New Post: KeyNotFoundException when searching for "apos"

I hit the following exception:

System.Collections.Generic.KeyNotFoundException was unhandled by user code
  HResult=-2146232969

The key that it was trying to look up is "apos".

Here is the markup originally generated generated by an HtmlRichTextBox that my application was trying to convert:

"<font face=\"Microsoft Sans Serif\" color=\"#000000\" size=\"2\"><p align=\"left\">&apos;</font>"

New Post: how find input of form in html with htmlagilitypack?

evr — Sun, 19 May 2013 18:28:07 GMT

I have a program that you're using htmlagilitypack, which dll's I've added it into the html code of the program, we'll find a form to input.
So explain. Plan to tag form (form) after the detection of the input resulted in him somewhere to put them on the operation took place.
I put the code I ended up doing all the forms and all the cares in the input form, which is mine, and took the game without it's a and there's a I was doing here method.
I come from the input of each form and method which can be determined from the finished work are input form.
Please guide.

my code:
HtmlNodeCollection forms = doc.DocumentNode.SelectNodes("//form");

                    if (forms != null && forms.Count > 0)
                    {
                        FormMethod = forms[0].GetAttributeValue("method", "POST").ToUpper();
                        HtmlNodeCollection inputs = doc.DocumentNode.SelectNodes("//input");
                        foreach (HtmlNode input in inputs)
                        {
                            string TypeName = "";
                            if (input.Attributes.Contains("type"))
                                TypeName = input.Attributes["type"].Value.ToString();


                            if (
                                string.Compare(TypeName, "button", true) != 0 &&
                                string.Compare(TypeName, "image", true) != 0 

                                )
                            {
                                try
                                {
                                    InputsControls += input.Attributes["name"].Value.ToString() + "\r";
                                }
                                catch (Exception)
                                {
                                }
                            }
                        }
                    }

Closed Issue: Throw ArgumentException If Charset Is Invalid [8541]

DarthObiwan — Thu, 16 May 2013 12:33:01 GMT

For a html page like below. charset is empty or invalid string
<html>
...
<head>
<meta http-equiv="Content-Type" content="text/html; charset=">
</head>
...
</html>

Parsing of the document would throw a ArgumentException. This is not user-friendly. It is preferable to have HtmlAgility ignore invalid charset value.

Root cause is in file HtmlDocument.cs, function ReadDocumentEncoding, Encoding.GetEncoding(charset) throws a ArgumentException if the argument is not invalid charset name.

Closed Issue: HtmlNode.XPath Property [12095]

DarthObiwan — Thu, 16 May 2013 12:33:01 GMT

It would be nice to see an XPath property of the HTML Node class that return's a node's absolute xpath.

Closed Issue: OptionOutputOriginalCase is ignored for attributes when not outputting XML [25278]

arsh — Thu, 16 May 2013 12:32:58 GMT

I've been using Html Agility Pack to automatically modify some HTML forms and insert ASP.NET tags into them. I ran into a problem whereby I could specify attributes with names such as "AssociatedControlID", but they would always be output as "associatedcontrolid", even when OptionOutputOriginalCase was set to true. I had a look in the source for the library and the problem appears to be in HtmlNode.WriteAttribute. The check for OptionOutputOriginalCase = true is only carried out if OptionOutputAsXml is also true. I think this option should be checked in either case, and if it is true, the original attribute name used. Unfortunately, I can't switch on XML output, as this causes problems with ASP.NET tag names like "asp:TextBox", so I'm using a modified version of the library to get around the problem for now.

Closed Issue: HtmlNode.Ancestors() method does not include ParentNode [30608]

DarthObiwan — Thu, 16 May 2013 12:32:57 GMT

The HtmlNode.Ancestors() method does not include the parent node in the list of ancestors returned. The first ancestor returned is the grandparent node, then the great grandparent node etc. In other words the parent node is skipped.

/// <summary>
/// Returns a collection of all ancestor nodes of this element.
/// </summary>
/// <returns></returns>
public IEnumerable<HtmlNode> Ancestors()
{
HtmlNode node = ParentNode;
while (node.ParentNode != null)
{
yield return node.ParentNode;
node = node.ParentNode;
}
}

This is inconsistent with the HtmlNode.Ancestors(string name) method, which does return the parent (assuming the name matches the name parameter).

Both overloads of HtmlNode.AncestorsAndSelf also return the parent node.

A simple fix is to initialise the node variable with this rather than ParentNode.

New Post: Paging problem

Hi,

I have a website to scrape which has paging on it. When I use HTML Agility to download the HTML data it always loads first page. But when I paste the same url on browser it just works fine.
Url look like this "http://sampleurl.url/?q=something&page=5"
