如何删除& nbsp;和Jsoup？ [英] How to remove   with Jsoup?
问题描述
我无法使用 .trim（）或 .replace（，）删除它等等！我不明白。
I can't remove it with .trim() or .replace(" ", ""), etc! I don't get it.
我甚至在Stackoverflow上发现尝试 \\\\ 0000 但是没有我也没办法。
I even found on Stackoverflow to try with \\u00a0 but didn't work neither.
我试过这个：
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
但我无法弄清楚为什么我无法删除 .text（）的空白区域。
But I can't figure out why I can't remove the white space with .text().
推荐答案
你的第一次尝试非常它，Jsoup映射<$你是对的c $ c>& nbsp; 到U + 00A0。您只是不希望字符串中出现双反斜杠：
Your first attempt was very nearly it, you're quite right that Jsoup maps to U+00A0. You just don't want the double backslash in your string:
System.out.println( "'"+fields.get(6).text().replace("\u00a0", "")+"'" ); //'94,00'
// Just one ------------------------------------------^
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。你只想在字符串中指定字符U + 00A0。
replace doesn'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.
