Sep 27, 2010I'd like to know one (or more) ways to parse the HTML page output. I'd like to detect some patterns on the HTML that will be send to the client and log some info if present.

View 2 RepliesI am attempting to parse the XML output from a REST web service and have been pointed in the direction of using Linq2Xml to query the XML for the attributes that I am after. The XML output is as follows:
<?xml version="1.0" encoding="UTF-8"standalone="yes" ?>
<Response Status="OK">
<Item Name="NumberZones">2</Item>
[code]...
The returned datatable is empty, I have confirmed that result does have the XML assigned, and result.value is the string version of the XML file (200Westralia0{81C56183-31DA-45C2-90C3-81609F01B38B}Lounge10001{eac0109e-0090-a992-7fba-dc67fe29e6e7})Is anyone able to provide assistance in how I can read from the REST XML example above the name (ZoneName%) and the attribute value (Westralia and Lounge)?
I have a window service that at a particular time sends a fax to the destination.The requirement is that the fax content should be in the specified format. The fax data also contains some dynamic data that is retrieved from the database. According to my understanding i need to write all the data to an html page and then convert into a pdf file and then send the fax.
The problem here is that how to create a html page through code. even if the html page is created how can i convert its output to pdf?As the browser is not involved in this case.
I'm trying to create an ASPX page that displays both an HTML message ("Please wait, your file transfer will begin momentarily") and also commence transmitting a file. I'm trying to avoid making the user open the page, and then clicking a Download buttonIt seems like this may be possible with a "Multipart/mixed" MIME type. Elsewhere I think I read that ASP.NET won't support this.

I've inherited (no pun intended) an old ASP.NET 1.1 project that is now .NET 3.5. It is designed with base class that inherits from PageBase. All of the subsequent aspx pages inherit from this custom pagebase. It currently works by generating a bunch of html text in LiteralControls for the headers and navigation bars and dropping it into an HtmlGenericControl (in this case called 'page'), which is then displayed on the page by using this.Controls.Add(page); This actually works, except for the following output:
<span>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
...
</html>
</span>
Those span's aren't supposed to be there obviously, but they come from the HtmlGenericControl, which defaults to a tagName of span. This is causing some strange behavior in IE regarding centering controls on the page.
Basically I know I should be using masterpages for this type of thing, but I don't have time to switch this all over, and I'm not an ASP.NET expert yet to where I know exactly how to solve this problem. Is there another way of sending literal text directly to the HTML output without wrapping it in a control? Obviously I need the DocType to be the first thing on the page; nothing wrapping it.
The question is not really about parsing the HTML, but rather parsing the HTML and adding elements to the DOM according to the HTML tags. For example - I want to be able to take an HTML page, add attribute to the HTML tags - such as "class='replace'", put some PHP/ASPNET code in the page (make an ASPX page with ASPNET or put some include with PHP) and make them parse the page every time it is accessed and manipulate the DOM of the tags marked as 'class="replace".
For example if I have < div class='replace'>< /div>, after I run the script I'll get something like < div class='replace'>This is a new text< /div>

View 5 RepliesI am creating a web app in ASP.NET with VB code behind. I would like it so that a user can input a url ("[URL]") and then when the user presses the GO button, I want the system to interprete the [URL] page (without navigating to it), look in the HTML source, and store all data that is present within the URL's <p></p> tags...is this possible?
I have noticed a similar thing present on [URL]. When you submit an article to [URL], it automatically looks at the URL's <meta name="description" content="" /> in the URL HTML file. I would like to do a similar thing, but instead extract all text between all <p></p> tags.
I'm trying to parse a HTML file to retrieve certain info in my asp.net app. I've looked at the html agility pack but found that also quite difficult. :-) As my HTML should be pretty standard I'm hoping regex is quick and easy. I need a regex that will look through the html file (which I've loaded into a string) and find the below line and take out the DATATOEXTRACT (which will be some sort of text, the name of a recipe in this case) so I can put it into a variable:
<span class="titleText1">DATATOEXTRACT:
</span>

View 1 RepliesI would like to know which CODE, Classes could be useful for creating a WEB APPLICATION that could:
01 - Connect to an HTML file on the web.
02 - Parse its content (text content).
03 - Find out specific content in a page (for example looking for specific keywords).
Also how to implement:
04 - How to submit information programmatically in HTML page (feeling forms).
I am interested in understanding Classes and general practice and CODE for accomplish this task.
I have successfully been able to parse HTML from a website:
TestParser parser = new TestParser [URL]
List<Pairing> pairings = parser.ParsePairings();
DBSave.SavePairings(pairings, userID);
----------
This works. Now I have to submit a form via C# code.... DONE. It works. And my C# code saves the "new" HTML to a string variable called "submitParsedHTML". My question is: how to I change out the URL, to go through the string variable instead? I am thinking about doing this: When the user clicks the button to "Post" to the form and the app grabs the HTML. The app logs into my FTP account and saves the HTML as a seperate (temporary) file to be used on the internet [URL] Then the app can then parse the HTML as if it was a normal HTML document and not have to go through formatting the text to an HTML document. What do you all think?
I'm very new to ASP.net. I have a c# content page, in which I want to inset this code half way down within the HTML:
<%
HttpResponse r = Response;
r.Write(HttpContext.Current.Request.ServerVariables["SERVER_NAME"]);
%>
But when I view the page, this content comes out first, before even the tag.
how to get this code inline instead?
I was wondering if there was an easy way to change the output generation properties of the HTML editor.
I need to change it from the current XHTML standard (spans, etc) to legacy styles; <b>, <u>, <i>, etc.
Recently I started a project and added a HTML file in it. I modified the HTML file and run it in Visual Studio to see the output. When I tried to validate the HTML file, I found some strange characters got appended. This is quite annoying, although I am not able to see those unexpected characters, I wonder what is the cause of the problem. I didn't adjust anything in control panel of the IIS server, I didn't modify the Web.config file. I tried to add another HTML file and put the same content into it, the same problem occured. Could someone tell me how should I troubleshoot the problem?
View 7 RepliesI am developing a webiste in ASP.NET. On one of the pages page named menu.aspx, with the help of a certain login, I am getting the output in this format
foo({"1":"Jeff","2":"Mik","5":"Tom"});
I am using this code to get the output on the JSON form.
[Code]....
However, I must get the output only in simple JSON on the page without any HTML.
For eg: Here's the screenshot showing the source of the output page. [URL]
Notice that it has only the JSON string as the output.
And here's the screenshot showing the output page source (with HTML). [URL] .This HTML is what I have to remove. How can do I do this? The full code of menu.aspx.cs is putup here. [URL]
Idealy i would like to get a web-page that looks like the popup-windows that you get in Visual Studio when you click an object while debugging. So if the object contains any arrays, i'd also like to see what's in them, and for all those objects inside i would also like to be able to go deeper into those objects.
The reason i'm asking this, is that I can't debug my code locally (because it uses a web-service that will only run on the production), and I can't install Visual Studio on the production server, So i need to be able to actually debug on the production server. I can write my code locally though, and upload it to the production.
i query a database for retreiving all the columns. I will probably have many rows. Im trying to output the query results into an html table. This is what i have so far:

How could i store the many rows and output them using html as soon as i open a page?
How can i redirect the Output of a View to html or string or PDF?
[Code]....
I whant to redirect that action to a pdf but all code i have found is on c# and i cant get it to work.
Is there any .net library which would convert a HTML output to PDF --- in an asp.net application.Doesn't matter if it is free or not
