python - How to remove specific item and lines from xml? -


i trying remove specific items , line xml.

-items remove: matched <error>...</error>

-lines remove: <errors> , </errors>

this xml file has fixed format system. cannot modify xml file. , added following line first , last line because have error during et.parse.

modified.write("<errors>\n" + data + "\n</errors>\n")

here whole script:

import xml.etree.elementtree et  include_pattern = 'include_pattern' output = 'test.xml' def remove_excluded_path_from_xml(_patterns, _file) :     #modify xml     open(_file, 'r') original:         data = original.read()     if len(data) == 0 :         return false     if data[0] != '<errors>':         open(_file, 'w') modified:             modified.write("<errors>\n" + data + "\n</errors>\n")  xml = et.parse(_file) root = xml.getroot()  errors = root.findall('error') error in root.iter('error'):     bmatch = false     item in error.iter():         file = item.findtext('file')         if file != none:             p in _patterns:                 if p in file:                     bmatch = true                     break     if bmatch == false:         root.remove(error) errors = root.findall('error') xml.write(_file) return true  if __name__ == '__main__':     print '[start] removing defects excluded paths'     #path include     open(include_pattern) f:         patterns = f.read().splitlines()     result = remove_excluded_path_from_xml(patterns, 'test.xml')     print '[end] removing defects excluded paths'

question

  1. i want know how remove 2 lines <errors> , </errors> inserted.

  2. there 2 lines different format after running script. want know how fix these differences.

could give me kind advice questions?

1) <path_event></path_event> changed <path_event /> 2) <description>{covlstrv2{{t{calling {0} without checking return value. library function may fail , return error code.}{{code{remove(&quot;/tmp/cached-concurrent2.db&quot;)}}}}}}</description> changed <description>{covlstrv2{{t{calling {0} without checking return value. library function may fail , return error code.}{{code{remove("/tmp/cached-concurrent2.db")}}}}}}</description>

additionally, attaching test.xml , include_pattern

test.xml

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
