Jmeter - beanshell中的正则表达式（matcher（）/ pattern（））正在削减国家字符 [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.

使用正则表达式提取器我得到

Use Regular Expression Extractor I get

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

我需要的是：Działalnośćleccnicza

from that i need just: "Działalność lecznicza"

所以我在Beanshell写一个程序应该这样做而且有问题因为我得到了

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 - 是我提取模式字的来源。
长度 - 告诉我我正在提取的单词数量。

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

程序对于没有国家字符的短语工作正常。这就是为什么我认为编码或某处有问题：

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}+(?=\\<)";

虽然对于这种类型的工作，我建议使用XML解析器，因为正则表达式完全不适合解析HTML / XML，如中所述这篇文章

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
