Question

I have a XML where I have several <testcase> tags. Some of them have attribute "ident" with value "pr", some not.

<testcase>
  <teststep ident="Preparation" result="na">blabla</teststep>
  <teststep ident="" result="pass">blabla</teststep>
  <teststep ident="-" result="na">blabla</teststep>
  <teststep ident="Info" result="na">blabla</teststep>
  <teststep ident="1" result="pass">blabla</teststep>
  <teststep ident="2" result="pass">blabla</teststep>
  <teststep ident="3" result="pass">blabla</teststep>
  <teststep ident="4" result="fail">blabla</teststep>
  <teststep ident="PR" result="na">blabla</teststep>
  <verdict result="fail" />
</testcase>

I would like to query testcases which contains ident attribute with value "pr"

IEnumerable<XElement> failedPRTCs = report.Descendants("testcase").Where(t => t.Element("verdict").Attribute("result").Value == "fail" && t.Descendants("teststep").Where(ts=> ts.Attribute("ident").Value == "pr").ToList().Count > 0).ToList();

Current query returns 0. Whats the problem?

Was it helpful?

Solution

Looks like a simple problem of casing! "pr" vs "PR"! I would also recommend using Any rather than count > 0:

IEnumerable<XElement> failedPRTCs = report.Descendants("testcase")
    .Where(t => t.Element("verdict").Attribute("result").Value == "fail" &&
           t.Descendants("teststep").Any(ts=> ts.Attribute("ident").Value == "PR"));
