Converting nested html to bbCode quote tags

问题

I am trying to convert the following html

<div class="bbQuote">
    <div class="quoteAuthor">Joe Block</div>
    <div class="quoteContent">This is the first message<br>
        <div class="bbQuote">
            <div class="quoteAuthor">Jane Doe</div>
            <div class="quoteContent">This is the second message</div>
        </div>
    </div>
</div>

to the following bbCode

[quote=Joe Block]
    This is the first message
    [quote=Jane Doe]
        This is the second message
    [/quote]
[/quote]

How can I do this using jQuery?

PS: Nested HTML can have zero or more children

回答1:

Here's a very basic example:

var html = $('#commentContent').html(),
    beingParsed = $('<div>' + html.replace(/<br>/g, '\n\r') + '</div>'),
    $quote;
while (($quote = beingParsed.find('.bbQuote:first')).length) {
    var $author = $quote.find('.quoteAuthor:first'),
        $content = $quote.find('.quoteContent:first'),
        toIndent = $author[0].previousSibling;

    toIndent.textContent = toIndent.textContent.substring(0, toIndent.textContent.length-4);
    $author.replaceWith('[quote=' + $author.text() + ']');
    $content.replaceWith($content.html());
    $quote.replaceWith($quote.html() + '[/quote]');
}

var parsedData = beingParsed.html();

Fiddle

Limitations:

1. It won't convert other HTML to BBCode (<b>, <i>, anchor tags etc);
2. Indentation/white space is not 100% accurate.

I'd use Ajax to fetch the actual post content from the DB or use a proper jQuery bbCode parsing library.
