I've got a couple of small example based ones but they don't really | deal with the more complex xml structures or how to handle recursion | within | xml.
JavaWorld (close enough) http://www.javaworld.com/javaworld/jw-10-2002/jw-1025-opensourceprofile. html Recursion is handled by specifying leading "*/tagName" in your path specifications. I used it in my CacheFilter implementation that allows you to setup trees of caches via the Composite Pattern. // from my ServletCacheRuleSet extends RuleSetBase public void addRuleInstances(Digester digester) { digester.addObjectCreate("*/cache", "type", CompositeServletCache.class); digester.addSetProperties("*/cache"); digester.addSetNext("*/cache", "addServletCache"); } // from my ServletCacheConfig (this.rules is a ServletCacheRuleSet) public ServletCache createCache(InputSource inputSource) throws IOException, SAXException { ServletCache cache = this.createCache(); Digester digester = new Digester(); this.rules.addRuleInstances(digester); digester.push(cache); digester.parse(inputSource); return cache; } For more complex examples, check out Strut's source code, Craig or whomever wrote all the configuration/setup procedures with Digester. -Jacob Hookom | | Cheers | | Simon | | Institut fuer | Prozessdatenverarbeitung | und Elektronik, | Forschungszentrum Karlsruhe GmbH, | Postfach 3640, | D-76021 Karlsruhe, | Germany. | | Tel: (+49)/7247 82-4042 | E-mail : [EMAIL PROTECTED] | | | -- | To unsubscribe, e-mail: <mailto:struts-user- | [EMAIL PROTECTED]> | For additional commands, e-mail: <mailto:struts-user- | [EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
