XPATH - 如何提取这个？ [关闭]

Question

OBJECTIVE: Get values of anchor link (some_path) and anchor value (User Name) using only and only anchor ID (msg123456) as starting point.

HTML:

<!-- a lot of HTML code before this -->
<a id="msg123456"></a><a id="new"></a>
<div class="windowbg">
    <span class="topslice"><span></span></span>
    <div class="post_wrapper">
        <div class="poster">
            <h4><a href="some_path" title="some_user">User Name</a></h4>
        </div>
    </div>
</div>
<!-- a lot of HTML code after this -->

PROBLEM: I know how to use XPATH for simple tasks, but in this situation Im not sure from where to start.

Answer 1

Fetch the anchor tag which you can search for, this is still easy. The more difficult part is finding the next div, which you can do using following-sibling::div[1] which fetches the first <div/> following on the same level after the current context. The stuff after that is easy again.

For the path:

//a[@id="msg123456"]/following-sibling::div[1]//a/@href/data()

For the user name:

//a[@id="msg123456"]/following-sibling::div[1]//a/data()
