python encoding ' (quotation) in xml file -


i have xml file encoding information not specified. trying read , write file in location using below method

import xml.etree.elementtree et import pandas pd lxml import etree,html lxml.html.clean import cleaner,clean_html xml.sax.saxutils import escape, unescape, quoteattr open('check1.xml', 'rb') file:         xml_file = file.read() tree = html.fromstring(xml_file) tree1 = etree.elementtree(tree) tree1.write('path xml file', pretty_print=true, xml_declaration=true,encoding = 'utf-8')

input:

<unit>  <source>site name:  investigation's address</source>     <target></target> </unit>

output:

<unit>&#13;  <source>site name: investigationâsaddress </source>&#13;     <target/>&#13; </unit>&#13;

why these characters showing , why ' not displayed properly.i tried latin-1 encoding facing similar issue except ' different characters displayed.

don't use open() read xml files. wrong thing do.

xml parsers have own file handling. elementtree not exception. use et.parse() read files , et.write()—or tree.write()—to write them.

import xml.etree.elementtree et  tree = et.parse('check1.xml') tree.write('path xml file', pretty_print=true, xml_declaration=true, encoding='utf-8')

this simple parse-write cycle fix messed-up line endings, since \r\n is not proper line ending in xml; converted \n automatically.

background

in virtually cases, file handling functions in xml parsers deal file encodings. opening files , reading them strings breaks automatic handling, i.e. doing manually bug waiting happen.

if xml file missing xml declaration (<?xml version="1.0" encoding="..." ?>) assumed utf-8. if such file isn't utf-8 reason, it's, strictly speaking, broken.

xml-aware tools not create such files. if have such files, checking how created , fixing process should first priority.

if that's not option, trying fix such broken file only situation reading file string , giving string xml parser right solution. however, requires prior knowledge of file encoding, thing don't need bother when using et.parse().

assuming file in windows code page 1252, erroneously misses xml declaration, , want fix writing encoded version:

import xml.etree.elementtree et  open('check1.xml', encoding="cp1252") f:     tree = et.fromstring(f.read())  tree.write('path xml file', pretty_print=true, xml_declaration=true, encoding='utf-8')

unless in specific situation, use et.parse() read xml files.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
