In the context of functional programming, a typical example of a side effect is "launch the missiles". I was just wondering where that expression comes from historically.

Hi,

This Validator not disciplined even to unknown regular expression!!
Do you know about this problem?
Many thanks!!!
I'm retrieving an unformatted String from a twitter feed. I want to be able to turn a text URL (http://blah.com/qwerty/) into a link but don't know how...is there a handy regular expression for this?
I have an XML feed that looks something like this (excerpt):
<channel>
<title>Channel Name</title>
<link>Link to the channel</link>
<item>
<title>Heading 1</title>
<link>http://www.somelink.com?id=100</link>

That's the rough of it. I'm using this piece of PHP (excerpt):
$xml = simple_xml_load_file($xmlFile);
$xml->xpath($pattern);
Now I want to get all ITEM-nodes (with their children) based on that pesky "domain" attribute in the category node, but no matter what I try it does-not-work.
The closest I got was "//category[@domain= 'http://www.somelink.com/?category=4']"
The expression I tried gave me this result:
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[domain] => http://www.somelink.com/?category=4
)
[0] => Category 1
[1] => SimpleXMLElement Object
(
[@attributes] => Array
(
[domain] => http://www.somelink.com/?category=4
)
[0] => Category 1
The expression should contain all childrens of the two items in the example, but as you can see only the info in the category node is present, I want all the item nodes.
Any help would be highly appreciated.
Is there a specific way to check for a specific integer within a switch statment.
For example.
$user = $ads[$i]->from_user;
To check for the number 2 as $i in the above expression.
I've got a document containing empty lines (\n\n). They can be removed with sed:
echo $'a\n\nb'|sed -e '/^$/d'
But how do I do that with an ordinary regular expression in perl? Anything like the following just shows no result at all.
echo $'a\n\nb'|perl -p -e 's/\n\n/\n/s'
Can you explain this?
I want to eval values and calculations from two different sources. One source gives me the following info(programmatically):
'a = 2'
The second source gives me this expression to evaluate:
'a + 3'
This works:
a = 2
eval 'a + 3'
This also works:
eval 'a = 2; a + 3'
But what I really need is this, and it doesn't work:
eval 'a = 2'
eval 'a + 3'
I would like to understand the difference, and how can I make the last option work.
Thanks for your help.
I'm writing a program which needs to traverse a set of directories. Tried to use the following code:
file.eachDirMatch(/.*[^.svn]/){
//some code here
}
But that ended up match none of my directories. I realize this boils down figuring out the right regex hang head in shame but even after revisiting some Java Regular Expression documentation I thought this should work.
I have created a dataset with fields "LastRunBuild" and "project" .The LastRunBuild field contain string of data seperated by commas according to each project. But Some Projects have no value in LastRunBuild field.When i am using this expression

nothing,Split(Fields!LastRunBuild.Value,",").GetValue(3)) "
a #Error value returns every time. Please reply...
Hi all!
I can use getFunctionNameExpression() to get the function name as a expression. But i don't know how to get the name string from it. Any help ? thank you very much.
I'm trying to write a regular expression that finds C#-style unescaped strings, such as
string x = @"hello
world";
The problem I'm having is how to write a rule that handles double quotes within the string correctly, like in this example
string x = @"before quote ""junk"" after quote";
This should be an easy one, right?
I am parsing table information from the html table.Now I want to check whether there is date in the records for one particular column.Means I want to check whether there is date in the string or not .And date can be in different format like the string can be
FUTIDX 26FEB2009 NIFTY 0 -- There is date in the string.
FUTIDX MINIFTY 30 Jul 2009 -- There is date in the string.
FUTSTK ONGC 27 Mar 2008 -- There is date in the string.
What should be the regular expression for that ?
Hello, is there a good regex expression that would be able to compare two dates
like 3/27/2010 to 3/8/2010 to tell if the first date is greater then the second date?
I'd like to compare using javascript
I'm able to retrieve the URL of a publisher only if their URL is in the title or the description using regular expression in linkshare's coupon API but in doing so, that leaves me with a lot of publishers not having a reference to their website which I need for the type of site that I am building.
I was wondering if anyone else knows a way to reference the publishers URL preferably by their publisher ID or some other way?
I want to turn something like this
CS 240, CS 246, ECE 222, ... (more or less); Software Engineering students only
into
('CS 240', 'CS 246', 'ECE 222', 'ECE 220')
in Python, code that matches a single course looks like
>>> re.search('([A-Z]{2,5} \d{3})', 'SE 112').groups()
('SE 112',)
I prefer a regular expression only method because I have a bunch of other alternate reg exps using '|' to combine them. However, a method with split is acceptable.
I have a dictionary:
D = { "foo" : "bar", "baz" : "bip" }
and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz":
R = { "baz" : "bip" }
what I'v got now is:
R = { k : D[k] }
But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option.
What I'm looking for is a better (cleaner) way to do this.
I am trying to check if a html document includes script tags that are not empty using regular expressions. The regular expression should match any script tag with a content other than whitespaces or linebreaks.
I have tried
<script\b[^>]*>[^.+$]</script>
but this regex only finds script tags with one space.
I'm trying to use python to copy a tree of files/directories.
is it possible to use copytree to copy everything that ends in foo?
There is an ignore_patterns patterns function, can I give it a negated regular expression? Are they supported in python?
eg.
copytree(src, dest, False, ignore_pattern('!*.foo'))
Where ! means NOT anything that ends in foo.
thanks.
I'm trying to get this expression to work, I'm pretty sure its not the parenthesis because I counted all of them. Perhaps there something I'm doing wrong involving the parameter pow (x,y).
double calculatePeriodicPayment()
{
periodicPaymentcalc = (loan * ((interestRate / yearlyPayment))) / (1-((pow ((1+(interestRate / yearlyPayment)))),(-(yearlyPayment * numOfYearLoan))));
return periodicPaymentcalc;
}

When load in Firebugs, it gives me this error:
TypeError: $(".open_gene").on is not a function
[Break On This Error]
$(".open_gene").on('change', function(event) {
However, if I type in this expression in Firebug's console, it can be evaluated as a function without any problems:
>>> $(".open_gene").on
function()
I was wondering what might be the reason to cause this issue.
Does anyone have ideas about this? Thanks!
Given the following text:
This is!!xa simple string!xpattern
I would like to get a regexp that matches the !x that's between "string" and "pattern" but not !!xa that's between "is" and "a".
This regexp is to be used inside a string split().
I have tried several combinations but I cannot get a regexp that meets my needs. Perhaps my expression is not so regular after all =)
Thanks in advance!
I simply want to include a row number against the returned results of my query.
I found the following post that describes what I am trying to achieve but gives me an exception
http://vaultofthoughts.net/LINQRowNumberColumn.aspx
"An expression tree may not contain an assignment operator"
In MS SQL I would just use the ROWNUMBER() function, I'm simply looking for the equivalent in LINQ.
