Conversion of tiny bit of c# code to javaScript

I have some c# code which fetches SQL into a Dataset and then uses this to set textbox controls on a page. It also uses a similar method to do the reverse e.g. take the controls and put their data into a dataset. What I want to do is replicate this code in JavaScript.? Now I presume there is no Dataset object in Java so it would need to produce equivalent XML...which I can then parse back into a dataset. Below is an example of the XML produced from the Dataset...Note that controls are Dynamically created so..the XML will need to change accordingly. <BusinessObject> ? <Definition_x0020_Table> ? ? ? <BusinessObjectID>35</BusinessObjectID> ? ? ? <Name>Test</Name> ? ? ? <Description>Primary Business Object</Description> ? ? ? <IsPrimary>1</IsPrimary> ? </Definition_x0020_Table> ? <Test> ? ? ? <TestID>45</TestID> ? ? ? <Name>Test Object 2</Name> ? ? ? <System>false</System> ? ? ? <CreatedDate>2009-11-02T00:00:00+00:00</CreatedDate> ? ? ? <CreatedBy>test</CreatedBy> ? ? ? <ModifiedDate>2009-12-14T13:47:25.127+00:00</ModifiedDate> ? ? ? <ModifiedBy>Admin</ModifiedBy> ? ? ? <Version>1</Version> ? ? ? <Deleted>false</Deleted> ? ? ? <StatusID>22</StatusID> ? ? ? <Test_Currency>4000.0000</Test_Currency> ? ? ? <TestURL>0</TestURL> ? ? ? <ActiveScreenID>3</ActiveScreenID> ? ? ? <FixedComboID>32</FixedComboID> ? ? ? <BusinessComboID>35</BusinessComboID> ? ? ? <SimpleCombo>Image</SimpleCombo> ? ? ? <Order>41</Order> ? ? ? <FieldID>919</FieldID> ? ? ? <TestFormula>TEST FORMULATest Object 2</TestFormula> ? </Test> </BusinessObject>
