I'm trying to parse data from the web, basically, from an API rl...How do I approach this? Could I use XMLDocument to do this or MSXML2? [code]I've only worked where the node root doesn't have the name of the thing I need. So, how would I specifically retrieve the data for the node symbol? [code]

View 3 RepliesI am trying to parse a file generated by LGA Tracon that lists the position data for aircraft over a given time frame. The data of interest starts with TRACKING DATA and ends with SST and there are thousands of entries per file. The system generating the file, Common ARTS, is very rigid in its formatting and we can expect the column spacing to be consistent. Here is an image to preserve the exact formatting Here is a reduced text file.

The problem is that the response we are getting in code is incomplete when compared with what actually renders in the browser. The html we are getting shows a javascript function in the body of html where what we really want is the result of the function, which includes the data we need to capture. This is confirmed by loading the page in Google Chrome, clicking on the text "100360" and choosing "inspect element" which allows us to see the full page response with the data we need, specifically the following line:
<pre class="pre-longText-wrap">100360</pre>
How to get this "raw" page response? It may be that the script is taking a few seconds to respond and that we are only seeing the initial page response.

have to write a program/application (which I already started in VB.NET 2010) that connects through Panasonic KX-TEM824 PBX machine via RS232 port (cable already connected : COM15/16 depending on USB I connect) and while it's connected to parse(receive) the data from the PBX itself, data that has caller ID, time of call started and ended, duration of the call and etc. I have found some already application on the Internet that does the work but they are free to try after awhile requires to buy or restart the app again. But I assume there's not much to implement on the code side.

In VB.NET 2005, what is the best way to retrieve and parse HTML data from a URL, a bit like a search engine crawler?I am building an app, where I need to parse a website, and collate data from it (the website uses some tags that I could pull out to get the appropriate bits of data). I want to be able to do this in a thread, and just update a DB with the data, and give the client app a status update of the progress.
View 6 RepliesI have a text reader and I wish to parse the readline string data in double.[code]...
I do not necessarily wish to define the split to interpret double space as separator as I do not know whether this is always the case. I would rather like to tell the program that there are three double format numbers -> go and parse.
is there a way to parse data from a command line tool such as netstat -b 2?

As you can see there are 14 numbers. To make things worse numbers like 19 and 20 are replaced by images and numbers lower than 6 have a span class.
I have a List(Of Byte) that is filled with bytes from the serial buffer on a SerialPort.DataRecieved Event. I then try to parse the data. Part of the parsing process involves deleting elements of the List(Of Byte). Should I be concerned about the List being modified by a DataRecieved Event that might be raised during the parsing process? I realize that probably depends on what I'm trying to do, but, assuming I should be concerned (e.g., the parsing process needs List.Count to not change until parsing is finished), how should I go about making sure any Add calls wait until the parser is done? I guess the answer is something like SyncLock, but I've never really understood how SyncLock works.
View 1 RepliesI have an XML file that I need to parse to generate a few reports. What needs to be done is pretty simple, but I have no clue where to start with parsing the XML.The application will do this:Click a button to browse to an XML file where the format is static. Once the file is loaded, parse the file and generate a report using specific fields from the XML file. Criteria will be based on State(completed or incomplete), activity(Inspection, sample, etc). Here is 1 record of the XML file. Each consecutive record uses the exact same format.

I'm stuck with .Net Framework 2.0, so no Linq or lambda expression goodies for me. Also I want to include the code in my custom library and not just reference it. Can anyone point me to some good library or code.
I just need to parse and not evaluate the expression and find what tokens are in use. After finding the tokens I need to change the expression string before parsing, like if the function ORGVAL is used then the parameter passed has has to be prefixed by an underscore. Like ORGVAL(BAS) will transform to ORGVAL(_BAS). Some functions can have tow parameters like ORGVAL(BAS, "2012/12/31") and this will transform to ORGVAL(_BAS, "2012/12/31")
NOTE: IF THERE ARE OTHER WAYS OF DOING IT PLEASE LET ME KNOW. I WOULD LOVE TO AVOID A PARSER AND LEXER.

I have an app that the user selects information and it writes to an XML file. The user can increase and decrease the information in the XML file so it is dynamic. The other app reads the xml file and uses it to complete tasks. Since the XML is dynamic my code needs to account for that. Right now I have only allowed the XML to have up to four values in a certain node, I would like to allow more but I will need to increase the Select Case function.[code]

I may be getting in way over my head, but here it goes. I am developing a small application for use on a helpdesk. The application will be installed on the client pc's and will be used primarily by the end user to assist the technician on the phone if the user's pc is offline or inaccessible. One part of the application gives the user their IP address, DNS address, DHCP address, and gateway address. I have it to where it will put all of those in the corresponding fields inside a form, but it does not work correctly outside of a domain. Outside of a domain it only gives the IP address. I am sure it is probably how I coded it, but I cannot think of any other way to get that info in a user friendly way. Is there a way to parse a command prompt command to specific fields inside of a form such as the command ipconfig /all?
