Example

Considering the following two examples (examples/report_1.xml and examples/report_2.xml, respectively):

<?xml version="1.0" encoding="UTF-8"?>
<results version="2">
  <cppcheck version="1.82"/>
    <errors>
      Checking main.c ...
      <error id="uninitvar" severity="error" msg="Uninitialized variable: p" verbose="Uninitialized variable: p" cwe="908">
        <location file="main.c" line="4"/>
      </error>
    </errors>
</results>

<?xml version="1.0" encoding="UTF-8"?>
<results version="2">
  <cppcheck version="1.82"/>
    <errors>
      Checking main.c ...
      <error id="uninitvar" severity="error" msg="Uninitialized variable: p" verbose="Uninitialized variable: p" cwe="908">
        <location file="main.c" line="4"/>
      </error>
      <error id="uninitvar" severity="error" msg="Uninitialized variable: p" verbose="Uninitialized variable: p2" cwe="908">
        <location file="main.c" line="5"/>
      </error>
    </errors>
</results>

The script produces the following two outputs (without options and using option -r, respectively):

$ python merge_cppcheck_reports.py examples/report_1.xml examples/report_2.xml
<results version="2">
  <cppcheck version="1.82" />
    <errors>
      Checking main.c ...
      <error cwe="908" id="uninitvar" msg="Uninitialized variable: p" severity="error" verbose="Uninitialized variable: p">

      </error>
      <error cwe="908" id="uninitvar" msg="Uninitialized variable: p" severity="error" verbose="Uninitialized variable: p">

      </error>
      <error cwe="908" id="uninitvar" msg="Uninitialized variable: p" severity="error" verbose="Uninitialized variable: p2">
        <location file="main.c" line="5" />
      </error>
    </errors>
</results>
