Eric Armstrong In This Chapter Writing a Simple XML File Defining the Root Element Echoing an XML File with the SAX Parser Adding Additional Event Handlers Handling Errors with the Nonvalidating...

Let's start out by writing up a simple version of the kind of XML data you could use for a slide presentation. In this exercise,...

After the declaration, every XML file defines exactly one element, known as the root element. Any other elements in the file are contained within that...

In real life, you are going to have little need to echo an XML file with a SAX parser. Usually, you'll want to process the...

Besides ignorableWhitespace, there are two other ContentHandler methods that can find uses in even simple applications: setDocumentLocator and processingInstruction. In this section of the tutorial,...

This version of the Echo program uses the nonvalidating parser. So it can't tell if the XML document contains the right tags, or if those...

The next thing we want to do with the parser is to customize it a bit, so you can see how to get information it...

After the XML declaration, the document prolog can include a DTD, which lets you specify the kinds of tags that can be included in your...

In the last section, you defined a rudimentary document type and used it in your XML file. In this section, you'll use the Echo program...

The DTD you've defined so far is fine for use with the nonvalidating parser. It tells where text is expected and where it isn't, which...

This section contains no programming exercises. Instead, it discusses the options for referencing binary files like image files and multimedia data files. 5.Using a MIME Data...

By now, you have done a lot of experimenting with the nonvalidating parser. It's time to have a look at the validating parser and find...

Just as a general entity lets you reuse XML data in multiple places, a parameter entity lets you reuse parts of a DTD in multiple...

This section uses the Echo program to see what happens when you reference xhtml.dtd in slideshow.dtd. It also covers the kinds of warnings that are...

You saw earlier that if you are writing text out as XML, you need to know if you are in a CDATA section. If you...

In this section of the tutorial, we'll carry on a short discussion of the two remaining SAX event handlers: DTDHandler and EntityResolver. The DTDHandler is...
