I am using Java and Jsoup library to parse the text out of html. In the html I have two options called Single and Multiple. Both have a check mark next to them and if the option selected is Single the checkbox is check and the box the Multiple is not checked. I need to find a way using code which option is selected whether it's multiple or single. I truly appreciate your help. Thank you.

推荐答案

尝试一下:

Document doc = Jsoup.parse(html);
String selected = doc.select("tr:contains(☒) td:eq(1)").first().text();

selected然后应包含所选选项"Single"或"Multiple"的文本.

selected should then contain the text of the selected option, "Single" or "Multiple".

tr:contains(☒)选择器选择包含☒符号的表行，然后td:eq(1)选择该行中的第二个表单元格. (它从0开始计数，所以第一个单元格是数字0，第二个单元格是数字1，依此类推.)

The tr:contains(☒) selector picks the table row that contains the ☒ symbol, and td:eq(1) then selects the second table cell in that row. (It counts starting at 0, so the first cell is number 0, the second cell is number 1 etc.)
