the awesomium answering forums seem pretty much dead, so I'm reposting this here
First of all, before starting to learn Awesomium I used the HtmlAgilityPack library for all my parsing needs, but the library is not being updated anymore and I decided to move to Awesomium. (so my approach is based on my experience with HAP)
I figured out how to parse lists of objects with Awesomium, but I can't figure out how to work with them. For example:
public dynamic FindNodes(string xpath, dynamic node = null, WebView wv = null)
{
if (wv == null) wv = mainView;
dynamic nodes = (JSObject)wv.ExecuteJavascriptWithResult(String.Format("document.evaluate(\"{0}\", {1}, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null)", xpath, "document")));
int length = nodes.snapshotLength;
for (int i = 0; i < length; i++)
{
Console.WriteLine(nodes.snapshotItem(i).innerText);
}
return nodes;
}
The problems start after I return the nodes. I want to perform a series of searches for each node, so after returning them I decided that the following should work:
dynamic weakCounters = ap.FindNodes("//div[@id='weaklist']/ul/li");
for (int i = 0; i < weakCounters.snapshotLength; i++)
{
ap.FindNodes("//h3[@class='black']", weakCounters.snapshotItem(i));
}
But it did not. The part where I'm trying to get the length of the list and of course, if I try to get a snapshot of the item directly I get an error.
I understand, that I'm making a HUGE mistake somewhere. I just can't understand where.
Edit: Surprisingly if I do the following, everything seems fine, but it just doesn't look right to create a new variable everytime I need to access it (that's just bananas)
dynamic weakCounters = ap.FindNodes("//div[@id='weaklist']/ul/li");
dynamic nodes = weakCounters;
for (int i = 0; i < nodes.snapshotLength; i++)
{
Also, how can I pass the result (element) that I have extracted back to awesomium so that I could do a "subsearch" ?
