HtmlAgiltyPack parse HTML and take value out of span tag and class name
asp.net asp.net-mvc c# html html-agility-pack
Question
I download an HTML file using my web request client. And I just want to parse this portion of HTML out of the complete document:
<span class="sku">
<span class="fb">SKU :</span>118880101
</span>
To get this value, I'm using HTML Agility Pack: 118880101
And I wrote something along these lines:
HtmlDocument htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml(html);
return htmlDoc.DocumentNode.SelectNodes("//span[@class='sku']").ElementAt(0).InnerText;
And this gives me the following HTML value:
SKU :118880101
literally, with gaps in between... How can I modify HTML Agility Pack's logic such that I can just remove the value 118880101?
Can someone please assist me?
Edit: This regex might be effective:
Substring(skuRaw.LastIndexOf(':') + 1);
This would entail taking everything in the received string after the ":" symbol... However, I'm unsure whether using regex in this way is secure.
Accepted Answer
Do This
HtmlDocument htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml(html);
var innerText=htmlDoc.DocumentNode.SelectNodes("//span[@class='sku']")
.ElementAt(0).InnerText;
return innerText.replace(/\D/g,'');
if you want to use only Html Agility pack try this
var child = htmlDoc.DocumentNode.SelectNodes("//span[@class='fb']")
.FirstOrDefault();
if (child != null)
{
var parent = child.ParentNode;
parent.RemoveChild(child);
var innerText = parent.InnerText;
}
