括号内关键字后的正则表达式匹配字符串

Question

我需要在双引号之间匹配关键字后的值例如：

zoom_sensitivity "2"
sensitivity "99"
m_rawinput "0"
m_righthand "0"

也有不同的间距：

sensitivity"99"m_rawinput"0"zoom_sensitivity"2"m_righthand"0"

另一个例子：

sensitivity"99" m_rawinput "0"
m_righthand "0"
zoom_sensitivity"2"

我想在敏感度关键字或选择一个

后的两种情况下获得99值

我尝试的是： [\n\r]*["|\n\r\s]sensitivity\s*"([^\n\r\s]*)"

但如果关键字位于第一行或任何 whitespace/double 引号之前，则它不匹配，并且对于内联代码，它不仅匹配 99 值。我相信 Source Engine 从他们的 .cfg 文件中类似地解析它，也许有更好的方法。

Answer 1

您可以使用此正则表达式并从 group1 中捕获您的数字，

\bsensitivity\s*"(\d+)"

因为你想select 99 只在sensitivity之后作为一个完整的单词，需要在单词周围使用单词边界\b，比如\bsensitivity\b 和 \s* 允许匹配单词之间的可选空格，然后 " 匹配双引号，然后 (\d+) 匹配一个或多个数字并在 group1 中捕获，最后 " 匹配结束双引号。

Answer 2

你可以简单地使用这个：

(\w+)\s?"(\d+)"

输出

zoom_sensitivity "2"    zoom_sensitivity    2
sensitivity "99"        sensitivity         99
m_rawinput "0"          m_rawinput          0
m_righthand "0"         m_righthand         0
sensitivity"99"         sensitivity         99
m_rawinput"0"           m_rawinput          0
zoom_sensitivity"2"     zoom_sensitivity    2
m_righthand"0"          m_righthand         0
sensitivity"99"         sensitivity         99
m_rawinput "0"          m_rawinput          0
m_righthand "0"         m_righthand         0
zoom_sensitivity"2"     zoom_sensitivity    2

为此：

zoom_sensitivity "2"
sensitivity "99"
m_rawinput "0"
m_righthand "0"
also with different spacing:

sensitivity"99"m_rawinput"0"zoom_sensitivity"2"m_righthand"0"
another example:

sensitivity"99" m_rawinput "0"
m_righthand "0"
zoom_sensitivity"2"

您可以将其放入一个对象中，稍后再查询该对象：

var parse = function(content) {
  var myregexp = /(\w+)\s*"(\d+)"/mg;
  var match = myregexp.exec(content);
  while (match != null) {
    // matched text: match[0]
    // match start: match.index
    // capturing group n: match[n]
    console.log(match[1] + " => " + match[2]);
    // re-run the regex for the next item
    match = myregexp.exec(content);
  }
}

parse(document.getElementById("example1").innerHTML);
console.log("-----------");
parse(document.getElementById("example2").innerHTML);
console.log("-----------");
parse(document.getElementById("example3").innerHTML);

<div id="example1">
zoom_sensitivity "2"
sensitivity "99"
m_rawinput "0"
m_righthand "0"
</div>

<div id="example2">
sensitivity"99"m_rawinput"0"zoom_sensitivity"2"m_righthand"0"
</div>

<div id="example3">
sensitivity"99" m_rawinput "0"
m_righthand "0"
zoom_sensitivity"2"
</div>
