Question

I am trying to parse html page and I am facing a problem which is that I want to get the inner text of a node segmented i.e iterate on html node children assuming each text segment as a in child:

<node1>
This text I WANT on iterate#1
<innernode>This text I WANT on iterate#2</innernode>
This text I WANT on iterate#3
<innernode>This text I WANT on iterate#4</innernode>
This text I WANT on iterate#5
</node1>  

I am using htmlagilitypack as a parser but I think that I will face this problem with any other html parser

Depending on your .NET version, you could use an extension method that works on the node you want.
I havent used the html agility pack, so this is a mix of C# and psuedo-code.

eg

public static List<string> GetTextSegments(this HtmlNode node)
{
    string nodesText = ... // get the nodes text
    yield nodesText;

    List<HtmlNode> innerNodes = ... // get the list of inner nodes with a 
    // query like node.SelectNodes("//innerNodes")
    foreach(HtmlNode iNode in innerNodes)
    {
        string iNodeText = ... // get iNodes text
        yield iNodeText;
    }
}

You could then call this like so:

HtmlNode nodeOfTypeNode1 = ... // 
foreach(string text : nodeOfTypeNode1.getTextSegments())
{
    Console.WriteLine(text);
}
