10.6 Choosing a Parser


After choosing your programming strategy (SAX, DOM, XMLPULL, etc.), the next step in writing an XML application is to select a parser. There is no reason to write your own parser when so many excellent ones already exist. Some qualities to look for are API support, speed and efficiency, and robustness. Table 10-1 lists some of the best, although there are so many out there today that I could not hope to list them all.
