Hi,
Please consider the below case:
Document 1:
<doc>
<item name="fruit" value="apple"/>
<item name="color" value="red"/>
<item name="car" value="alto"/>
<item name="currency" value="dollar"/>
</doc>
Document 2:
<doc>
<item name="vegetable" value="okra"/>
<item name="fruit" value="apple"/>
<item name="car" value="swift"/>
<item name="currency" value="dollar"/>
</doc>
Document 3:
<doc>
<item name="fruit" value="banana"/>
<item name="color" value="blue"/>
<item name="car" value="verna"/>
<item name="currency" value="rupee"/>
</doc>
Referring to the above example, two or more documents are said to be linked if
the item element with @name = currency and their @value matches. Thus, in the
above case, document 1 is linked to document 2 but not document 3.
In order to get the URIs of all the linked document, I think of using the
following approach:
Since attribute range indexes on both @name and @value are available, all the
matching @value for which @name = currency can be grouped together. Once all
the groups are obtained, I will return the URI of the documents from each
group. Using the URIs, I will add an element in each of the documents from a
group which will serve as a link between them.
However, I am not sure how I can form groups just by referring to range
indexes. Please help me construct the XQUERY to get the desired result.
Thanks and Regards,
Nachiketa
