To use SAX to read XML, you create an instance of a parser object that is pointed to your document and to your application. While SAX reads the document, it calls the startElement (the start tag), endElement (the end tag), and characters (text data in between) as it goes. The SAX parser reads the XML le (also a DTD if it is present), and when it encounters something such as an element, it generates an event. On recognition of such an event, your program can register with the parser as a listener by implementing certain interfaces. The SAX parser then calls certain methods, which you have overridden to do what you need to do in response to the event. Although the SAX parser organizes its events a bit di erently, the situation is similar to an Abstract Window Toolkit (AWT) button generating ActionEvents when clicked. Then an interested class implements an ActionListener and overrides the callback method actionPerformed. SAX events, unlike AWT events, come in an ordered sequence as the XML le is read in. Given the tree structure of the XML le, the parser generates events in a depth- rst order. Furthermore, because the events are triggered on the y as the XML le is read in, you only get one chance to grab an event as it goes by. You must do something to capture relevant information at the point at which it arrives, or the information is lost unless you parse the entire le again. This is in contrast to the DOM parser, which reads the entire document in, storing it in its tree structure in memory, and then waits for your program to analyze it. The steps are 1. 2. 3. 4. Obtain a SAX parser for your system (such as Xerces from Apache). Provide a document handler (usually a Java class). Customize error handling for the software used (also Java-based). Use a validating parser for the XML (Xerces again).

To understand how an event-based API works, consider the following sample document: < xml version="1.0" > <doc> <greeting>Hi everyone!</greeting> </doc> An event-based interface will break the structure of this document into a series of linear events: start document start element: doc start element: greeting characters: Hello everyone! end element: greeting end element: doc end document

function has a speci c intention and should be chosen only if node context is to be interpreted and returned. This example of the function id() will demonstrate how a node set function can be used to access an element either by name or by a combination of name and path. The function id() is de ned by the W3C as node-set id(object). We can return a title element by calling id() as id("title") This will return, or select, the element with the unique ID of title. Alternatively, we can select an object o set from the speci ed title element using the statement id("title")/child::subtitle[position()=4] which will return the fourth child subtitle of the element title as a speci c element and relative position. The node set functions allow us to access the values of namespace-uri() of the document or the context node if left empty (default). String functions typically are used for operations on strings, such as converting a number to a string (for nonpresentation purposes), or testing the values of a string (or substring) and returning a true or false (Boolean) value. The function string() will attempt to convert a number to a string with the following results:        NaN is returned if the value is not a number. 0 from positive zero. 0 from negative zero. In nity from positive in nity. In nity from negative in nity. Integer form if the value is an integer. Decimal form if it is not an integer, including the decimal point with at least one digit before and one digit after the decimal point.

The string() function will try to convert to one of the four basic types and failing that will convert to a string in a way that is consistent with that type. However, most of the time the result will fall into one of the four basic datatypes. String functions are typical of most programming or scripting languages with no real surprises. The versatility, or scope, of these functions does not begin to approach that of string functions found in Perl, PHP, or any language that is strong in regular expressions. However, remember that most of the functionality of XPath (and most of XML) is still developing and has a long way to go in its evolution. Table 6-3 shows a list of string functions and touches on the syntax and use of these functions. As always, refer to the o cial W3C specs for full details.

string translate(string, string, string) Returns the rst string with characters contained in the second string replaced by the characters in the same positions in the third string. This is a positional replacement, so characters in the third string may be repeated. If there is no corresponding character, based on position, in the third (replacement) string, then the character is removed. If a character in the rst string is not found in the second, then it is ignored. The case of the replacement character is maintained. Returns the rst string with leading and following white space stripped, as well as multiple spaces being replaced by a single space. Returns true if rst argument string contains second argument string; else, returns false.
