Java 如何通过考虑上一个单词和下一个单词来精确匹配字符串
我不熟悉Java 如何通过考虑上一个单词和下一个单词来精确匹配字符串,java,regex,xml,string,Java,Regex,Xml,String,我不熟悉javaregex。因此，我有一个xml文件，其中包含不同的节点。文件是- <Node id="855"/>PROFILE<Node id="862"/>:<Node id="863"/> <Node id="864"/>8<Node id="865"/> <Node id="866"/>years<Node id="871"/> <Node id="872"/>IT<Node id="

private void parseXml（ArrayList元素、字符串文件路径）{
布尔标志=假；
字符串nextId=“0”；
字符串xmlData=getTextWithNodesDataFromXml（文件路径）；
用于（字符串s:元素）{
系统输出打印项次；
字符串标记；
int-id；
字符串regex=“”；
如果（标志==false）{
regex=“（“+s+”）；
flag=true；
Pattern pattern1=Pattern.compile（regex）；
Matcher matcher1=pattern1.Matcher（xmlData）；
if（matcher1.find（））{
System.out.println（“找到匹配-->”+s）；
}
}
因此，第一个参数是一个数组列表，其中包含要匹配的字符串的标记，第二个参数是文件的路径。
xmlDataPROFILEString.split（\\s+”）在这种情况下，您必须计算相似性的百分比

我逃避阅读文件而作弊

我被标题中的“考虑上一个和下一个单词”弄糊涂了。还使用了“profile”一词。你能添加几个不同的输入并说出你期望的输出吗？如果匹配，你是返回真/假，还是在节点文件中找到句子（元素）所在的位置开始？是的，我想找到句子开始和结束的节点的id。基本上，我想要开始和结束偏移量。@hack_on我的意思是文件可以多次包含配置文件字。但是在配置文件字之后，剩余的字符串应该是相同的。所以，如果我们在第一个配置文件之后找到了三次配置文件，那么下一个不是：哪个是s所以，我想精确匹配整个字符串。我已经更新了答案，以便在一个文件中处理多个配置文件，并提取开始和结束ID。
