匹配引号内的换行符
[英]Match newline characters inside quotes
问题描述
I'm looking for a solution to replace the newline characters found inside an XML's attributes (XML string) in Javascript. 
我正在寻找一种解决方案来替换Javascript中XML属性（XML字符串）中的换行符。 (Trying to replace with so I do not lose newlines when parsing XML back) （尝试用 替换，因此在解析XML时我不会丢失换行符）
Note: There are other newlines in the string, eg after <main> .. </body> 注意：字符串中还有其他换行符，例如<main> .. </body>
(Open to any other regex/non-regex solutions!) （开放给任何其他正则表达式/非正则表达式解决方案！）
<main>
<head/><body><note text="Load">
<note text="2 Newlines at the end of this
newline"/>
</body>
</main>
All I have is this awful thing "[\\s\\S]*?([\\r\\n]+)[\\s\\S]*?" 我只剩下这可怕的东西"[\\s\\S]*?([\\r\\n]+)[\\s\\S]*?"

Here is a little snippet making the conversion: 以下是进行转换的小片段：
function convert(xmlStr) { var xml = document.createElement('xml'); xml.innerHTML = xmlStr; [].forEach.call(xml.querySelectorAll('note[text]'), function (note) { note.setAttribute('text', note.getAttribute('text').replace(/\\r?\\n/g,'@#10')); }); return xml.innerHTML.replace(/@#10/g, '
'); } // I/O var button = document.querySelector('button'); var input = document.querySelector('textarea'); var output = document.querySelector('pre'); // click handler button.onclick = function () { output.textContent = convert(input.value); }
textarea { width: 25em; height: 10em; float:left}
<textarea><main> <head/><body><note text="Load"> <note text="2 Newlines at the end of this newline"/> </body> </main></textarea> <button>convert</button> <pre></pre>
Note that replacing with 
 immediately would result the & to be escaped as & 请注意，立即用
替换将导致&转为& . 。

You want to alter the regex to not be greedy. 您想将正则表达式更改为不贪婪。 Here's a nice article describing it: 这是一篇描述它的好文章：
