Re: [xmlblaster] get call fix

[Michele Laghi <laghi at swissinfo.org>]

Hi Chris,

the statement:

*[((//metadata/SpecificObjectData/tst_meta/type='CLASSINFO') ....]

would take all elements (since you set * on the left of the square 
brackets) and submit the XPATH expression inside the square brackets. 
The later would give back a boolean true or false. If the expression 
returns true, then the COMPLETE element for which the statement was true 
is added to the result tree. In your case you would get the complete 
xmlBlaster element plus the complete key element and the complete 
metadata element as the result tree.

So the solution here is to have a more selective location path on which 
to submit the square bracket expression (i.e. filter away already from 
the beginning the root element 'xmlBlaster' which we know contains a lot 
of system specific 'trash'). Specifying /xmlBlaster/key/metadata[...] 
does exaclty that.
