Convert Umlaut in existing HTML String (Java function) -


i need java function convert umlaute in existing html-string. example have

<html> <body> äü </body>  </html>

now function should convert types of umaute escaped form. should leave html code intact replace -> ä , ü -> ü in above example resulting in

<html> <body> &auml;&uuml; </body> </html>

i aware of fact there loads of escaping functions in escapehtml4 . problem html converted html code escaped. looking function identifies text-parts within html code , encodes them.

furthermore setting utf-8 encoding not option me in case.

you have parse html file first, , apply escaping on relevant parts.

for example, jsoup html parser. can iterate on html elements, , manipulate content.

update: turns out simple jsoup:

import org.jsoup.jsoup; import org.jsoup.nodes.document;  public class stackoverflow {      static final string html = "<html><body>äü</body></html>";      public static void main(string... args) {         document doc = jsoup.parse(html);         doc.outputsettings().escapemode(entities.escapemode.base);         doc.outputsettings().charset("ascii");         system.out.println(doc.tostring());     } }

produces:

<html>  <head></head>  <body>   &auml;&uuml;  </body> </html>

by setting charset ascii in output settings, telling jsoup should output no utf-8 characters. result, jsoup escapes them.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
