please rescue me from this regex nightmare.
Claim Code:
7241B-2HWRXR9-2P2BA
$1.00
I'm trying to assign it to a variable in php but all the regex and preg_replace i've tried doesn't help me pull out exactly what is in the middle which is: 7241B-2HWRXR9-2P2BA
any kind of help I can get on this is greatly appreciated!
The problem is a little challenging because I want to code it using std::regex believing it would be easier to read and faster to write.
But it seems that I can only code it one way (shown below).
Somehow my mind could not see the solution using std::regex.
How would you code it?
Would using std::regex_search do the job?

I am writing a crawler to get certain parts of a html file. But I cannot figure out how to use re.findall().
Here is an example, when I want to find all ... part in the file, I may write something like this:
re.findall("<div>.*\</div>", result_page)
if result_page is a string "<div> </div> <div> </div>", the result will be
['<div> </div> <div> </div>']
Only the entire string. This is not what I want, I am expecting the two divs separately. What should I do?
I have sequence files and barcode files. The barcode files may have barcodes of any length that look like "ATTG, AGCT, ACGT" for example. The sequence files look like "ATTGCCCCCCCGGGGG, ATTGTTTTTTTT, AGCTAAAAA" for example. I need to match the barcodes to the sequences that contain them at the beginning. Then for each set of sequences with the same barcode I have to do calculations on them with the rest of the program (which is written already). I just dont know how to get them to match. Ive went through using print statements and The part where it is messed up is the "potential_barcode = line(:len(barcode)" line. Also, where it says #simple to fasta that is where I should be reading in the matched sequences. I'm pretty new at this so I probably made a lot of mistakes. Thanks for your help!
bcodefname = sys.argv[1]
infname = sys.argv[2]
barcodefile = open(bcodefname, "r")
for barcode in barcodefile:
barcode = barcode.strip()
print "barcode: %s" % barcode
outfname = "%s.%s" % (bcodefname,barcode)
# print outfname
outf = open("outfname", "w")
handle = open(infname, "r")
for line in handle:
potential_barcode = line[:len(barcode)]
print potential_barcode
if potential_barcode == barcode:
outseq = line[len(barcode):]
sys.stdout.write(outseq)
outf.write(outseq)
fastafname = infname + ".fasta"
print fastafname
mafftfname = fastafname + ".mafft"
stfname = mafftfname + ".stock"
print stfname
#simp to fasta#
# handle = open(infname, "r")
outf2 = open(fastafname, "w")
for line in handle:
linearr = line.split()
seqid = linearr[0]
seq = linearr[1]
outf2.write(">%s\n%s\n" % (seqid,seq))
# handle.close()
# outf.close()
#mafft#
cmd = "mafft %s > %s" % (fastafname,mafftfname)
sys.stderr.write("command: %s\n" % cmd)
os.system(cmd)
sys.stderr.write("command done\n")
I have download a web page and I want to extract all the links in that file. this links include absolutes and relatives. for example we have :
<script type="text/javascript" src="/assets/jquery-1.8.0.min.js"></script>
or
<a href="http://ift.tt/gbk8l4" />
so after reading the file, what should I do?
I have implemented recursive descent and PEG-like parsers in the past, where you could do things like this:
Path -> Segment+
Segment -> Slash Name
Segment -> /
Name -> /\w+/
Slash -> /
Segment+ means "match one or more Segment"\w+How do you typically accomplish this same sort of thing with LR grammars/parsers? All of the examples of LR parsers I have seen are very basic, such as parsing 1 + 2 * 3, or (())(), where the patterns are very simple and don't seem to involve "one or more" functionality (or zero or more with *, or optional with ?). How do you do that in an LR parser generally?
Or does LR parsing require a lexing phase first (i.e. an LR parser requires terminal and nonterminal "tokens"). Hoping that there is a way to do LR parsing without two phases like that.
ATS(inline, const, unused)
OTS(inline, const, unused)
I'm trying to match inline, const, unused keywords only in ATS macro. i tried ATS([^,]*) but it only matches inline keyword.
I tried now for three hours to construct the following regex match without much success. I have the following two strings:
This is a test string to illustrate the problem (example) in complex matching logic (Work / not working (in this case) to match this last occurring bracket closure)
and
Simpler version of the string (Matchable in any easy way)
I would like to define a str.match() that matches this last part of the strings above. Resulting in:
Work / not working (in this case) to match this last occurring bracket closure
and
Matchable in any easy way
Any good way to achieve this? Sadly the data is highly volatile that a strong Regex is much rather preferred instead of long functional logic. Thanks so much!
So far I've been trying to get a simple way to stract a title from an HTML page.
This simple:
$url = "http://localhost";
Use any function to extract the title tag using only PHP functions or regular expressions, I do not want to use any external classes such as simple_html_dom or Zend_Dom... I want to do it the simple way with PHP only... can anyone post a sample code to simply extract the title tag from localhost?
I've tried using DOMdocument() class, simple_xml_parse(), and none of them with success
I tried like this:
<?php $dom = new DOMdocument();
$dom->loadhtml('pag.html');
$items = $dom->getElementsByTagName('title');
foreach ($items as $title) { echo "title"; }
I used to have strings like this:
233.43 USD
634,233 EURO
and I used to extract numbers from those strings using this:
def extractNumbersFromString(value): #This function is to get the numbers froma string
return re.search('(\d+(?:[.,]\d*)*)', value).group(1)
Now I got strings like these as well:
2300 000 USD
430 000 EU
where there is a space between the numbers and the zeros on the right.
How can I adjust my code to extract the numbers from those strings?
Required output:
2300000
430000
My code currently gives me just this 2300 and 430 (i.e. without the zeros on the right).
I have the following string inside the source of some website:
user_count: <b>5.122.512</b>
Is this possible to get the number out of this string, even if the tags around this number were different? I mean, "user_count:" part won't change, but the tags can be changed, to strong for example. Or the tags could be doubled, or whatever.
How can I do that?
I would like only one regular expression to extract the number of days, weeks, months and/or years from the following codes:
AB7YT1M=ABC ==> 7Y1M
AB10YT1M=ABC ==> 10Y1M
AB30YT1M=ABC ==> 30Y1M
ABCDEF1Y1M=A ==> 1Y1M
ABCDEF34Y6M=A ==> 34Y6M
ABCDEF7M=A ==> 7M
ABCDEF1D=A ==> 1D
@"(\d+[DWMY])(?!\w+(1))(\d+[DWMY])(?!\w+(1))|(\d+[DWMY])(?!\w+(1))"
This code does not support e.g. 30YT1M
Could someone please help find an appropriate regexp for me?
Assuming I have these variations:
1: Today is a beautiful day (Monday)
2: Today is a beautiful day
I want to get Today is a beautiful day.
I'm trying preg_match('/(?=(^\w+.+))$|(?=(^\w+.+)\s\())/ui', $string, $matches) without success.
I have a MySQL table with 4 millions of records having a field like "hello@xyz22-03-2015". Concatenated date is not fixed for all 4 million records. I am wondering how can I remove the numbers or any string after @xyz using mysql. One possible solution must be somehow with Regular expression and I know that Mysql does not allow replace using regex, so I am wondering how this particular task can be completed. I want to remove everything after @xyz.com
Many thanks
I want to match config.json and config.staging.json and config.anything.json
So far I have configFile.match /config\.(.*)\.json/i
I am using sahi for automate the website, when I record the actions from the sahi recorder then it record click action of a button(actually "span") as _click(_span("Done[4]"));
but when I play the recorded script then it got failed on that line as it does not found the "Done[4]".
To solve this I just tried Regular expression to click on the _span("Done[4]") but no luck.
HTML Source structure :(this get displayed in popup [ui-dialog,ui-widget])

