Re: [Exist-open] XMLSH for Exists

[Dan M. <dan...@gm...>]

Hello David,

Thanks looking into getting XMLSH to run on eXist.  I am looking forward to
being a beta tester!

I have been a big fan of the concept of building libraries of small reusable
components of XML filters that can work together like UNIX pipes for a long
time. I frequently need a small XQuery "node filters" that can be chained
together to cleanup incoming XML data.  This is similar to the goals of
XProc project and has been something that many people could use.  So your
work on an eXist version XMLSH seems like a great step in this direction.

If you are looking for samples of XQuery functions that we could
chain-together from a command-line I hope we look at the "Node Filters"
Wikibook article here:

http://en.wikibooks.org/wiki/XQuery/Filtering_Nodes

These XQuery functions could provide the basis for a small series of
shell-like commands for filtering XML using XQuery.

Let me know when you need help beta testing!

- Dan
