<H1> 5. The DOM module </H1>
<!--docid::SEC14::-->
<P>
</P><P>
A default SAX implementation is provided in the tree_readers file, through
its Parse function. This reads an XML stream and creates a tree in memory.
The tree can then be manipulated through the DOM module.
</P><P>
Note that the encodings.ads file specifies the encoding to use to store
the tree in memory. Full compatibility with the XML standard requires that
this be UTF16, however, it is generally much more memory-efficient for European
languages to use UTF8. You can freely change this and recompile.
</P><P>
What is the Document Object Model?
</P><P>
The Document Object Model is a platform- and language-neutral interface that will allow programs and scripts to dynamically access and update the
content, structure and style of documents. The document can be further processed and the results of that processing can be incorporated back into the
presented page. This is an overview of DOM-related materials here at W3C and around the web.
</P><P>
Why the Document Object Model?
</P><P>
"Dynamic HTML" is a term used by some vendors to describe the combination of HTML, style sheets and scripts that allows documents to be
animated. The W3C has received several submissions from members companies on the way in which the object model of HTML documents should be
exposed to scripts. These submissions do not propose any new HTML tags or style sheet technology. The W3C DOM WG is working hard to make
sure interoperable and scripting-language neutral solutions are agreed upon.
</P><P>
The DOM (Document Object Model) is a set of subprograms to create and
manipulate XML trees in memory.
</P><P>
You can create such a tree through the tree_readers.Parse function.
</P><P>
Only the Core module of the DOM standard is currently implemented, other
modules will follow.
