[Exist-open] XUpdate with SAX

[Arek S. <dev...@kr...>]

Hi,

Is it possible to send XML Fragments or XUpdate documents with SAX to eXi=
st? I=20
found in XUpdateQueryService only method which take String.

All XML documents in my program are loaded to Java as beans with XMLBeans=
=20
(http://dev2dev.bea.com/technologies/xmlbeans/index.jsp) binding framewor=
k.=20
Then they are changed by user, I save them with code similar to this:

XMLResource r =3D (XMLResource) col.getResource(xmlName);
ContentHandler contentHandler =3D r.setContentAsSAX(); =20
document.save(contentHandler, (LexicalHandler) contentHandler);
col.storeResource(r);

The documents are not very big (currently with test data 5-20 KB), but I =
can=20
image they could grow then program start to be used in real (max to 100 K=
B).=20
Then any change happen I know exactly the XPath to element or attribute, =
so I=20
was thinking of using XUpdate to change only this single place in documen=
t.

If I understand how this works, I will need to build XUpdate document as=20
String (or convert some Object representing it to String) and send it wit=
h=20
XUpdateQueryService. Then eXist need to parse this String, and do the job=
.
As I run eXist in embedded version in same JVM, I don't see it as good=20
solution for me. Probably I will not get it quicker comparing to current=20
solution, as documents are not very big.

It will be great if in XUpdateQueryService I could specify document, and =
XPath=20
to element, and send XML Fragment with SAX in similar way I do it now wit=
h=20
XMLResource.

Is anything like this possible or you plan something similar in the futur=
e?
Maybe there is some other technique to updated documents I could use?

Best regards
Arek
