xpath string concatenation function

[edA-qa]

The string() function in xpath just considers the first node (and its children) in a node-set. There are many cases where a concatenated result is desired instead.

For example, say you wish to get all the nodes following a particular <br/> node. You can easily specify the nodes you want like:

//br/following-sibling::node()

but string() will just take the first once. What we want is a concat function which takes the string() conversion of all of the nodes. Since the TypeConvert class can already do string() conversion the implementation of such a concat should be trivial.

set %Result% as concat //br/following-sibling::node()

Thinking about it the function need not even be related to Xpath, it could simply concatenate any iterable list relying on string conversion for those items.
