I think part of the issue here is that holo isn't quite sure of
what information [s]he needs out of the XML reply and how to do
that with XPath. The first post mentioned getting instanceId and
launchTime, so I'll start there using the AWS example XML found
here:
https://github.com/polopoly/cloud-ui/blob/master/aws/examples/DescribeInstances.xml
You can find all parent nodes that provide this set of
information with XPath query "//instancesSet/item". From there,
you can iterate over the list and pull out the information you
need:
auto parents = root.parseXPath("//instancesSet/item");
foreach(parent; parents) {
string instanceId =
parent.parseXPath("instanceId")[0].getCData();
string launchTime =
parent.parseXPath("launchTime")[0].getCData();
}
In the process of checking this out, I discovered that subnode
predicates are broken (attribute predicates work just fine, I
need to write more unittests). I guess I have some things to work
on tonight.
