Ho caricato l'HTML in un HtmlDocument
. Quindi ho selezionato XPath come submain
. Quindi non so come accedere a ciascun tag, ad esempio h2
, p
separatamente.
HtmlAgilityPack.HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("//div[@class=\"submain\"]");
foreach (HtmlAgilityPack.HtmlNode node in nodes) {}
Se utilizzo node.InnerText
ottengo tutti i testi e InnerHtml
non è utile. Come selezionare tag separati?
Quanto segue aiuterà:
HtmlAgilityPack.HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("//div[@class=\"submain\"]");
foreach (HtmlAgilityPack.HtmlNode node in nodes) {
//Do you say you want to access to <h2>, <p> here?
//You can do:
HtmlNode h2Node = node.SelectSingleNode("./h2"); //That will get the first <h2> node
HtmlNode allH2Nodes= node.SelectNodes(".//h2"); //That will search in depth too
//And you can also take a look at the children, without using XPath (like in a tree):
HtmlNode h2Node = node.ChildNodes["h2"];
}
Stai cercando discendenti
var firstSubmainNodeName = doc
.DocumentNode
.Descendants()
.Where(n => n.Attributes["class"].Value == "submain")
.First()
.InnerText;
