C# – HtmlAgilityPack and selecting Nodes and Subnodes

c++html-agility-packxpath

Hope somebody can help me.

Let´s say I have a html document that contains multiple divs like this example:

<div class="search_hit">
    <span prop="name">Richard Winchester</span>
    <span prop="company">Kodak</span>
    <span prop="street">Arlington Road 1</span>
</div>
<div class="search_hit">
    <span prop="name">Ted Mosby</span>
    <span prop="company">HP</span>
    <span prop="street">Arlington Road 2</span>
</div>

I´m using HtmlAgilityPack to get the html document. What I need to know is how can I get the spans for each search_hit-div?

My first thought was something like this:

foreach (HtmlAgilityPack.HtmlNode node in
    doc.DocumentNode.SelectNodes("//div[@class='search_hit']"))
{
     foreach (HtmlAgilityPack.HtmlNode node2 in node.SelectNodes("//span[@prop]"))
     {
     }
}

Each div should be an object with the included spans as properties:

public class Record
{
    public string Name { get; set; }
    public string company { get; set; }
    public string street { get; set; }
}

And this List shall be filled then:

public List<Record> Results = new List<Record>();

But the XPATH I'm using is not doing a search in the sub node as it should do. It seams that it searches the whole document again and again.

I mean I already got it working in that way that I just get the the spans of the whole page, but then I have no relation between the spans and divs. Means, I don´t know anymore which span is related to which div.

Does somebody know a solution? I already played around that much that I'm totally confused now. 🙂

Any help is appreciated!

Best Solution

If you use //, it searches from the document begin.

Use .// to search all from the current node

 foreach (HtmlAgilityPack.HtmlNode node2 in node.SelectNodes(".//span[@prop]"))

Or drop the prefix entirely to search just for direct children:

 foreach (HtmlAgilityPack.HtmlNode node2 in node.SelectNodes("span[@prop]"))
