not able to parse tags using sax parser
Question
Following is my xml:
<Body>
<tag1 xmlns=""> <innerTag></innerTag> </tag1>
</Body>
The problem is that I am not able to get the string inside <tag1></tag1> , that is <innerTag></innerTag> . Following is my logic:
public void startElement(final String uri, final String localName,
final String qName, final Attributes attributes)
throws SAXException {
if ("tag1".equalsIgnoreCase(qName)){
inTag1 = true;
System.out.println("start");
}
}
public void endElement(final String uri, final String localName,
final String qName) throws SAXException {
if ("tag1".equalsIgnoreCase(qName)) {
System.out.println("end");
inTag1 = false;
}
}
public void characters(final char[] ch, final int start, final int length) {
if (inTag1) {
System.out.println("@@@" + new String(ch, start, length));
}
}
}
But it is giving me empty output. Can anyone help.

In your comment to UVM's answer you wrote
Actually inner tag is a kind of xml inside this xml. So I want that as a whole
There is no way to tell the SAX parser to not process all of the XML inside an element and return the entire contents as a string. Essentially, you have two options:
- reconstruct the XML string, by listening out to all of the SAX events and building the XML string up yourself, or
if you're in control of the XML documents you're attempting to parse, changing the format of them to something like
<Body> <tag1 xmlns=""><![CDATA[ <innerTag></innerTag> ]]></tag1> </Body>

You need to check "innerTag" intead of "tag1"
if ("innerTag".equalsIgnoreCase(qName)){
inTag1 = true;
System.out.println("start");
}
Basically your innerTag is a child element of tag1.So SAX parser keep on parsing because for it, it is till a valid XML element.
