XPATH and concat

[ranadhir nag]

We have an xml viz.
<element>
<component>....</component>
<event>....</event>
<event>....</event>
<event>....</event>
<event>....</event>
</element>

The number of events will be dynamic.
For a relevant component,we need to return the cooresponding events pipe-delimited.
We arrive at the particular component through SelectNodes - is there a smart,concise XPATH expression which can allow me to return the set of events in the way we want,rather than recursing through the set.
Note that component and event nodes are parent(ed) by 'element'.
We are using javascript.

Look at the string-join() xpath method.
