在 C# 中用 "HTML Agility Pack" 解析未标记为 HTML

Question

使用 HTML Agility Pack，我想解析 HTML 文档中未标记的文本。下一个 HTML 是我将处理的 HTML 结构的示例，最后一个 div 下面的文本是我要提取的文本示例。（以 "I am selling..." 开头并以“...服务或优惠”结尾的那个）

<div class="mapbox">
    <div id="map" class="viewposting" data-latitude="32.965732" data-longitude="-96.882528" data-accuracy="22"></div>
    
    <p class="mapaddress">
        <small>
        (<a target="_blank" href="https://maps.google.com/maps/preview/@32.965732,-96.882528,16z">google map</a>)
        </small>
    </p>
</div>
    <p class="attrgroup">

            <span><b>2012 jeep grand cherokee laredo</b></span>
            <br>
    </p>
    <p class="attrgroup">
            <span>VIN: <b>ask me</b></span>
            <br>
            <span>condition: <b>excellent</b></span>
            <br>
            <span>cylinders: <b>6 cylinders</b></span>
            <br>
            <span>drive: <b>rwd</b></span>
            <br>
            <span>fuel: <b>gas</b></span>
            <br>
            <span>odometer: <b>98000</b></span>
            <br>
            <span>title status: <b>clean</b></span>
            <br>

            <span>transmission: <b>automatic</b></span>
            <br>

    </p>
    
        <div class="print-information print-qrcode-container">
            <p class="print-qrcode-label">QR Code Link to This Post</p>
            <div class="print-qrcode" data-location="east"></div>
        </div>

加载文档后，使用 xpath 选择特定节点后的文本。

const string xpath = "//div[@class='print-information print-qrcode-container']/following-sibling::text()[1]";
string text = doc.DocumentNode.SelectSingleNode(xpath).InnerText;

returns:
