问题描述
如何删除这些内容：
<td> </td>
或
<td width="7%"> </td>
？我尝试了很多方法，但是这些不间断的空格字符与普通的JSoup表达式或选择器不匹配。
from my JSoup 'Document'? I've tried many methods, but these non-breaking space characters do not match anything with normal JSoup expressions or Selectors.
推荐答案
HTML实体& nbsp; （ Unicode字符NO-BREAK SPACE U + 00A0 ）可以用字符 \ u00a0 表示。假设您要删除包含该字符的每个元素作为自己的文本（因此不是您在评论中所说的每个行），那么以下内容应该有效：
The HTML entity (Unicode character NO-BREAK SPACE U+00A0) can in Java be represented by the character \u00a0. Assuming that you want to remove every element which contains that character as own text (and thus not every line as you said in a comment), then the following ought to work:
document.select(":containsOwn(\u00a0)").remove();
如果你真的想删除整个行那么你最好的选择是真的要逐行扫描HTML。
If you really mean to remove the entire line then your best bet is really to scan HTML yourself line by line.