I tried followings one by one:
_click(_span(/Done.*/));
_click(_span(/Done\\[[0-9]\\]/));
_click(_span(/Done\[[0-9]\]/));
_click(_span(/Done/i));
_click(_span("/Done/"));
_click(_span(new Reg Exp("Done\\[[0-9]\\]")));
_click(_span(/Done.*/,_near(_div("addWidgetDone_wrapper[1]"))));
_click(_span(/Done.*/,_near(_div(/addWidgetDone_wrapper\\[[0-9]\\]/))));
_click(_span(/Done.*/,_near(_div(/addWidgetDone_wrapper.*/))));
_click(_span(/Done.*/,_in(_div("addWidgetDone_wrapper[1]"))));
_click(_span(/Done.*/,_in(_div(/addWidgetDone_wrapper/))));
_click(_span(/Done.*/,_in(_div(/addWidgetDone_wrapper.*/))));
and many more other combination but none of them working.

Can any one please tell me what wrong I am doing?
Note : In recorded action "Done[4]" the numeric part is getting changed every time.
I'm currently trying to validate a time based attribute called duration for one of my models. The attribute, would accept something along the lines of 01:30 as a valid value. The goal is to have a 4 digit time-code (minutes and seconds) with a colon in between the two. Both minutes and seconds limit in range 59 and cannot have 00:00 as a value. The regex I currently have doesn't seem to work:
validates :duration, presence: true, format: {with: /A([0-9]|0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]z/}
I'm new to this web site and hope I'm doing this correctly.
I'm looking for some sort of PHP-code to scan my /var/log/secure to filter breakin attempts. Below are just some examples of string that need to be searched and get the IP address ONLY. I'm using 0.0.0.0 as an example of an IP address and not the actual IP.
Failed password for invalid user admin from 0.0.0.0 port 3108
Invalid user ubnt from 0.0.0.0

I'm trying to build the parameters used in the regex expression in a find command from a shell script but it seems does not work.
Objective of this shell script is to be able to find some files according with specified parameters in shell script.
The shell script looks like something like:
#!/bin/bash
IDS=$1
FOLDER="/tmp"
MODULENAMEPATTERN=`echo $IDS | sed "s/,/|/g"`
MODULENAMEPATTERN=".*\\.\\($MODULENAMEPATTERN\\)"
echo "find command: find $FOLDER -follow -type f -regex \"$MODULENAMEPATTERN.suffix\""
for FILEFOUND in `find $FOLDER -follow -type f -regex "$MODULENAMEPATTERN.suffix"`; do
echo $FILEFOUND
done;
To launch it, I use the following command:
./test pattern1,pattern2
it generate the following output:
find command: /tmp -follow -type f -regex ".*\.\(pattern1\|pattern2\).suffix"
But nothing more.
Unfortunately, if I execute the generated find command from a terminal, it generate the following output:
/tmp/folder1/.pattern1.suffix
/tmp/folder2/.pattern1.suffix
/tmp/folder2/.pattern2.suffix
I do know exactly where is my problem. Can you help me?
Regards
I've got this script:
<input type="text" name="lastnamename" pattern="[^\s]*" title="Delete space before or after sentence!" style="text-transform:uppercase" required>
This pattern "[^\s]*" shows every spaces which has been made in sentence _Adam_Sandler_. I need pattern which shows only _Adam Sandler_ these spaces BEFORE SENTENCE, AND AFTER SENTENCE.
