parseSOAP: Parse XML message
In sckott/SSOAP: Client-side SOAP access for S

This is a convenience function to parse the SOAP message returned from a server and retrieve the payload of the message as an XML tree in S.

1 2	parseSOAP(xmlSource, header = FALSE, reduce = TRUE, ..., fullNamespaceInfo = TRUE)

`xmlSource`	an string giving the name of an file or URL containing the XML content, or a string containing the XML content itself.
`header`	ignored
`reduce`	a logical value indicating whether to return the top-most XML node of the Body or to return the entire XML tree read from `xmlSource`. If this is true, we find the Body node and return its first child.
`...`	arguments that are passed directly to `xmlTreeParse` without being processed by this function.
`fullNamespaceInfo`	a logical value that is passed on to `xmlTreeParse` when parsing the SOAP response This controls how the namespace information on each XML node is represented, with `TRUE` causing the prefix and URI to be included rather than just the prefix.
