Jsoup无法选择输入类

Question

我有这个HTML：

<div class="responsive_friendblocks">
<div class="friendBlock persona offline" href="http://steamcommunity.com/profiles/76561198312248750" data-miniprofile="351983022">
    <div class="manage_friend_checkbox" style="display: none;">
        <input class="friendCheckbox" type="checkbox" id="friendbox_[U:1:351983022]" name="friends[76561198312248750]" data-steamid="76561198312248750" value="1">
    </div>

我想使用Jsoup获取“data-steamid”。我不知道怎么去那里。该代码适用于“data-miniprofile”。它只是没有为“data-steamid”返回任何内容。

这是我的Android代码：

protected Void doInBackground(Void... params) {
    try {
        // Connect to website
        Document document = Jsoup.connect(URL).get();
        Elements MiniProfile = document.select("div.friendBlock.persona.offline");
        Elements IDs = document.select("input.friendCheckbox");

        //Attribute
        PlayerMiniProfile = MiniProfile.attr("data-miniprofile");
        PlayerID = IDs.attr("data-steamid");

    } catch (IOException e) {
        Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_SHORT).show();
    }
    return null;
}
