我正忙于将文本日志解析为HTML，并用HTML项目符号标记替换选项卡

我需要一个正则表达式来识别一行的开头，然后在它的末尾附加一些东西。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

需要更改为：

<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>附加到行的末尾。

我该怎么做？

您可以这样做：

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);
