python - How to parse xml-file with directory structure -


i've got xml-file containing directory structure files want put tar.gz file (flattened).

how should parse xml extract path each file?

right i'm using lxml , finding paths this:

paths = [] case in root.iter('case'):     language in case.iter('language'):         result in language.iter('result'):             file in result.iter('file'):                 paths.append('/'.join([node.get('id') node in [case, language, result, file]]))

but feels bit hardcoded , not work if structure change.

i can find each file-node root.iter('file'), how can parents/directories each node/file? or should (completely?) different way?

the xml looks this:

<?xml version="1.0" encoding="utf-8"?> <files batch="regular">     <case id="case_10_some_description">         <language id="english">             <result id="images">                 <file id="screenshot_1.png"/>                 <file id="screenshot_2.png"/>                 <file id="screenshot_3.png"/>                 <file id="screenshot_4.png"/>                 <file id="screenshot_5.png"/>                 <file id="screenshot_6.png"/>             </result>         </language>     </case>     <case id="case_12_some_description">         <language id="english">             <result id="images">                 <file id="screenshot_1.png"/>                 <file id="screenshot_2.png"/>                 <file id="screenshot_3.png"/>             </result>         </language>     </case> </files>

and files:

regular/case_10_some_description/english/images/screenshot_1.png regular/case_10_some_description/english/images/screenshot_2.png regular/case_10_some_description/english/images/screenshot_3.png regular/case_10_some_description/english/images/screenshot_4.png regular/case_10_some_description/english/images/screenshot_5.png regular/case_10_some_description/english/images/screenshot_6.png regular/case_12_some_description/english/images/screenshot_1.png regular/case_12_some_description/english/images/screenshot_2.png regular/case_12_some_description/english/images/screenshot_3.png

do create file-schema on own? if can change it, definitly. try make this:

<?xml version="1.0" encoding="utf-8"?> <directory id="regular">     <directory id="case_10_some_description">         <directory id="english">             <directory id="images">                 <file id="screenshot_1.png"/>                 <file id="screenshot_2.png"/>                 <file id="screenshot_3.png"/>                 <file id="screenshot_4.png"/>                 <file id="screenshot_5.png"/>                 <file id="screenshot_6.png"/>             </directory>         </directory>     </directory>     <directory id="case_12_some_description">         <directory id="english">             <directory id="images">                 <file id="screenshot_1.png"/>                 <file id="screenshot_2.png"/>                 <file id="screenshot_3.png"/>             </directory>         </directory>     </directory> </directory>

always give tag same name if have same meaning. maybe use more different attributes tag, make parsing easier
