  The content of the "m:Price" node is "34.5"
    strPrice = xml.content();
    strOut.append("Price = ");
    strOut.append(strPrice);
    strOut.append("\r\n");

    //  Restore the xml object's internal reference to the root
    //  of the XML document:
    xml.GetRoot2();

    //  ------------------------------------
    //  Another way of doing it:

    //  If you know that the node w/ the content you want to
    //  extract is uniquely tagged (i.e. no other node has the same
    //  tag), then search for the node having the tag:
    bFound = xml.SearchForTag2(xml,"m:Price");
    if (bFound != true) {
        //  Not found...
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    //  The content of the "m:Price" node is "34.5"
    strPrice = xml.content();
    strOut.append("Price = ");
    strOut.append(strPrice);
    strOut.append("\r\n");

    //  Restore the xml object's internal reference to the root
    //  of the XML document:
    xml.GetRoot2();

    //  ------------------------------------
    //  Another way of doing it:

    //  Again, assuming there is only a single node with the
    //  tag to be fetched:
    strPrice = xml.accumulateTagContent("m:Price","");
    strOut.append("Price = ");
    strOut.append(strPrice);
    strOut.append("\r\n");

    //  There are many other possible ways of doing the same thing...


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
