To get text after the tag, containing another text

For example:

<p>
<b>Member Since:</b> Aug. 07, 2010<br><b>Time Played:</b> <span class="text_tooltip" title="Actual Time: 15.09:37:06">16 days</span><br><b>Last Game:</b>
<span class="text_tooltip" title="07/16/2011 23:41">1 minute ago</span>
<br><b>Wins:</b> 1,017<br><b>Losses / Quits:</b> 883 / 247<br><b>Frags / Deaths:</b> 26,955 / 42,553<br><b>Hits / Shots:</b> 690,695 / 4,229,566<br><b>Accuracy:</b> 16%<br>
</p>

I want to get 1,017. It is a text after the tag, containing text Wins:.
If I used regex, it would be [/<b>Wins:<\/b> ([^<]+)/,1], but how to do it with Nokogiri and XPath? Or should I better parse this part of page with regex?

Here

doc = Nokogiri::HTML(html)
puts doc.at('b[text()="Wins:"]').next.text

Use:

//*[. = 'Wins:']/following-sibling::node()[1]

In case this is ambiguous (selects more than one node), more strict expressions can be specified:

//*[. = 'Wins:']/following-sibling::node()[self::text()][1]

Or:

(//*[. = 'Wins:'])[1]/following-sibling::node()[1]

Or:

(//*[. = 'Wins:'])[1]/following-sibling::node()[self::text()][1]

I would use pure XPath like:

"//b[.='Wins:']/following::node()[1]"

I've heard thousand of times (and from gurus) "never use regex to parse XML". Can you provide some "shocking" reference demonstrating that this sentence is not valid any more?

You can use this XPath: //*[*/text() = 'Wins:']/text() It will return 1,017.

About regex: RegEx match open tags except XHTML self-contained tags
