Alternative to GetElementById

[Billy]

I wish to select a node using the value of one of its attributes, i.e.

xml:
....
<tablelist>
<table name="table1">
...
</table>
<table name="table2">
...
</table>
...
</tablelist>
....

Method Call: element = xmlDoc.GetElementById("table1")

But from what I have been reading and tested this only works if I am
using DTD and the attribute is of type ID. I don't want to use a DTD
(already using XSD) so how can I either use this method or is there an
alternative that doesn't tie me to using DTD's?
Note, I know I can select all of the nodes in the <tablelist> node and
then loop but I would rather not as this list could be huge.

Thanks

Billy

Depending on the DOM implementation/API you use it might for instance be
possible to use an XPath expression e.g.
/tablelist/table[@name = 'table1']
to look for that element.
But you haven't told us anything on what DOM implementation you use so I
can't tell whether XPath is possible for you or not.

It might also suffice if your XSD declares the name attribute of <table>
elements to be of type ID so that getElementById works.

Thanks Martin for a prompt reply,

It works a treat, i've seen that syntax before now you've shown me it
... I will hopefully now remember it.

Thanks very much for your time.

Note: I am implementing the DOM object using .net c# and xpath is
available.
