Merging elements inside a xml.etree.ElementTree
- by theAlse
I have a huge test data like the one provided below (and yes I have no control over this data). Each line is actually 6 parts and I need to generate an XML based on this data.
Nav;Basic;Dest;Smoke;No;Yes;
Nav;Dest;Recent;Regg;No;Yes;
Nav;Dest;Favourites;Regg;No;Yes;
...
Nav;Dest using on board;By POI;Smoke;No;Yes;
Nav;Dest using on board;Other;Regg;No;Yes;
The first 3 elements on each line denotes "test suites"-XML element and the last 3 element should create a "test case"-XML element.
I have successfully converted it into a XML using the following code:
# testsuite (root)
testsuite = ET.Element('testsuite')
testsuite.set("name", "Tests")
def _create_testcase_tag(elem):
global testsuite
level1, level2, level3, elem4, elem5, elem6 = elem
# -- testsuite (level1)
testsuite_level1 = ET.SubElement(testsuite, "testsuite")
testsuite_level1.set("name", level1)
# -- testsuite (level2)
testsuite_level2 = ET.SubElement(testsuite_level1, "testsuite")
testsuite_level2.set("name", level2)
# -- testsuite (level3)
testsuite_level2 = ET.SubElement(testsuite_level2, "testsuite")
testsuite_level2.set("name", level3)
# -- testcase
testcase = ET.SubElement(testsuite_level2, "testcase")
testcase.set("name", "TBD")
summary = ET.SubElement(testcase, "summary")
summary.text = "Test Type= %s, Automated= %s, Available=%s" %(elem4, elem5, elem6)
with open(input_file) as in_file:
for line_number, a_line in enumerate(in_file):
try:
parameters = a_line.split(';')
if len(parameters) >= 6:
level1 = parameters[0].strip()
level2 = parameters[1].strip()
level3 = parameters[2].strip()
elem4 = parameters[3].strip()
elem5 = parameters[4].strip()
elem6 = parameters[5].strip()
lines_as_list.append((level1, level2, level3, elem4, elem5, elem6))
except ValueError:
pass
lines_as_list.sort()
for elem in lines_as_list:
_create_testcase_tag(elem)
output_xml = ET.ElementTree(testsuite)
ET.ElementTree.write(output_xml, output_file, xml_declaration=True, encoding="UTF-8")
The above code generates an XML like this:
<testsuite name="Tests">
<testsuite name="Nav">
<testsuite name="Basic navigation">
<testsuite name="Set destination">
<testcase name="TBD">
<summary>Test Type= Smoke test Automated= No, Available=Yes</summary>
</testcase>
</testsuite>
</testsuite>
</testsuite>
<testsuite name="Nav">
<testsuite name="Set destination">
<testsuite name="Recent">
<testcase name="TBD">
<summary>
Test Type= Reggression test Automated= No, Available=Yes
</summary>
</testcase>
</testsuite>
</testsuite>
</testsuite>
</testsuite>
...
This is all correct, but as you can see I have created a whole tree for each line and that is not what I need. I need to combine e.g. all testsuite with the same name into one testsuite and also perform that recursively.
So the XML looks like this instead:
<testsuite name="Tests">
<testsuite name="Nav">
<testsuite name="Basic navigation">
<testsuite name="Set destination">
<testcase name="TBD">
<summary>Test Type= Smoke test Automated= No, Available=Yes</summary>
</testcase>
</testsuite>
<testsuite name="Recent">
<testcase name="TBD">
<summary>
Test Type= Reggression test Automated= No, Available=Yes
</summary>
</testcase>
</testsuite>
</testsuite>
</testsuite>
</testsuite>
I hope you can understand what I mean, but level1, level2 and level3 should be unique with testcases inside.
How should I do this? Please do not suggest the use of any external libraries! I can not install new libraries in customer site. xml.etree.ElementTree is all I have.
Thanks
