char[] pommidchar = { ';' }; webrequest request = webrequest.create( "http://localhost:49443/wyniki.html"); request.credentials = credentialcache.defaultcredentials; webresponse response = request.getresponse(); console.writeline(((httpwebresponse)response).statusdescription); stream datastream = response.getresponsestream(); streamreader reader = new streamreader(datastream); string responsefromserver = reader.readtoend(); // console.writeline(responsefromserver); htmlagilitypack.htmldocument doc = new htmlagilitypack.htmldocument(); doc.loadhtml(responsefromserver); // console.writeline(doc); string formatstring = "yyyymmddhhmm";//201510060000; reader.close();// = "201510060000" response.close(); string[] slowa; string tekst ; foreach (htmlnode node in doc.documentnode.selectnodes("//body")) { string temp = ""; console.writeline(node.innertext); id = node.innertext; tekst = node.innertext; //console.writeline("node"+node.tostring()); slowa = id.split(pommidchar); temp = slowa[1] + slowa[2]; //console.writeline(slowa[30]); console.writeline("string pobrany ze strony"+temp); datetime dt = datetime.parseexact(temp, formatstring, cultureinfo.invariantculture, datetimestyles.none); console.writeline("ostatnia dana z parse:" + dataparse1.tostring("yyyy-mm-dd hh:mm")); console.writeline("aktualna pobrana z urzadzenia:" + dt.tostring("yyyy-mm-dd hh:mm")); } in tekst have string //body want read line line , copmare date :
using (stringreader readerr = new stringreader(tekst)) { string[] splitline; string line; while ((line = readerr.readline()) != null) { console.writeline(line); splitline = line.split(pommidchar); // console.writeline(splitline[0]); console.writeline(splitline[1]); } readerr.close(); } but , here clue .i have 1 string in "splitstring" 001 . can describe me others string line? work slowa = id.split(pommidchar); work , split exacly want can`t read line line .
i pass question becuse done. have 1 more stupid question someone. dr university change soruce code web. variables (html code) set in 1 row licke
<body> <pre><br>001;20151006;000034;1800;1000;999;1<br>001;20151006;000035;1800;1000;999;1;<br>001;20151006;000036;1800;1000;999;1;</pre> </body>so , how can take string br tag . solution take them in 1 row . thinking loop lenght string . wrong becuse don`t know how string must get. remember 1 "quete" start "001" , end "1". try node
htmlnode node in doc.documentnode.selectnodes("//body/pre/br") but don`t work.
you need select p tags... i'd expect selectnodes("//p") or selectnodes("//body/p") instead of selecting single body element (which inner text contain concatenation of strings inside p tags).
