Question

i have been fighting with this code for a few hours now….

Sample Node for results:

<div class="left vcard" sizcache="1" sizset="32">
        <h2 class="clearfix fn org url" sizcache="1" sizset="32">
            <a id="listItemTitle_11310540" href="/marcali/viragok-viragkuldes/11310540/ANDOK_MATYAS/hirdetes.mtt">ANDÓK MÁTYÁS</a> <a class="removeFromList" href="#">törlés</a>
        </h2>
        <p class="description">

        <ul class="profession" sizcache="1" sizset="34">

        </ul>
        <div class="clearfix margined" sizcache="1" sizset="35">
            <p class="address adr">
                <span>Cím:</span> 8700 Marcali, Petőfi S. utca 11 .</p>

            </ul>
            <div class="contacts" sizcache="1" sizset="38">
                <div class="phoneHolder clearfix" sizcache="1" sizset="38">
                    <div class="dt phone">
                        Telefonszám:
                    </div>
                    <div class="dd phoneValue tel" sizcache="1" sizset="38">
                        <span>(70) 326 2843</span> <a class="clickToCall" onclick="javascript:openECS('11310540');" href="#">Hívja ingyen!</a>
                    </div>
                </div>
                <div class="webLinkHolder" sizcache="1" sizset="39">
                    <div class="dt webLink clearfix">
                        Weboldal:
                    </div>
                    <div class="dd webLinkValue" sizcache="1" sizset="39">
                        <a href="http://www.ezerszirom.hu" rel="blank,nofollow">http://www.ezerszirom.hu</a>
                    </div>
                </div>
            </div>
        </div>
    </div>

And my code:

            results = htmlDoc.DocumentNode.SelectNodes("//div[contains(@class, 'vcard')]");
            if (results != null)
            {
                foreach (var node in results)
                {
                    Response.Write(node.SelectSingleNode("//p[@class='description']").InnerText + "<br>");
                }
            }

the problem ?
since i am iterating over the results, each node should have its own description,
but i am getting the InnerText of the first node.
any idea why?

Answer 1

In XPath, // stands for “recursively search from the root”. Therefore the query doesn’t search from the node you have, but gets the first from the document.

Try this:

node.SelectSingleNode("descendant::p[@class='description']")
