Allow xpath searches

[mcuadros]

We should allow xpath queries at the dashboard to be able to test and debug queries. A nice to have could be having a small xpath editor, to help the creation.

Requires having a client-go, still in planning phase.

Is the current state of client-go capable of this?

[eiso]

I really like this idea!

@marnovo the python client just got this feature yesterday. I am not sure if the go client has it aswell.

[eiso]

It has been: https://github.com/bblfsh/client-go/pull/8/files

[zurk]

Yes, It will be really helpful. I need this feature.

[eiso]

Afaik @zork this has been implemented in both clients. @juanjux am I right?

[juanjux]

@eiso that's correct.
