How To Parse Text Data From URL

Aug 19, 2011

We are using the following code to try to parse some text data from the URL below:
Dim strURL As String = "[URL]"
' *** Establish the request
Dim loHttp As HttpWebRequest = DirectCast(WebRequest.Create(strURL), HttpWebRequest)
' *** Set properties
loHttp.Timeout = 10000
' 10 secs
loHttp.UserAgent = "Code Sample Web Client"
[Code] .....

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.

VS2008 Load And Parse A Text File And Extract Data Between Points On Any Given Line

Apr 4, 2010

I need to load and parse a text file and extract data between points on any given line. I can load the file, but it's the parsing that's giving me headaches. e.g. "Phoned Jim and arranged for John to attend site" First I need to search for "Phoned" because the line always starts with that, and then I need to extract "Jim and arranged for John"

How Best To Parse A Text Log File

Jun 22, 2010

I occasionally have to search a very large text file as a troubleshooting step. The file is continuous text (with spaces between much of the text) but almost everything is date/time stamped. The text is actually messages between two machines so I'd like to insert a line break after every message so that I can follow the protocol exchange. Thre are also a few key words that I'd like to again, separate with a line break.

Parse A Text (log) File?

Jun 2, 2009

I am using VB.NET 2005 (if that matters).I need to parse a text (log) file in which to process lines like:

Program Up at: Tue Jun 24 11:32:53.656 2008 - TerrificProgram.exe
<some lines here which I ignore>
0.00:24:16 - Emergency Stop!
<more lines to ignore>
Program Down at: Thu May 29 22:22:56.000 2008

where the 0.0:24:16 is the offset in TimeSpan format (d.hh:mm:ss) relative to the 'Program Up at" datetime.The 'Program Up at: <date/time>' line I successfully detect (in another function which works) and as a result a set a Boolean flag that I am in a valid <Up> - <Down> sequence and I also set a Start-up DateTime var to which to add the offsets later.

The task is to convert the TimeSpan at the beginning of the 'Emergency stop' line to a regular DateTime expression and to write the converted line to another log-file.Simple, isn't it?The function I use for the above purpose is:

Private Function IsTimeSpan(ByRef InputLine As String, ByVal ProgStart As Boolean, ByVal DTofProgStart As DateTime, ByRef NewDateTime As DateTime)
Dim iLine As String = InputLine
Dim Index As Integer = iLine.IndexOf(" ")

[code]....

What I am doing is I pass each line ('InputLine' parameter) from the original log-file to the function together with the 'in <up>-<down>' flag ('ProgStart' parameter'), the start ot program DateTime (in the 'DTofProgStart') and I want the NewDate to hold the real datetime of Emergency event occurence (not its offset).

What happens is that I successfully detect the lines of interest but the NewDateTime is not updated (though 'ts' is in the correct format and the assignment 'NewDateTime = DTofProgStart' correctly assigns the passed value).Another curious thing is that the line

InputLine.Replace(testStr, NewDateTime.ToString("MMM dd HH':'mm':'ss yyyy"))

does not change the original TimeSpan beginning of 'InputLine' with the regular DateTime (though not updated) in 'NewDateTime'.Why?

Parse(receive) The Data From The PBX Itself?

Parse A Text File By Line?

Jan 20, 2011

I'm running into a problem whenever I try to parse a text file by each line. I know I could use stream reader to read line by line but it is a lot easier to simply use split() and I would also like to know the reason why split() doesn't work.

For example, I created a file "test.txt" and filled it with the following text.

text1
text2
text3

then put the following code in the load event of the form (a button click would work the same).

Parse Delimiter Text File?

Apr 12, 2012

I'm trying to use VB.NET to parse a very large plain text file (2 GB). It is a database and has a field delimiter of SOH and a record delimiter of STX. I want to separate the fields and records of the file.

I would normally read each line of a text file and then use the split function to separate out the fields. I can't use this approach as there isn't always a delimiter on every line.

Is there any way to read a file until STX is found (rather than one line at a time)?

VS 2008 - Parse Through Text And Only Get Certain Matches

Oct 28, 2009

I'm trying to find a good way to parse through text and only get certain matches, like say someone puts the text "My name is Bob" in a textbox, then it puts the text "<Tag>My name is Bob</Tag>" in another textbox, and my problem is, if that person were to put..."My name is </Tag> Bob" in the textbox, when the RegEx match is found, you would only get "My name is" as a match. So how can I make sure that the text input no matter what it is will not interfere with the <Tag></Tag> when using the RegEx:
(?<=(<Tag>).+?(?=(</Tag>))
