Parse A Webpage In Program That Is Written With A Bunch Of Document.write's?
Dec 20, 2011
I am parsing a web page with the HTML agility pack in vb.net and it works great most of the time, but I have come across a site I need help with.
When I go to grab the web page with my http object (I am using chilkat http and it does not have a javascript engine) I get back the page which is poorly written with document.writes for basically the entire page.
I do not want to use the browser control to first render the page.
Do you know of anything that will allow me to parse this page easily with xpath... does xpath work with javascript? Is there a way for me to remove the javascript with the agility pack?

Here is a snippet of an XML file that I need to read with VB.NET[code]...
I am familiar with creating a new XmlDocument and using the Load method to read the file. I know how to get a collection of child nodes and loop through them to get elements and attributes. But in this case, I need to extract all of the data between the two "verse" tags (the starting one with the "sID" attribute and the ending one with the "eID" attribute), including the tags and the data in between as one continuous string. I can loop on the nodes, but I only get the "w" nodes and one final "#text" node for the period, but I don't know how to get the spaces and punctuation between the "w" tags.

I have a function that excepts a Message from MSMQ, I convert the body of the message into a string which represents an XML document. I need to parse through the XML document, grab the values from the nodes and process them. I am having problems using either XDocument of the XMLReader, both of them give me the error "Illegal characters in file". Here is a copy of the XML file as it is deserialized from the message:
<?xml version="1.0"?> <queueOrder xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <InterfaceName>EPN</InterfaceName> <Ingot>U06506L</Ingot>

The program allows users to insert Documents along with a bunch of their attributes into the program. The documents are stored in a relational database. One of the required functionalities is allowing the user to look for such documents. The User normally search directly for the obvious attributes of the document, like a unique ID, or it's Title. The problem is that from the search parameters is not allways known which ones will the user fill. For example the user inserts the name and version of the deocument, another time the user enters part of the Title and the person that delivered the document, or might just enter the document number and nothing else. Some of the data might even be incomplete, like title, name of the person who created the document and so on. The idea from the person who designed the system (I'm only reimplementing it) was to allow easier searches for the user, and allowing the user to search for more parameters tod with the idea that "the more parameters, the more specific results", since the results are always group of documents instead of single documents.

I want to pass an XmlDocument as a parameter to my webservice method. After I have loaded an XML file from a path, when I try to send the XmlDocument as a parameter by webservice method, I come across this error. What can be the reason? I use StreamWriter and I close it. I don't use XmlWriter.The development environment is VS 2008
Error Message:
Cannot write XML declaration. WriteStartDocument method has already written it.
Edit (from comments):I can't post all the code because it has more than 1000 lines. Also when I load Xmldocument in web, I can't use this method without problem. Maybe Webservice causes a problem?
Dim xml As New XmlDocument
xml.Load("My Documents" & xmlfile & ".xml")
myTransfer.Save_XML(xml, 1)

I tried to write a text written in my textbox to file.(a .txt). I scanned it to see if it contained any illegal characters, the program said that it did not. However, when I went to save it it said that the program performed an illegal operation.
System.Runtime.InteropServices.COMException was unhandled Message: Exception from HRESULT: 0x800A0005 (CTL_E_ILLEGALFUNCTIONCALL).
It created the text file but did not write the content of the textbox to the file.I can save the text in Microsoft word without a problem. Is there something wrong with the encoding for the textbox and how do I set the encoding for the characters so I can write it to a text file.

I have a VB.Net app that needs to print a bunch of pages from a secure intranet site; the app was made and was working for a non-secure site but now the app needs to login before accessing the web pages necessary to print. I get the error "Object Reference not set to an instance of an object" when I use my new Sub which follows:
Private Sub SiteLogin()
WebBrowser1.Navigate("http://url/login/")
WebBrowser1.Document.GetElementById("user").SetAttribute("value", "username")
[code]....
This Sub prints the given page in IE, so I figured I could use the same WebBrowser1 object for the login Sub, as I don't know how to or whether I should declare a separate object for the SiteLogin Sub. Both of these functions are called after the WebBrowser1 object is defined however. I just need to be able to submit a simple login form to a set URL, and this info needs to all be hardcoded (there's no option to set the location or login info nor should there be).

how to SetAttribute (a Value) for a textbox in a webpage document that don't have an ID .I already knows that to SetAttribute to a textbox you just need the ID of the element.
I.E : WebBrowser1.document.GetElementByID(THE ELEMENT ID).SetAttribute("Value",TextBox1.text)
So as you see in the example, to set attribute to an Element I need an ID and in my case I don't know what is the ID of the Specific Element.
This is the ViewSource of the Textbox :
<input name="ctl00$ContentPlaceHolder$ccEnterCode" type="text" size="5" maxlength="5" value="">
I don't see where's the ID !

I've recently started programming for Visual Basic Express - 2008, and I'm currently trying to make a program which takes a bunch of inputs (Name, Age, x2 score results) and then turns this into an output at the end which varies depending on the score results.
I've stumbled upon a small hinderance, which is that the very final stage which has a Console.Writeline does not appear after testing the program. So, everything else functions fine, but as soon as it gets past the "Console.WriteLine("All pupils have been calculated, the results are...")" command the program closes itself.I'm not looking for much help, just wondering exactly what is causing this to happen. I also realise that my coding is sub-par and is coded in a slightly odd fashion, but I'd rather just get this one to work and use the mistakes from this one to correct my future work.

VS 2008 VB/I've implemented an interface to a .com program written in c++. I'm trying to access a data structure array(uNewValues) of type PLCCOMMLib.ANALOG_CONTIN. uNewValues should be a datastructure array of several elements (iSigIDCount). My problem is I only get the first array element of the datastructure.I've tried several methods and looked into marshalling but don't understand how to implement marshalling if that is the correct option.
Code below:
Public Sub AnalogContinUpdate(ByVal iSigIDCount

ByRef uNewValues As PLCCOMMLib.ANALOG_CONTIN)
