Extract Some Specific String From The Web Script By RegExp?
Jul 27, 2009
My problem is to extract some specific string from the web script by RegExp, e.g:
1. <TD title="ABC - SDC">Home Furniture</TD>
- I want to extract "Home Furniture" from here.
2. <TD><INPUT class=ID="( 8352623 ) Demark" value="( 8352623 ) Demark"></TD></TR><!-- <tr> -->
- I want to extract "8352623" from here, can be any of them.
How can I write a RegExp to match them?
And I am getting one solution but work out in C#, obviously it's not working in VB, so anyone does me a favor to translate them in VB structure...
string pattern1 = @"<([tT][dD])[^>]*>(?<between>.*)(?=</1>)";
string test1 = @"<TD title=""ABC - SDC"">Home Furniture</TD>";
if (Regex.IsMatch(test1, pattern1))
[Code]....

I need to extract the whole string if the string has today's date on it. I have already coded a string that displays today's date in the following format - yyyy/MM/dd And I've coded the parsing links bit, now I need to simply search the Listbox and return the first string with the date. [Code]

i have a log file which contains hundreds/thousands of seperate XML messages and need to find a way to extract a complete xml message depending on the parameters given (values of nodes).My biggest problem is that even though i program a fair amount i have had very little contact with XML or the XML libraries of the languages i use and didnt think that a simple text parsing would be an elegant solution!I am going to attempt this in C# or VB.net

I need to extract specific data from a database. With starting point in this data, I will collect information on the internet. After the information is collected I need to check if this information is already stored in the database, and if not, then add it. This action is being repeated about 500-50000 times each time the procedure is being executed. (not often)
The approach I'm taking seemes sleazy and ineffecient and I was hoping you could point out some places where I might be able to optimize it. I've two open connections at the same time. The first I use to extract data, and it stays open throughout the whole session. The second connection is being used first to check if an entry already exist and if not, to add the data.
The reason I am using two connections is due to the fact that I got a reader bound to the first one, so it is rendered unavailable.
I was thinking that maybe checking if the data existed, and adding it if not, maybe could be contracted into one command execution instead of two. I don't know if it would be possible to do this with one connection only as well, as it seemes more proper.

I have found the above code from the net and it works fine as I would expect. I know this because I have added a put the String StoreFile into a text box and it worked. From what I understand about the code above is that we are reading the file test.txt until we reach the end of the file and we are storing it into a string.
What I would like to do is either:
1. Search the String StoreFile until I find the text of my choice, and then extract the characters around it. See attached txt file.
For example, if I wanted to search for MNAUSD in the attached txt file, I want to grab the values on the line (highlighted in blue) and make them available to my program and ignore everything else.
"MNAUSD",UNITED STATES,US $,M,1.558850,1,1.369850,1.113500,L
I know these files are comma delimited, but I would rather use a regular expressions if possible as I have other files that are not comma delimited, so it would be ideal if I have a regular expressions to handle the search and extract
OR
2. Search the File test.txt LINE BY LINE, until I reach my search text MNAUSD and then extract the same values as above.

I know how to extract an entire page source into VB.NET, but once I do that how do I make VB.NET search the text and return a specific vlaue that is not constant?
Take this line from the page source for example:
<td id="actualPriceContent"><span id="actualPriceValue"><b class="priceLarge">$4.30</b></span>
the text is always constant but the price is not - how do I make VB.NET return the price?

I got the following code from codeproject.com:
Dim objOL As Outlook.Application
Dim objNS As Outlook.NameSpace
Dim objFolder As Outlook.Folders
[Code].....
Now, I got as far as making the default folder the Inbox. What I would like to do is to extend the functionality by retrieving only a specific person's emails and extracting and saving whatever attachments he/she sends. Also, I get the following error when the code reaches the Dim Atmt as Outlook.Attachment part: Public member 'Attachment' on type 'Object' not found. I need this function to retrieve the attachments. I've tried different things, but nothing's worked.

I have a parse from Wikipedia saved in a text file in the following form: The town itself is situated to the south-east of the rock, and overlooks the Palaia Monemvasia bay. A small hamlet with about 10 houses lies to the northwest.The founding of the town and fortress of Monemvassia most probably occurred in the 6th century AD. The town was founded in 583 by people seeking refuge from the [[Slavic peoples|Slavic]] and the [[Eurasian Avars|Avaric]] invasion of Greece. From the 10th century AD, the town developed into an important trade and maritime centre. The fortress withstood the [[Arab]] and [[Normans|Norman]] invasions and conquests in 1147. Cornfields that fed up to 30 men were grown inside the fortress.What I need to do is to extract specific texts from the parse given the header names. For example, if I type in a textbot Geography I need ONLY the geography text returned.

"_anim(d+)$"
Ok, with that, I can check for any string that has the _anim suffix alright.
But I need to get the value inside the parenthesis (which I expect to be an integer). And I will also need to get the value before the _anim prefix (which I expect to be a string).
That is what I don't get: how do it "get" values, instead of just "knowing" there was a match?

For the past 2 days i have been trying to come up with a simple solution for this problem, but i have turned up nothing so far.[code]What i am thinking now, is if there was a way to get the "name" and "value" field with the 1 regular expression, instead of having to do the 2, would that be possible?

I have 2 strings:
"This is number 123456789"
"This is number 123456"
I want to match the last number "123456" and replace this. Not the first number because the length is > 6 digits. I have this regex "d{6}" but then he will match the first number also.

Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything

I am struggling to find a solution in string manipulation - I am trying to extract a certain part of the string element after the '=' character - say for ex. dim s as string = "/mysite/secondary.aspx?id=1005"
I am trying to get the string after the "=" and just to grab the 1005. I tried indexof and split, but i am not sure where i am going wrong.
