xml - Error getting Python script to run on older version -


i had tested web based application uses python (2.7.8) scripts create dynamic content.

i parsing xml data , performing several operations on it.

one of operations requires searching type of data uses findall(xpath) function elementtree.

now place need deploy linux box has older version of python (2.6.6).

i had trouble due older elementtree not having capabilities.

i followed elementtree syntaxerror: expected path separator ([). copied elementtree 2.7.8 new box , imported there.

it imports fine different error follows:

traceback (most recent call last):   file "./filename_python.py", line 117, in <module>     ch in child.findall(xpath):   file "/usr/lib64/python2.6/xml/etree/elementpath.py", line 293, in findall     return list(iterfind(elem, path, namespaces))   file "/usr/lib64/python2.6/xml/etree/elementpath.py", line 194, in select     if "".join(e.itertext()) == value: attributeerror: itertext

i cannot update python version on box , cannot add modules new has imported locally.

any appreciated.

thank you.

it doesn't seem me you've backported 2.7.x version library properly. take @ stack trace , see still referring library in python 2.6.x path:

/usr/lib64/python2.6/xml/etree/elementpath.py

you consider lxml - don't need install system library. clone git repository here, , copy code projects directory.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
