I need a regexp function which makes a match when the string contains <img...AND the img tag above dows NOT contain a certain path Here is what I have:
<imgs.*(src).+>
This matches if my string contains "<img .....src.....>" (the dots can be anything, I dont care). However, after the "src" part and before the ....
I am trying to figure out how to set up my reg exp search so that the search
will only match on the exact word.
Here is the current problem code:
Word1 = "RealPlayer.exe"
Word2 = "Player.exe"
RegExp re = Word2;
if (re.Find(Word1))
{
bFound = TRUE;
}
Currently the bFound is set to TRUE since "Player.exe" is found within
"RealPlayer.exe". But I only want bFound to be TRUE is if the entire word
matches.
Is there a way in a regexp to *not* match a fixed string value?
Using [^blah] gives matches to anything not containing *any* of letters
b,l,a and h. Whereas I want to match anything that does not containing
the exact string 'blah', i.e. *all* the letters.
Possible?
Can someone please let me know what this matches - i can work out some but not all code...

View 4 Replies View RelatedI have this string: this is my test <a href="yay.html">yay</a> and want to just match the part before the <a...: this is my test I can't figure out the regular expression for this. I've tried everything I can think of. It seems that it needs to do a non-greedy search on the first < it finds, but nothing works, like: ((.*<)?)
View 2 Replies View Relatedthis will match any instance of a number following a letter/[a-z][0-9]/gmiso thatvar str="abc123 456";alert(str.replace(/[a-z][0-9]/gmi,''));would return "ab23 456".
how would i replace just the number? so as to get back "abc23 456" - or ideally "abc 456" ?
why I get an array containing [xml, xml]
Code:
str = 'index.xml'
re = RegExp( /([^s./]+)$/ ) ;
str.match(re) // -> [xml, xml]
I only need xml, not an array, and especially not [xml, xml]
Update: thnx mrhoo, thats clear now!
how can I do a multiple replaces without using regexp? Right now I just have a while that keeps checking if it exist, then if it does, replacing it. Not very efficient.
View 14 Replies View RelatedIs there a way to get the position of multiple substrings that match a

themselves, not the positions, and search() seems to only return the
first position. Here's what seems to work (under Shanti Rao's jsdb.exe

View 5 Replies View RelatedHow can I check if a number exists by itself in this string by using
the RegExp object?
var mystring = "11,111,01,011";
var match = "1";
var re = new RegExp( match );
var isFound = re.test( mystring ) );
Running this code returns 'true' which is not what I want since number
one doesn't exist by itself. I need to use the "match" variable since
it will change depending on user input.
I can only get it to work without variables in the expression. E.g.
var re = new RegExp( /1/ );
Here is my code:
<script type="text/javascript">
var str="Welcome to Microsoft! Microsoft Microsoft";
var stringToBeFound = 'Microsoft'
var ReplaceString = 'site'
document.write(str.replace(stringToBeFound , ReplaceString ));
</script>
My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database
I am doing some maintenance work on a classic asp web page that displays product information. I am changing how the page looks up the available quantities for the various sizes. The old method used several SQL queries to determine the number of sizes and available quantities and then used those results to build a table on the fly on the page.
My modification consists of a web service that consolidates product size availability from three different sources and delivers the data via an XML formatted return. I have also added DOM tags in the table that is built on the fly that identify each entry with the product id and size. So, for a product that has an ID of "P12345" and a size of "XXL," that corresponding cell in the table gets an id tag of "P12345_XXL."
My jQuery update statements worked just fine using this approach until the sizes included decimal numbers. My example for this is shoe sizes. A size represented by an integer (6,7,8,...,15,16,17, etc.) works fine. A half-size represented by a decimal (6.5, 7.5, 8.5,...) does not. Even though the period is contained within a string value, jQuery doesn't seem to be able to match the value with an id tag - and yes, I have verified that the two (the string that I am giving to the jquery select and the actual tag) do indeed match.
So far, the only work-around that I have come up with is to multiply numeric sizes by 10 and parse as integer values. Is this a "known issue" and is there a more elegant solution topursue?
I'm trying to create a script where all the hyperlinks in a page will be replaced with a new set of coding before it. (e.g: a href="this.htm?http://www.google.com").
My code generates this change through a series of random numbers and only runs the script when "2" is the generated number (out of 12). Now, I only know how to replace all occurrences of "href" in all "a" tags, but there are times when I use Javascript to launch new windows or even javascript to navigate to the top of a page.
I tried to use a string match method to search for occurrences of "javascript:" and so forth, but I can't seem to get it working. Code:
How do I extract "somestring" only? I'm on IE7.
<script type="text/javascript">

alert(full);
var inside = (x.match(/(H:(.*))/)); // produces "(H:somestring),somestring" .. I only
want "somestring"
alert(inside);
</script>
How would i use a wildcard in String.match()? For example, I would like to see if a variable contains www.*.com, where the * can be replaced with anything. How could i go about doing that?

I am trying to do a pattern match and check something in a condition but cant get it to work. The first value changes and I need to check and do something if I get a hit on it.

if (mydata.indexOf("first") == "something")

What regular expression will match ANY string that has 10 digits in it?
View 24 Replies View RelatedI wanted to only match in the middle of a string
I have a string = " sdfasf 23234"
I wanted to get the numbers like /([0-9]*)/
But this fails and returns nothing because the string begins with letters. Instead I had to do /[a-zA-Z ]*([0-9]*)/
If that's the case then, why do we bother with something like
/^[a-zA-Z]*([0-9]*)$/
The pattern is already assumed to start at the beginning of the string
I'm trying to perform a very simple validation of user input. I
want to verify that the user entered a six-digit string consisting
entirely of numbers. So anything from 000000 to 999999 is considered
valid. The problem that I'm having is getting the validation to work on
the entire string. In other words, 000000 is okay but 000000000000 is
also returning as a match. Here's a quick code block...I have something
along these lines....
/*********************/

That is failing when I enter 123456 into the textbox. Why, though? I
know I can replace...
if (sNumberValue.match(/A[0-9]{6}z/))
....with something like...
if (sNumberValue.length == 6 && sNumberValue.match(/[0-9]{6}/))
....or I could assign a maxlength to the input box, of course. The thing
is, I really want to know WHY the regular expression isn't responding
as I'd expect. Is there a syntax error somewhere in the code?
Is there way to only match on strings starting with the first characters input?For instance, if I have a list as such:[ 'Tamara','Amy']when I start to type 'Am', I only want to see "Amy" in the drop down list, not "Tamara".I feel like this should be an easy configuration option or easy mod, but alas, I could not find it.
