Junit 4test result parsing not able to find <failure> tag - junit4

Question

here is my Junit test result.xml
I am able to get hold of testsuite and testcase nodes. Now I need to check if test case is failed.
I am using an approach where I check if testcase node has any child and then check if that child is failure node. But when I try to get hold of child node and its type, it returns only the TEXT_NODE and displays failure message text. How do I check if child node is failure?
<?xml version='1.0' encoding='UTF-8' ?>
<testsuite name="com.Test" tests="47" failures="1" errors="0" skipped="0" time="0.425" timestamp="2017-05-25T10:04:14" hostname="localhost">
<properties>
<property name="device" value="Nexus_6_API_22(AVD) - 5.1.1" />
<property name="flavor" value="DEV" />
<property name="project" value="test" />
</properties>
<testcase name="test_1" classname="com.Test" time="0.053" />
<testcase name="test_2" classname="com.Test" time="0.081" />
<testcase name="test_3" classname="com.Test" time="0.0" />
<testcase name="test_4" classname="com.Test" time="0.001">
<failure>junit.framework.ComparisonFailure: expected:<512[]> but was:<512[fed_]>
at junit.framework.Assert.assertEquals(Assert.java:85)
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1853)
</failure>
</testcase>
</testsuite>

Answer 1

Well, I figured this out as below, posting for the benefit of others -
//Get a list of test cases with below code -
testCaseList = docElement.getElementsByTagName(TEST_CASE_TAG);
//Iterate through the list and set each item to testElement
// Get Test Case status
TestStatus testCaseStatus = TestStatus.FAILED;
if(testElement.hasChildNodes()) {
//Check if test failed ?
elems = getDirectChildsByTagName(testElement, TEST_FAILURE_TAG);
if(elems != null && elems.size()>0) {
logger.info("failed Tests :"+elems.size());
testCaseStatus = TtuTestStatus.FAILED;
}
//Check if test skipped ?
else {
elems = getDirectChildsByTagName(testElement, TEST_SKIPPED_TAG);
if(elems != null && elems.size()>0) {
logger.info("Skipped Tests :"+elems.size());
testCaseStatus = TtuTestStatus.SKIPPED;
}
}
}
else {
testCaseStatus = TtuTestStatus.PASSED;
}
