#include <CkXml.h>

void ChilkatSample(void)
    {
    CkString strOut;

    CkXml xml;
    bool success;

    // If autoTrim is true, then the content inside an leaf element is trimmed.
    // For example:
    bool autoTrim = true;
    xml.LoadXml2("<abc><xyz>  123   </xyz></abc>",autoTrim);
    strOut.append(xml.getXml());
    strOut.append("\r\n");

    // Output is:
    // (notice the SPACE chars before and after "xyz" are trimmed)

    // <?xml version="1.0" encoding="utf-8" ?>
    // <abc>
    //     <xyz>123</xyz>
    // </abc>

    // If autoTrim is false, then the content inside leaf elements are not trimmed.
    autoTrim = false;
    xml.LoadXml2("<abc><xyz>  123   </xyz></abc>",autoTrim);
    strOut.append(xml.getXml());
    strOut.append("\r\n");

    // Output is:

    // <?xml version="1.0" encoding="utf-8" ?>
    // <abc>
    //     <xyz>  123   </xyz>
    // </abc>

    // --------------------------------------------------------------------
    // The EmitCompact property controls whether XML is emitted indented (pretty-printed)
    // or compact.  For example:

    // Auto-trim + emit compact:
    autoTrim = true;
    xml.LoadXml2("<abc><xyz>  123   </xyz></abc>",autoTrim);
    xml.put_EmitCompact(true);
    strOut.append(xml.getXml());
    strOut.append("\r\n");

    // Output is:

    // <?xml version="1.0" encoding="utf-8" ?>
    // <abc><xyz>123</xyz></abc>

    // No Auto-trim + emit compact:
    autoTrim = false;
    xml.LoadXml2("<abc><xyz>  123   </xyz></abc>",autoTrim);
    xml.put_EmitCompact(true);
    strOut.append(xml.getXml());
    strOut.append("\r\n");

    // Output is:

    // <?xml version="1.0" encoding="utf-8" ?>
    // <abc><xyz>  123   </xyz></abc>


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
