Is it possible to use a distinct like statement?

[Fursten]

Hi,

Anyone knows if its possible to do suchthing like choose a collection of elements from a XML tree, and depending of the value of an attribute of those elements, get only one element per attribute.

For exemple, if I have this:

<table id=2>
</table>
<table id=3>
</table>
<table id=2>
</table>

I would like to get a colleccion of table elements like this:

<table id=2>
</table>
<table id=3>
</table>

So, I don´t need another table element because the ID is the same. In other words, I would like to make a distinct in my XPath... to obtain an element table per ID.

Something like: getElementsByTagName(&quot;//table/distinct ID&quot

Is this possible?

Thank you,

Sergio Oliveira

Hello,
Try selectNodes method. It will return a collection of nodes, and you could use RemoveChild method do remove unnecessary node.
Or keep track of your id-s in a loop and use method selectSingleNode which will return first match.
Then you have to construct collection of nodes by yourself.

Hope this helps.

You must be able to use XSL:Key somehow. If I get chance over the weekend, I'll have a look.

Good luck.
