How to parse/process this XML (DOM or SAX)?
Hello all,
Here is a set of XML nodes that I need to process.
<message>
<text>
The meeting is scheduled <secure>at 1600hrs</secure> and the attendees will be VP engineering, VP finance, VP products.
</text>
</message>
In the above XML, when I use a DOM parser to get the text of the tag <text> I get all the characters till <secure>.. However, I do not get the text after the </secure> .
What am I missing? Isnt this XML valid? It sure does look a lot like an XHTML. In which case I suspect the XML is valid.
Please advise.
Thanks and Cheers

The <text> node contains two separate text-type nodes and one element-type node as follows:
1. "The meeting is scheduled"
2. <secure>at 1600hrs</secure>
3. "and the attendees will be VP engineering, VP finance, VP products."
If you want to concatenate all the text content inside the <text> node to one sentence, you could use this:Node text = <the node named "text">
String sentence = text.getTextContent();
The "sentence" variable stores the following string:The meeting is scheduled at 1600hrs and the attendees will be VP engineering, VP finance, VP products.
