Items in a node list can be referenced using the [#] predicate (where # is the one-based node index). So to limit the application of the above overlay to only the first matching element you could use: | |||
<overlayitem match="//menupopup[@id='help-popup']'''[1]'''"> | |||
<menuitem id="help-xul" label="Help on XUL" /> | |||
</overlayitem> | |||
insertbefore/insertafter may not be needed because XPath has: | |||
preceding-sibling::*[1] | |||
following-sibling::*[1] | |||
