Hi Tamara,

I would like to know wether exists a way to filter a parent node by a child attribute.

E.g. : /jcr:root/site/Notícias//element(*,mtx:content) this query returns parent nodes, I would like to filter the query using mpt:fileGroup attribute from children nodes mtx:file.

I'm not sure I understand your node type model, but that would be something 
like:

/jcr:root/site/Notícias//element(*,mtx:content)[*/@jcr:primaryType = 'mtx:file' and */@mpt:fileGroup = 'some value']

or if mtx:file is the name of a node:

/jcr:root/site/Notícias//element(*,mtx:content)[mtx:file/@mpt:fileGroup = 'some value']
