Hi,
I have an xml in the below form:
<a>
<b>
<c href="input1"/>
<c href="input2"/>
<c href="input1"/>
<c href="input1"/>
<c href="input1"/>
<c href="input3"/>
<c href="input3"/>
<c href="input1"/>
<c href="input1"/>
<c href="input1"/>
</b>
<b>
<c href="input1"/>
<c href="input2"/>
<c href="input1"/>
<c href="input1"/>
<c href="input1"/>
</b>
</a>
I want to retain the <c> elements with unique @href. The duplicate entries
should be removed.
Thus, the output should be:
<a>
<b>
<c href="input1"/>
<c href="input2"/>
<c href="input3"/>
</b>
<b>
<c href="input1"/>
<c href="input2"/>
</b>
</a>
I have written the below xquery for the same:
declare namespace functx = "http://www.functx.com";;
declare function functx:is-node-in-sequence
( $var2ode as node()? ,
$seq as node()* ) as xs:boolean {
some $var2odeInSeq in $seq satisfies $var2odeInSeq is $var2ode
} ;
for $var1 in doc("/abc.xml")//b
let $count := fn:count($var1/c)
for $var2 in 1 to $count
where ($count > 1 and fn:not(($var2 + 1) >= $count))
return for $var3 in ($var2 + 1) to $count
where functx:is-node-in-sequence($m/citation[$var3], $m/citation)
return xdmp:node-delete($m/c [$var3])
But, I am getting xdmp:conflictingupdates exception.
Please suggest an alternative to get the desired output.
Regards,
Nachiketa Kulkarni
