Jmeter - beanshell 中的正则表达式(matcher()/pattern())正在切割国家字符 [英] Jmeter - regex in beanshell (matcher()/pattern() ) is cutting national characters

问题描述

我需要从服务器响应数据中删除一些单词.

i need to cut some words from server response data.

使用我得到的正则表达式提取器

Use Regular Expression Extractor I get

<span class="snippet_word">Działalność</span> <span class="snippet_word">lecznicza</span>.</a>

我只需要:Działalność lecznicza"

from that i need just: "Działalność lecznicza"

所以我在 Beanshell 中编写了一个程序，它应该可以做到这一点，因为我得到了一个问题

so i write a program in Beanshell which should do that and there's a problem because i get

"lecznicza lecznicza"

"lecznicza lecznicza"

这是我的程序:

import java.util.regex;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

String pattern = "\w+(?=\<)";
String co = vars.get("tresc");
int len  = Integer.parseInt(vars.get("length"));
String phrase="";
StringBuffer sb = new StringBuffer();

Pattern r = Pattern.compile(pattern);
Matcher m = r.matcher(co);

for(i=0; i < len ;i++){
if (m.find()){
strbuf = new StringBuffer(m.group(0));
} 
else {
phrase="notfound";
}

sb.append(" ");
sb.append(strbuf);
}

phrase = sb.toString();

return phrase;

tresc - 是我提取模式词的来源.长度 - 告诉我我提取了多少个单词.

tresc - is my source from I extract pattern word. Length - tells me how many words i'm extracting.

对于没有国家字符的短语，程序运行良好.这就是为什么我认为编码或此处某处存在一些问题:

Program is working fine for phrase without national characters. Thats why I think there is some problem with encoding or somewhere here:

Pattern r = Pattern.compile(pattern);
Matcher m = r.matcher(co);

但我不知道如何更改我的代码.

but i don't know how to change my code.

推荐答案

w 与 unicode 不匹配.要匹配正则表达式中的 unicode，您可以使用 p{L}:

w does not match unicode. To match unicode in regex, you can use p{L}:

String pattern = "\p{L}+(?=\<)";

尽管对于此类工作，我建议使用 XML 解析器，因为正则表达式完全不适合解析 这篇文章

Although for this type of work I would recommend using an XML parser as regular expressions are completely unsuitable for parsing HTML/XML as described in this post
