im trying use xml configuration file java application getting exception on parsing. xml is: checked several people , told xml correct, did w3cvalidator. 

<?xml version="1.0" encoding="utf8"?> <config>     <devpath>"c:/users/fer/desktop/files/"</devpath>     <pfxname>keystore.pfx</pfxname>     <fontname>font.ttf</fontname>     <pfxpass>keystore_pass</pfxpass>     <keypass>key_pass</keypass> </config>

my code read , parse: 

private static void readxmlconfig() {     string devpath = null;     string pfxname = null;     string fontname;     string pfxpass;     string keypass;      document dom;     documentbuilderfactory dbf = documentbuilderfactory.newinstance();     try {         file file = new file("config");          documentbuilder db = dbf.newdocumentbuilder();         dom = db.parse(file);          element root = dom.getdocumentelement();         devpath = gettextvalue(devpath, root, "developer_route");         pfxname = gettextvalue(pfxname, root, "pfx_route");     } catch (exception e) {         e.printstacktrace();     } }  private static string gettextvalue(string def, element doc, string tag) {     string value = def;     nodelist nl;     nl = doc.getelementsbytagname(tag);     if (nl.getlength() > 0 && nl.item(0).haschildnodes()) {         value = nl.item(0).getfirstchild().getnodevalue();     }     return value; }

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
