XML and Perl

Tree-Based XML Parser Modules

Tree-based XML parsing is one of two most popular ways of parsing XML, along with stream-based parsing, which was discussed in Chapter 3.The Document Object Model (DOM) standard defines a standard way to parse and represent the XML data in a tree-based parser. Tree-based parsers are also called in-memory parsers, because unlike stream-based parsers, which iterate over each piece of data and keep very minimal state information, tree-based parsers iterate over the XML document and create an in-memory representation of it for later use.You can then use Perl’s standard facilities to access the information in the data structure. The next few sections discuss non-DOM-compliant tree-based XML parsers.
