[augeas-devel] Square lens update

[Francis Giraldeau]

Hi, 

The square lens is now working for recursive lens. This way, XML
documents can be processed. 

The patch is on square2 branch on github: 

http://github.com/giraldeau/augeas/tree/square2

There is one gotcha. With nonrecursive lens, then mismatch tags are
detected. But, with recursive lens, since the parser doesn't know what
the close tag should be, it can accept invalid documents. In the put
direction, the modified document will be "fixed" in some ways, because
the close tag will be copied from the open tag (the key). This is an
example of the behavior. The "a" element is never closed, it is
accepted, and in the put direction, the tag is closed appropriately. 

test xml_rec put "<a><b></b></c>" after clear "/x" =
"<a><b></b></a><x></x>"

We may have to analyze the resulting parse tree to validate square
elements. 

I'm working on a generic XML lens and on the httpd config. 

Have a nice day, 

Francis
