Hi,

I have used following reguest to get image tags and attributes of image.

mshtml.HTMLImgClass imga in HTMLDocument.getElementsByTagName("img")

But this code could not read image tags and attributes of anchor tags under iframe tags.

So Kindly suggest about this issues.

Thanks in advance.

Hi,

You must try to see which frame you should call the getElementsByTagName method.

Say doc is your HtmlDocument object then you can do something like

doc.Window.Frames[index].Document.GetElementsByTagName("img")

here you need to figure out the index or the name of the iframe.

Hope that helps!

Hi vasanthilakshmanan,

Please follow the suggestion kindly provided by Digvijay (Thank you, Digvijay!).

Also check if IE fires several DocumentComplete/DownloadComplete events in your case. Probably, you will find the images in another document (frame).

Hello,

I tried this same code in c#.net,
HtmlDocument.Window.Frames[index].Document.GetElementsByTagName("img"). And also received the same issue as above.

HtmlDocument Object does not show the window property. Can you provide any sample code as you worked or any other examples.

Hi Aswathi, 

private void IEModule_DocumentComplete(object pDisp, string url)
{
    mshtml.IHTMLDocument2 doc = (pDisp as IE.IWebBrowser).Document as mshtml.IHTMLDocument2;
    System.Diagnostics.Debug.WriteLine("!!! " + doc.frames.length.ToString() + " " + doc.url);
}
