The MegObjectExamplePlugin demonstrates the use of WBI's new MegObject API. MegObjects enable Megs to pass certain kinds of objects rather than simply streamed binary or character data. This ability is used in this example so that all Megs can work on the same Document Object Model (DOM). This eliminates the need for continual parsing and reparsing of the stream.

With Microsoft Data Access Components (MDAC) version 2.1 and later, the ADO Recordset object supports the feature to persist an ADO recordset in XML format to a file on the disk by using the Save method of the ADO Recordset object. This data can then be loaded into the Microsoft XML Document Object Model (DOM) from the persisted file.

DOM models a standard XML parser output (parse tree).

The Simple API for XML (SAX) is just one approach to parsing XML. An alternative approach is the Document Object Model (DOM), which builds a data tree in memory for easier, non-sequential access to XML data fragments. In this article, find out how to combine the Java-based Xerces parser with the DOM to create simple Java/XML applications.If you're at all familiar with XML programming, you'll be aware that there are two basic approaches to parsing an XML document. The Simple API for XML (SAX) is one; it parses an XML document in a sequential manner, generating and throwing events for the application layer to process as it encounters different XML elements. This sequential approach enables rapid parsing of XML data, especially in the case of long or complex XML documents; however, the downside is that a SAX parser cannot be used to access XML document nodes in a random or non-sequential manner.

In this concluding article of a two-part series, use your knowledge of DOM processing with Xerces to construct simple Web applications based on Xerces, XML and JSP. Examples include transforming an XML file to HTML via Xerces and dynamically generating an XML document tree from a MySQL database.The first part of this article discussed XML parsing with the Xerces DOM parser, explaining the basics of creating and traversing an XML DOM tree. It also illustrated the theory with practical (and not-so-practical) examples, using parser interfaces and callbacks to to construct some simple Java programs.

Generators are a very powerful new language feature of Python 2.2. In this tip, Uche Ogbuji presents a set of techniques for using generators for fast and lucid XML processing patterns in Python.

This tutorial is intended for developers who wish to extract data from a database and insert it into XML files so that it can be processed in some way, usually by transforming it into HTML using an XSL file.

The DOM API is large and quite complex.

The xml.dom.minidom module is essentially a DOM 1.0-compatible DOM with some DOM 2 features (primarily namespace features).

The xml.dom.minidom module is essentially a DOM 1.0-compatible DOM with some DOM 2 features (primarily namespace features).

xml.dom.minidom is a light-weight implementation of the Document Object Model interface. It is intended to be simpler than the full DOM and also significantly smaller.

XML application developers usually have to contend with the complexities of SAX or the inefficiencies of DOM. This tip shows how a pull approach to DOM can effectively bridge the gap between the two by offering simple, efficient parsing.

The definition of the DOM API for Python is given as part of the xml.dom module documentation. This section lists the differences between the API and xml.dom.minidom.

This function inserts the new node newnode right before the node refnode. The return value is the inserted node. If you plan to do further modifications on the appended child you must use the returned node.

xml.dom.minidom is a light-weight implementation of the Document Object Model interface. It is intended to be simpler than the full DOM and also significantly smaller.

One of the most frequently asked questions we get concerning XML and Visual Basic is about how to work with the Microsoft XML Parser (MSXML.DLL) that comes with Internet Explorer 5. It's fine knowing how to write XML, but one needs to know how to read and manipulate an XML file.
