JSP to xml

[Singh Soorma]

How do I parse a jsp document [like basically an entry sign in page] to an xml documetn.

Does anyone have any ideas/tutorials?

Are you wanting to parse the output of the jsp page or the source of the jsp file? and what do you want to be in the xml document. give an example then i probably will be able to help more.

For XML parsing you can use the JAXP api's.

Normally, any serverside page such as ASP,PHP,JSP is executed at the server and the output is sent to the webbrowser in html format or watever the HTTPResponse is set to.

XML requires a structure so, even though html contains Tags, most of the time people dont end the tags.

XML needs to be well formed and u can use XSLT to do more stuff with it. Also u can use XPath to query XML document , but i only do xml in ASP.net so i dont know wat api functionality jsp provides.

Neways, like Khalsa said, If you are trying to create an XML document by running the jsp page then thats simple enough.

If you are trying to send an XML document to a jsp page for processing then thats probably doable.

Can you be more clearer please?

Ok its for a class assignmetn..

Wasn't sure of how to do it..

So you have a form has 10-15 elemetns, firstname,lastname,city address

and then you want to sumbit that form and it would create an xml document based on that data.

jsp form -- > xml

how would i do it ?

Thats pretty easy, your output will be an xml file.

you can store the string in the xml format like this

String xml_file = "<person_info>" +

"<name>" +

"<first_name>" + request.getParameter("first_name") +"</first_name>" +

"<second_name>" + request.getParameter("second_name") +"</second_name>" +

"</name>" +

....

.....

......

.......

......

"</person_info>";

and then just output the string like

<%= xml_file %>

Khalsa's reply is good, by string concatination u can build up a XML document.

Also if u set the resonsetype of the Response to "text/xml" then i think u can send the string to the browser and it will be displayed as an xml document, providing the xml document is valid.

i would suggest an alternative solution to this though.if you build a template xml file and then load that at runtime. then u can assign a value to each node>

this way you dont get that messy string handling that you end up doing in the above solution wont be needed.

So all u need is to build up an external xml file with the required structure.

Load it into memory using one of the api functions.

Assign values to the each node using the values captured from the form post.

And then do wat u want with the output, maybe save it to an external xml file.
