Parsing an XML string into a kXML Element

Question

I'm writing an Android app that connects to a SOAP webservice using kSOAP2, and I have a kXML element where I would like to inject a child based on an XML string I got from elsewhere (a REST API). I have the following code:

Element samlHeader = new Element().createElement("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", "Security");
samlHeader.setPrefix("wsse", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
samlHeader.setPrefix("wsu", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");

String samlTokenString = ...; //I got this from elsewhere
Element samlTokenElement = ...; //I don't know how to build this
samlHeader.addChild(Node.ELEMENT, samlTokenElement);

So I'm trying to figure out how to build my Element based on the XML string I'm getting from elsewhere.

This is the solution that we ended up implementing:

try {
    KXmlParser parser = new KXmlParser();
    parser.setInput(new StringReader(samlTokenString));
    parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, true);

    Document samlTokenDocument = new Document();
    samlTokenDocument.parse(parser);
    samlHeader.addChild(Node.ELEMENT, samlTokenDocument.getRootElement());
} catch (XmlPullParserException e) {
    Log.e(TAG,"Could not parse SAML assertion", e);
} catch (IOException e) {
    Log.e(TAG,"Could not parse SAML assertion", e);
}

We're still validating if it produces the right result but it seems to work.
