Regular Expression: Parse File Name
Nov 15, 2005I'm trying to take the value of a file input field, parse it down to the file name and write the contents into a table cell.
It works, but my regEx isn't quite right
Can someone tell me what's wrong with it?
basically I need everything from the end of the string to the last
right now the expression evaluates to true, not the string.
Code:
<script>
function storeIt(){
var filePath = document.getElementById('Browse').value;
var fileRegExp = /*.*$/;
var fileName = fileRegExp.test(filePath);
document.getElementById('fileTitle').innerHTML = fileName;
}
</script>
How To Change Line Of Code Using Regular Expression
Aug 19, 2009I'm trying to convert a line using a regular expression. The re I am using is this:
<div><span>·<span>[s*]</span></span>([^<]*)</div>
I'm using the expression in the replace function like this:
html = html.replace( /<div><span>·<span>[s*]</span></span>([^<]*)</div>/gi,'<li>$1</li>') ;
The line of code I am changing is like this:
<div><span>·<span> </span></span>Illness - where a pupil is too ill to leave the house</div>
E.g. it should strip out the code and leave <li>Illness - where a pupil is too ill to leave the house</li>. It works fine here [URL] but when used with the replace command it does not? (I'm trying to convert bullet points from word).
?: In Regular Expression
Feb 21, 2006I have seen lot of reg. expession with ?:
For dummy eg
(((XXX)ddd)ff)
The above expression is modified as
(?:(?:(XXX)ddd)ff)
Although both the above expr. gives same result. (RegExp.match() gives
same o/p), most of the places , i have seen second option.
Yes, but different matches r shown (using RegExp.exec())
Is the second expr. most efficient or in particular scenarios?
Any comments???

Regular Expression To Get The File Name From A URL?
Feb 5, 2009regular express to get the file name from a URL?
It has to be flexible in that the extension can be either 4, 5, or 6 chars (.php, .html, .shtml for example) and needs to cater for and whether querystring parameters exist too.
So, both
[URL]
and
[URL]
The regex should return newthread for both.

Comma Delimited Regular Expression
Dec 7, 2006I need a regular expression that will validate a double quote comma
delimited list where the odd entries are numeric and the even are
alphabetical. Each pair must also be on a separate line. For example:
"1","Peter"
"2","Paul"
"3","Mary"

without the double quotes, numeric/alpha pairing and line return
restriction.
^([A-Za-z0-9]?)+([,]s?([A-Za-z0-9]?)+)*$
Regular Expression To Match Any Spaces
Oct 9, 2007Normally I can write regular expressions decently well but for some
reason I am having trouble getting this to work. I am validating form

space.
Regular Expression To Exclude Lines?
Jul 20, 2005All I'm trying to do is delete the lines which don't contain a particular
string. Actually a filter to edit a log file. I can find and replace a thing
with null, but can't figure out how to find the lines which do not contain
the thing.
Going further, I want to generalize and use a JavaScript variable containing
the decision string, but first I need to worry about the not-within-a-line
problem.

View 2 Replies View RelatedRegular Expression For US Phone Numbers?
Apr 30, 2009Here is the form in question: spraytechDOTcom/download_form.asp I am so close to getting this to work the way that I want, but here is what I am having an issue with: I cannot seem to make it look for the 12 digits that are in the phone numbers that we are going to collect. Ex. 800-123-4567
It doesn't have require 12 characters if there is another way to get the number to validate looking like the example above. Here is my regular expression that I am struggling with:
var re = /[^d-]$/ It seems to block any letters, but it will accept only 1 number. I would really like it to make sure that the phone number is only entered like this: 800-123-4567.
I have looked for days trying to figure this out and have only gotten close.
Regular Expression To Validate Township
Mar 31, 2009I'm trying to validate data in a textbox for township (usually written as 12N or 23S for Township 12 North or Township 23 South). In Utah the townships range from 01N to 15N, and 01S to 44S. The expression "/[0-9][0-4][ns]/i" will allow 01n (or s) through 94n (or s). If I change it to "/[0-4][0-4][ns]/i" to limit it to 44n (or s), I then am not allowing for 05, 06, 07, 08, and 09. I hope the above is not too confusing. I'm just starting to work with regular expressions.

Regular Expression For URL With Optional Domain?
Feb 4, 2010I am creating a regular expression for a URL where the domain name (i.e. .com|.edu etc) is optional. That is both http://xyz and http://xyz.com should be valid. If <.> is present then com|edu|.. will be there; but if <.> is absent then com|edu|.. will not be there. Also there can be any number of <.>, but every <.> will be followed by characters. So in other words the string can't end with <.>, it should only end with [a-zA-Z0-9]. So far I have created the following part -
var url=document.myform.addr.value;
var str="^(http|https)://(([a-zA-Z0-9.-]+)*[a-zA-Z0-9-]+.(com|edu|gov|[a-zA-Z]{2})|[a-zA-Z0-9]+$)";

Regular Expression For File Extension?
Sep 27, 2011The mounds of RegExp data will take me days to sift through can someone help me create a regular expression to find a file extension? (all characters after a period) I have already gotten this far: .+. to find everything before and including the period; and I was hoping to integrate the caret to say everything but .+. But I just can't get it to work.
Note: I will be writing a file to the server with JScript ASP. The file name will be passed to the script that writes the file, and I want to make sure that in addition to removing any possible code from the line being written, that I also prevent an executable file from being created. I will be searching for certain extensions and returning if anything else is found.
