Hi,

A program that interprets the contents of an XML file and determines what to do with the input is a parser program.

There are different kinds of parsers (SAX / DOM).

Hi Dakota,

The XML Parser for PL/SQL parses an XML document (or a standalone DTD) so that it can be processed by an application. Library and command-line versions are provided supporting the following standards and features:

> DOM (Document Object Model) support is provided compliant with the W3C DOM 1.0 Recommendation. These APIs permit applications to access and manipulate an XML document as a tree structure in memory. This interface is used by such applications as editors.

> SAX (Simple API for XML) support is also provided compliant with the SAX 1.0 specification. These APIs permit an application to process XML documents using an event-driven model.

> Support is also included for XML Namespaces 1.0 thereby avoiding name collisions, increasing reusability and easing application integration.

A parser is a sintactic analyser that checks if the XML document format is correct or not based on several conditions. You can use a parser in your own applications if you like to work with XML documents. Some of them checks the format and the whole document with a DTD and some others do not. The last ones checks if the tags are correctly closed or even if there is only one main tag at the beggining of the document.

One example of the last one is

<?xml version="1.0"?>

<mydoc format="simple">

<mytitle>titulo</mytitle>

<main someatt="someval">

<para>un parrafo</para>

<para>segundo parrafo</para>

<para>tercer parrafo</para>

</main>

</mydoc>

The result would be

mydocformat: simple

mytitle

titulo

mainsomeatt: someval

para

un parrafo

para

segundo parrafo

para

tercer parrafo

I hope this could be grateful
