Re: [xsl] XML access control by custom ID

2010-03-10 00:58:08
In the quoted example "administrator" and "anybody" are user roles.

In other words. I have 2 XML files. One containing data and another
containing user rights to this data. Data is marked with domain unique
id's to allow my system to trace usage of this data. The user rights
(or access control) file contains the id's of data items and the
rights that users have against these data items.

What I need is twofold:
1. filter the data based on what is visible to the user group
2. include the user rights as attributes on this filtered data

I have been struggling with this for a long time and cannot find a
good solution.

<a some_attributes="xyz" my_id="1">

</a>
<b attribute="xxx" my_id="2">
  ABC
</b>

and the access controlling information is (in a separate file):
   <userroles>
<administrator>
 <read>
    <my_id>1</my_id>
    <my_id>2</my_id>
</read>
 <write>
    <my_id>1</my_id>
    <my_id>2</my_id>
 </write>
</administrator>
<anybody>
 <read>
    <my_id>1</my_id>
 </read>
 <write>
    <my_id>1</my_id>
 </write>
</anybody>
    </useroles>


For this I need a stylesheet to filter and combine the data and access
rights indicated by the access control data set. As an example, if I
were to use the previous 2 xml files as input given a parameter of
"anybody", then the resulting XML should  look like:

<a access="read; write" some_attributes="xyz" my_id="1">
  123
</a>

Well, and how do <administrator> and <anybody> come into play here?
