Re: [schema] which assertions can't you express ?


php xml parser section id
Did anyone consider using XSLT to transform this into a more usable XML
format?

e.g.
<reportDefinition>
    <officers>
     <secretary>
           <name />
            <appointmentDate>
             <dateOfBirth />
. . .

Then the XSD would be much easier to create, since the previous values are
now element names.

I know it is an extra step, but the original XML looks like another of those
key/value pairs created to make it easy to get into an RDBMS or some other
table mechanism.  and since there are not a lot of XPATH generators, the
XPATH statements in the new structure would be much simpler and more obvious
to code by hand.

Just a thought . . .
