java - get all attributes in html string in jsoup -



java - get all attributes in html string in jsoup -

i have string in html format , trying attributes , values using jsoup.

string is

string string= "<button class=submit btn primary-btn flex-table-btn js-submit type=submit>sign in</button>"; document doc = jsoup.parse(string); seek { org.jsoup.nodes.attributes attrs = doc.attributes(); for( org.jsoup.nodes.element element : doc.getallelements() ) { for( attribute attribute : element.attributes() ) { system.out.println( attribute.getkey() + " --::-- "+attribute.getvalue() ); } } } grab (exception e) { e.printstacktrace(); }

my desired output ::

key: **class** , value is: **submit btn primary-btn flex-table-btn js-submit** key: **type** , value is: **submit**

but this

key: class , value is: submit key: btn , value is: key: primary-btn , value is: key: flex-table-btn , value is: key: js-submit , value is: key: type , value is: submit

this because of quotes. if utilize

string string= "<button class='submit btn primary-btn flex-table-btn js-submit' type='submit'> sign in</button>";

i desired output.but trying without quotes.

you can't without quotes, because quotes not optional. without quotes, html you've quoted describes element one class (submit) , series of non-class, invalid additional attributes names btn, flex-table, etc., , that's how browser interpret it, jsoup doing. if meant additional classes on element, quotes required.

from the specification:

unquoted attribute value syntax

the attribute name, followed 0 or more space characters, followed single u+003d equals sign character, followed 0 or more space characters, followed attribute value, which, in add-on requirements given above attribute values, must not contain literal space characters, u+0022 quotation mark characters ("), u+0027 apostrophe characters ('), "=" (u+003d) characters, "<" (u+003c) characters, ">" (u+003e) characters, or u+0060 grave accent characters (`), , must not empty string.

note "must not contain literal space characters" part i've emphasized.
