RPC::XML::Parser - A container class for XML::Parser


    use RPC::XML::Parser;
    $P = new RPC::XML::Parser;


The RPC::XML::Parser class encapsulates the parsing process, for turning a string or an input stream into a RPC::XML::request or RPC::XML::response object. The XML::Parser class is used internally, with a new instance created for each call to parse (detailed below). This allows the RPC::XML::Parser object to be reusable, even though the XML::Parser objects are not. The methods are:


Create a new instance of the class. Any extra data passed to the constructor is taken as key/value pairs (not a hash reference) and attached to the object.

parse { STRING | STREAM }

Parse the XML document specified in either a string or a stream. The stream may be any file descriptor, derivative of IO::Handle, etc. The return value is either an object reference (to one of RPC::XML::request or RPC::XML::response) or an error string. Any non-reference return value should be treated as an error condition.


The constructor returns undef upon failure, with the error message available in the global variable $RPC::XML::ERROR.


This is part of a reference implementation in which clarity of process and readability of the code take precedence over general efficiency. Much, if not all, of this can be written more compactly and/or efficiently.
