RPC::XML::Parser::XMLLibXML3pm

Usage

    # This class should rarely (if ever) be used directly:
    use RPC::XML::ParserFactory 'XML::LibXML';
    ...
    $P = RPC::XML::ParserFactory->new();
    $P->parse($message);

Overview

This class implements the interface defined in the RPC::XML::Parser factory-class (see RPC::XML::Parser) using the XML::LibXML module to handle the actual manipulation of XML.

Subroutines/methods

This module implements the public-facing methods as described in RPC::XML::Parser:

new [ ARGS ]

The constructor only recognizes the two parameters specified in the base class (for the RPC::XML::base64 file-spooling operations).

parse [ STRING | STREAM ]

The parse() method accepts either a string of XML, a filehandle of some sort, or no argument at all. In the latter case, the return value is a parser instance that acts as a push-parser (a non-blocking parser). For the first two types of input, the return value is either a message object (one of RPC::XML::request or RPC::XML::response) or an error.

parse_more STRING

(Only callable on a push-parser instance) Parses the chunk of XML, which does not have to describe a complete document, and adds it to the current running document. If this method is called on a parser instance that is not a push-parser, an exception is thrown.

parse_done

(Only callable on a push-parser instance) Finishes the parsing process and returns either a message object (one of RPC::XML::request or RPC::XML::response) or an error (if the document was incomplete, not well-formed, or not valid). If this method is called on a parser instance that is not a push-parser, an exception is thrown.

Diagnostics

All methods return some type of reference on success. The new and parse methods return an error string on failure. The parse_more and parse_done methods may throw exceptions, if the underlying XML::LibXML parser encounters a fatal error.

External entities

As of version 1.15 of this module (version 0.75 of the RPC::XML suite), external entities whose URI is a "file:/" scheme (local file) are explicitly ignored. This is for security purposes.
