xmlrpc::decode_value (private)

 xmlrpc::decode_value node

Defined in packages/xml-rpc/tcl/xml-rpc-procs.tcl

Unpack the data in a value element. Most value elements will have a subnode describing the datatype (e.g. <string> or <int>). If no subnode is present, then we should assume the value is a string.

Parameters:

node (required)

<value> node that we're decoding

Returns:

Returns the contents of the <value> node. If the value is a <struct> then returns the data in a TCL array. If the value is an <array> then returns the data in a TCL list.
