When im checking instance name with such code:
auto test =
list.parseXPath(`//tagSet/item[key="Name"]/value`)[0].goCData;
it is compiling properly but it is breaking program when is no
name set.
I make quick workaround:
You can write a helper:
XmlNode selectSingleNode(XmlNode src, string path)
{
XmlNode[] nodes = src.parseXPath(path);
return nodes.length==0 ? null : nodes[0];
}
Then:
string test1 = node.selectSingleNode(`//instanceId`).getCData();

Select parent tags and get data from their child tags like
instanceId.

That's an XPath expression.
Need, to read about that XPaths.
How to drop tags from respond? I have such result of parsing
by id
Sorry i was trying to use that XPaths to take out instanceId and
laounchTime but i always get an empty respond.
//instanceId/launchTime" - empty
//instanceId/* - empty too
//instanceId.launchTime - empty too
How to take instance id and variable which im interest in or

If you don't want parent tag, then:
XmlNode[] searchlist2 = newdoc.parseXPath("//launchTime");

I wanted parent tag, i think. I almost figure out what i needed,
but getCData stops working :/

string xmlstring =
I have no idea what i'm doing, but i did it (i just choose 1
element of array):
void main()

string xmlstring = cast(string)read("test.xml");
XmlNode newdoc = xmlstring.readDocument();
XmlNode[] searchlist =
newdoc.parseXPath(`//instancesSet/item`);
foreach(list;
12 matches
