WRT XML Parser

[bhanuchandar.k]

Hi,
Is there any xml parser available for widgets Like Kxml parser for j2me ? I want to parse the xml . How do I do that?

Hi Bhanu,

if you want to get the XML structure of a document retrieved from an XMLHttpRequest call, you can directly access its responseXML object, containing the response complete XML tree.

To parse an XML got in another way, you can:

1) take the XML content as plain text
2) create a fake (hidden) DIV
3) set the innerHMTL property of the created div to the XML content

Doing this way, you'll be able to access the complete XML structure by simply traversing the DIV DOM structure.

Hope it helps,
Pit

Hi jappit,

Hi,

The response object from the XmlHttpRequest has these properties

// String version of data returned from server
XmlHttpResponse.responseText

// DOM-compatible document object of data returned from server
XmlHttpResponse.responseXML

responseXML itself is a DOM object, it's ready parse. But in case of responseText, use the method that @jappit mentioned on his reply.

Thanks,
Raghava

Hi Bhanu,

just follow the good tips given by Raghava.

For some other useful infos and code, take a look here:

Just fetch the data with XHR and you can get the parsed DOM tree with the responseXML property of the XMLHttpRequest object. I.e. you don't need to explicitly parse anything - it's done for you.
