Very briefly, your application would implement the ContentHandler interface with something like: boolean processingInfoContent=false; StringBuffer infoText = new StringBuffer(); public void startElement(String uri, String localName, String qname, AttributeList atts) { if ((uri == null) && (localName.equals("info"))) processingInfoContent = true; } public void characters(char[] ch, int start, int length) { if (processingInfoContent) infoText.append(ch, start, length); } public void endElement(String uri, String localName)) { if ((uri == null) && (localName.equals("info"))) processingInfoContent = false; } One thing to remember here is that the whitespace contained in infoText will depend on whether you are using a validating parser. If so, and the content model of <info> is element-only (as opposed to mixed), then the "ignorable" whitespace will be reported in ContentHandler.ignorableWhitespace and infoText will be: "Metoday" . If not, and the parser chooses to ignore the DTD (if there is one), infoText will include all white space -- that is, it will be: " Me today " -- Ron Paul Johnston wrote: > > Please excuse my ignorance of XML. > > I've been using "XML" in various forms for a while now, but have been using DOM most of the time to do the work. > > I've just picked up SAX and it's brilliant for the right purpose, however... > > I want to be able to grab all of the character data for a specific tag (this is dummy XML and not very good dummy XML at that): > > <xml> > <mytag> > <info> > <doc> > <author>Me</author> > <date>today</date> > </doc> > </info> > <importantbit> > .... doesn't matter what's in here .... > </importantbit> > </mytag> > </xml> > > My question is (using JAXP) how can I retrieve all the text in the <info></info> tags?
