How to remove hard spaces with Jsoup?
提问by Carlos Goce
I'm trying to remove hard spaces (from entities in the HTML). I can't remove it with .trim()or .replace(" ", ""), etc! I don't get it.
我正在尝试删除硬空格（从 HTML 中的实体）。我不能用.trim()or.replace(" ", "")等删除它！我不明白。
I even found on Stackoverflow to try with \\u00a0but didn't work neither.
我什至在 Stackoverflow 上找到了尝试，\\u00a0但也没有奏效。
I tried this (since text()returns actual hard space characters, U+00A0):
我试过这个（因为text()返回实际的硬空间字符，U+00A0）：
System.out.println( "'"+fields.get(6).text().replace("\u00a0", "")+"'" ); //'94,00 '
System.out.println( "'"+fields.get(6).text().replace(" ", "")+"'" ); //'94,00 '
System.out.println( "'"+fields.get(6).text().trim()+"'"); //'94,00 '
System.out.println( "'"+fields.get(6).html().replace(" ", "")+"'"); //'94,00' works
But I can't figure out why I can't remove the white space with .text().
但我不明白为什么我不能用.text().

Your first attempt was very nearlyit, you're quite right that Jsoup maps to U+00A0. You just don't want the double backslash in your string:
您的第一次尝试非常接近，Jsoup 映射 到 U+00A0是完全正确的。您只是不希望字符串中出现双反斜杠：
System.out.println( "'"+fields.get(6).text().replace("\u00a0", "")+"'" ); //'94,00'
// Just one ------------------------------------------^
replacedoesn't use regular expressions, so you aren't trying to pass a literal backslash through to the regex level. You just want to specify character U+00A0 in the string.
replace不使用正则表达式，因此您不会尝试将文字反斜杠传递到正则表达式级别。您只想在字符串中指定字符 U+00A0。

New answer;
The hardspace, ie. entity (Unicode character NO-BREAK SPACE U+00A0 ) can in Java be represented by the character \u00a0,thus code becomes, where stris the string gotten from the text()method
新答案；硬空间，即。实体（Unicode 字符 NO-BREAK SPACE U+00A0 ）在 Java 中可以用这样的字符表示，\u00a0,代码变成，str从text()方法中得到的字符串在哪里
str.replaceAll ("\u00a0", "");
Old answer; Using the JSoup library,
旧答案；使用 JSoup 库，
import org.jsoup.parser.Parser;
String str1 = Parser.unescapeEntities("last week, Ovokerie Ogbeta", false);
String str2 = Parser.unescapeEntities("Entered » Here", false);
System.out.println(str1 + " " + str2);
Prints out:
打印出来：
last week, Ovokerie Ogbeta Entered ? Here
