read the values from xml using java

[vinoth Robert]

hi,

this is my problem.

I have a XML file. I don't know the node(tag) names in that XML file.

i need to read the node values.

How to do this. I know to read values by giving the node name.

for example

element.getElementsByTagName("name");

help please..

Hi,
Can you try the below steps -
1. Parse the xml document and build a DOM
2. Get the document element (first element / top element) of the document using Document:getDocumentElement() method
3. Get the child nodes of the document element using getChildNodes() method which will return a node list
4. Iterate through the list and for each node convert it to an Element (just do (Element)nodeList[i]) and get its attribute ( i think at least you know the attr name?)

If I read it correctly, the desired content is not an attribute but the element text content instead. Which is where either the getTextContent() method can help, or if that's not available (there was a thread about that just recently) check the nodes that are Text. Because the nodes do not need to be Element nodes; Text, ProcessingInstruction, Comment - those are nodes as well.

Another possibility is to not use the org.w3c.dom package but use a library (like JDOM) instead.
