如何删除“&＃31; "来自java中字符串的字符？ [英] How to remove " " charecter from string in java?

问题描述

你好

我写这段代码删除？来自字符串。

但是当我在xml文件中写入时它存在吗？

.replaceAll不起作用？



我尝试过：

hello
i write this code for remove "" from string.
but when i write in xml file it exist?
the .replaceAll not work?

What I have tried:

org.jsoup.nodes.Document doc =  Jsoup.parse(rs.getString("flds"));
                org.jsoup.nodes.Document doc1 =  Jsoup.parse(rs.getString("sfld"));
                System.out.println(doc.getElementsByTag("img").attr("src"));
                String front=doc1.text();
                String back=doc.text().replaceAll("","");

推荐答案

可能没有正确地从您的代码字符串中翻译它。最好使用字符代码。



该字符的十六进制代码是％1F所以..

Maybe it isn't being translated from your code string properly. Best to use the char code.

The hex code for that char is "%1F" so..

int charInt = 0x1F;

然后

and then

char c = (char)charInt;

这可以直接插入到您的代码中

This can then be inserted directly into your code

org.jsoup.nodes.Document doc =  Jsoup.parse(rs.getString("flds"));
                org.jsoup.nodes.Document doc1 =  Jsoup.parse(rs.getString("sfld"));
                System.out.println(doc.getElementsByTag("img").attr("src"));
                String front=doc1.text();
                String back=doc.text().replaceAll(String.valueOf(c),"");

我无法测试这个，但我希望它有帮助

I have no means to test this, but I hope it helps
