[xml] Can xmllint format with in-place file saving?

[mruhrbach aim com]

Hello list,

I run xmllint to format my XML file: xmllint --format file.xml

The output goes to stdout, so I capture it in a file: xmllint --format 
file.xml > formatted.xml

Now I replace the old with the new: mv formatted.xml file.xml

Question: can this be done in one step? I imagine something like: 
xmllint --format --in-place file.xml, as is known form sed.

Thanks!
