<?xml version="1.0" encoding="iso-8859-15"?> <output>     <response>         <error>0</error>     <response> <entries> <entry>     <line>0</line>     <id></id>     <first>2014-03-08</first>     <last>0</last>     <md5>12e00ed477ad6</md5>     <virustotal></virustotal>     <vt_score></vt_score>     <scanner></scanner>     <virusname></virusname>     <url>eva247.com/image/</url>     <recent></recent>     <response></response>     <ip></ip>     <as></as>     <review></review>     <domain>eva247.com</domain>     <country></country>     <source></source>     <email></email>     <inetnum></inetnum>     <netname>tam nhin moi</netname>     <descr></descr>     <ns1></ns1>     <ns2></ns2>     <ns3></ns3>     <ns4></ns4>     <ns5></ns5> </entry> <entry>     <line>1</line>     <id></id>     <first>2014-02-06</first>     <last>0</last>     <md5>de7db4cbe86d34373eb70</md5>     <virustotal></virustotal>     <vt_score></vt_score>     <scanner></scanner>     <virusname>n/a</virusname>     <url>files.downloadsmart.net</url>     <recent></recent>     <response></response>     <ip></ip>     <as>7643</as>     <review></review>     <domain>files.do</domain>     <country></country>     <source></source>     <email></email>     <inetnum></inetnum>     <netname>(vnpt)</netname>     <descr></descr>     <ns1></ns1>     <ns2></ns2>     <ns3></ns3>     <ns4></ns4>     <ns5></ns5> </entry>

here code: 

fp = open("2014-03-12_16.19.xml","r")  tmp = fp.read()  line in tmp:      fileopen = open("danh_sach_xml_new.xml","a")      match = re.search(r"(\d{4}-\d{2}-\d{2})", line)      if match:          result = match.group(1)          newline = result.replace(result,_timestamp_(result))          fileopen.write(newline)      else:          fileopen.write(line)      fileopen.close()  fp.close()

and

def _timestamp_(date):      list_date = date.split("-")      pprint.pprint(list_date)      t = (int(list_date[0]), int(list_date[1]), int(list_date[2]),0,0,0)      time_stamp = time.mktime(t)      return time_stamp

there many xml parsers available in python, elementtree has an example in documentation shows how modify xml file.

here how use that:

>>> import time >>> import datetime >>> import xml.etree.elementtree et >>> tree = et.parse('test.xml') >>> root = tree.getroot() >>> entry in root.find('entries').findall('entry'): ...     entry.find('first').text = str(time.mktime( ...                                datetime.datetime.strptime(entry.find('first').text, ...                                                           "%y-%m-%d").timetuple())) ... >>> tree.write('new.xml')

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
