Subject: RE: [wsbpel] Groups - New Action Item #0067 Change example XPath expression ...
The example Xpath expressions from those two lines are as follows: . a single XML infoset item: e.g. $myFooVar/lines/line[2] . a collection of XML infoset items e.g. $myFooVar/lines After reading that, I imagine that the XML might look like this: <var> <lines> <line>one</line> <line>two</line> <line>three</line> </lines> </var> The first expression illustrates selecting a single infoset item, which would result in the 2nd line element. The second expression would select a single element, the lines element. This element has multiple children, but it's still a single element. In order to get multiple elements back from the expression you would have to select the individual lines. This could be done a number of ways but I think $myFooVar/lines/* is the clearest. If I misread the above or if you feel strongly about keeping the current example then I'll remove the action item since it's a minor thing and I don't want to open debate on a section we already reviewed.

Hi Mark, I am not sure I follow your suggestion/comment. My expectation/interpretation is: "lines" is the parent element of multiple "line" elements.

The new example better illustrates that we're expecting to get multiple "line" elements (and other children) while the previous example would only return a collection if there were multiple "lines" elements. > >View Details: >http://www.oasis-open.org/apps/org/workgroup/wsbpel/members/action_item.php ?action_item_id=1426 > > > >PLEASE NOTE: If the above links do not work for you, your email application >may be breaking the link into two pieces.
