java - charset of the attribute values in Jsoup -

-

i use jsoup , need pick attribute values of tags inside html document in ascii-encoding maintaining them are, without converting them.

so, have following html document 

<!doctype html> <head>     <meta charset="ascii">         </head> <body>     <div title="2 &gt; 1, 1 > 0, &agrave; vs &egrave;">         3 &gt; 2,  1 > 0     </div> </body>

which want parse means of jsoup.

i need extract value of title attribite is: 2 &gt; 1, 1 > 0, &agrave; vs &egrave;.

i've create document object doc below (it in kotlin, don't think important here):

val charset = charset.forname("ascii") val doc = jsoup.parse(file("test.html").readtext(charset)) doc.outputsettings().charset(charset)

when print out doc means of 

println(doc.tostring())

i following string

<!doctype html> <html>  <head>    <meta charset="ascii">   </head>   <body>    <div title="2 > 1, 1 > 0, &agrave; vs &egrave;">     3 &gt; 2    </div>   </body> </html>

which differs file content title attribute value (&gt; gets transformed > in string "2 > 1"), while rest of document ok.

then, inspecting attribute value 

 doc.body().select("div").foreach { div -> println("title = ${div.attr("title")}") }

produces following string

title = 2 > 1, 1 > 0, à vs è

notice, &agrave; , &egrave; transformed à , è.

my question is: in jsoup, how can attribute values of html tags preserving way written in input file?

in example above need string "2 &gt; 1, 1 > 0, &agrave; vs &egrave;" (as written in input file) , not "2 > 1, 1 > 0, &agrave; vs &egrave;" niether "2 &gt; 1, 1 &gt; 0, à vs è".

the attr() method returns string without html entities , not find way keep html entities. however, can use jsoup.clean() method convert characters in string entities.

val charset = charset.forname("ascii") val doc = jsoup.parse(file("test.html").readtext(charset)) doc.body().select("div").foreach { div ->     val title = jsoup.clean("${div.attr("title")}", "", whitelist.none(), document.outputsettings().charset(charset))     println("title = $title") }

the result is:

title = 2 &gt; 1, &agrave; vs &egrave;

of course, might not solution use case.

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.

when draw attributed string fixed line height text kit, characters aligned bottom of line fragment. while make sense on 1 line characters varying in size, breaks flow of text multiple lines. baselines appear decided largest descender each line. i've found article people behind sketch explaining exact problem in bit more detail , showing solution does, not explaining how achieved this. this want basically: when showing 2 lines large line height, result far ideal: the code i'm using: let smallfont = uifont.systemfont(ofsize: 15) let bigfont = uifont.systemfont(ofsize: 25) let paragraphstyle = nsmutableparagraphstyle() paragraphstyle.minimumlineheight = 22 paragraphstyle.maximumlineheight = 22 var attributes = [ nsfontattributename: smallfont, nsparagraphstyleattributename: paragraphstyle ] let textstorage = nstextstorage() let textcontainer = nstextcontainer(size: cgsize(width: 250, height: 500)) let layoutmanager = nslayoutmanager() textstorage.append(n...
