Question

我正忙着将文本日志解析为HTML，我正在用HTML子弹标签替换标签

我需要一个正则表达式来标识一行的开头，然后在它的末尾添加一些东西。例如：

config system accprofile
    edit "Number 1"
        set mntgrp read-write
    edit "read-only"
        set mntgrp read

config system 2
    edit "Number 2"
        set mntgrp read-write
    edit "read-only"
        set mntgrp read

需要改为：

<ul>
    <li>config system accprofile</li>
        <ul>
        <li>edit "Number 1"</li>
            <ul>
            <li>set mntgrp read-write</li>
            </ul>
        <li>edit "read-only"</li>
            <ul>    
            <li>set mntgrp read</li>
            </ul>
        </ul>
    <li>config system 2</li>
        <ul>
        <li>edit "Number 2"</li>
            <ul>
            <li>set mntgrp read-write</li>
            </ul>
        <li>edit "read-only"</li>
            <ul>
            <li>set mntgrp read</li>
            </ul>
        </ul>
</ul>

我可以通过搜索'config'来识别每行的前面，但我需要将\n\t<ul>附加到该行的末尾。

我该怎么做？

你可以这样做：

＆＃13;

function myReplaceMethod (text) {
    console.clear();
    text = text.replace(/^(?:\t| {4}){2}(?!\s)(.*)/gm, '\t\t\t<li>$1</li>');
    text = text.replace(/^(?:\t| {4}){1}(?!\s)(.*)/gm, '\t\t<li>$1</li>\n\t\t\t<ul>');
    text = text.replace(/^(?!\s)(.*)/gm, '\t<li>$1</li>\n\t\t<ul>');
    text = text.replace(/(\n(\s*)<li>.*)(?:\n(?!\2\s)|(?![\s\S]))/gm, '$1\n$2</ul>\n');
    text = text.replace(/^/, '<ul>\n');
    text = text.replace(/$/, '\n</ul>');
    text = text.replace(/(\n(\s*)(?:\t| {4})<\/ul>\n)(?=\n)/gm, '$1$2</ul>');
    return text;
};

// ---

var string =
    'config system accprofile\n' +
    '    edit "Number 1"\n' +
    '        set mntgrp read-write\n' +
    '    edit "read-only"\n' +
    '        set mntgrp read\n' +
    '\n' +
    'config system 2\n' +
    '    edit "Number 2"\n' +
    '        set mntgrp read-write\n' +
    '    edit "read-only"\n' +
    '        set mntgrp read';

var output = myReplaceMethod(string);

console.log(output);

Javascript正则表达式在一行中查找表达式然后追加到该行的末尾
