nfo regarding databases to XML documents converter

Hi,
    Are there any XML tools which can covert a MIB table into a XML
document? If thats possible, please tell me from where i can get those tools
?

I think XML parsers operate normally om XML documents and Schemas can be
used to control the semantics of the XML elements/attributes given in the
XML Document.

So can some XMP parsers ( either SAX or DOM parsers )operate directly on
some databases treating them as virtual XML documents ? where can i get
those parsers ?

hoping to get soon some valuable info.

thanks and best regards
girish
