我需要在HTML源代码中找到一个单词.我还需要计算发生的次数.我正在尝试使用正则表达式.但它说找到0个匹配项.

I need to find a word in a HTML source code. Also I need to count occurrence. I am trying to use regular expression. But it says 0 match found.

我正在使用正则表达式，因为我认为这是最好的方法.如果有更好的方法，请告诉我.

I am using regular expression as I thought its the best way. In case of any better way, please let me know.

我需要在HTML源代码中查找单词"hsw.ads"的出现.

I need to find the occurrence of the word "hsw.ads" in HTML source code.

我已采取以下步骤.

int count = 0;
{
    Pattern p = Pattern.compile(".*(hsw.ads).*");
    Matcher m = p.matcher(SourceCode);
    while(m.find())count++;
}

但计数为0；

请让我知道您的解决方案.

Please let me know your solutions.

推荐答案

您应该尝试一下.

private int getWordCount(String word,String source){
        int count = 0;
        {
            Pattern p = Pattern.compile(word);
            Matcher m = p.matcher(source);
            while(m.find()) count++;
        }
        return count;
    }

在字符串中传递要搜索的单词(非模式).

Pass the word (Not pattern) you want to search in a string.
