Area Code separate from Phone Number - concatenation

jwb4273 — Fri, 17 Jun 2011 03:59:55 GMT

Hello all,

I am trying to get an expression to do the following:

1) Match regular 10 digit US phone number

2) Match 10 digit US phone number with a 1 or +1 in front (including country code)

3) Recognize a 7 digit number and grab the area code from the previous table cell.

I've been able to piece together several separate regex strings to do certain pieces of this, but I can not figure out how to piece them together completely.

1 and 2 are handled by : \+?(1[\s-.]?)?(($\d{3}$)|(\d{3}))[\s.\-]?\d{3}[\s.\-]?\d{4}

For 3, I've been able to make a regex identify the <td> cells by using

(?:<td>|<td [^<]+?>)[\d\w\s\-]*((?!</td>).)*</td>

and been able to find either the area code or 7 digit number by using

(\d{3}|[\s.\-]?\d{4})

However, I can not make those latter 2 mesh up as necessary.

The sample HTML code for the last case is:

TEXT

</td>

TEXT

</td>

512 <<< Areacode

</td>

111-2222 <<<< 7 digit phone number

</td>

Ideally, the output from all 3 cases would be the complete 10 digit number. (the first 2 are obviously easy, the third it has to concatenate).

Any assistance would be helpful! Thank you!

rewrite wordpress search url

misterb — Wed, 11 May 2011 07:25:14 GMT

Regexp in Java to escape double quotes and special cases.

Misha79 — Fri, 15 Apr 2011 21:39:48 GMT

I have a regex in Java to extract out double-quoted text .

Regex in Java : (\"\"|\"[\\s\\S]*?[^\\\\]\")

Input can be any String - .

But there can be cases where strings are : like

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Monaco}span.s1 {text-decoration: underline}

private Regex command = new Regex(@"(^clone$| clone$| clone |^clone )", RegexOptions.Compiled | RegexOptions.IgnoreCase);

private Regex username = new Regex(@"--username[\s]+([^\s\""]+|\""[^\""]*\"")", RegexOptions.Compiled | RegexOptions.IgnoreCase);

private Regex passwd= new Regex(@"--password[\s]+([^\s\""]+|\""[^\""]*\"")", RegexOptions.Compiled | RegexOptions.IgnoreCase);

private Regex error = new Regex("(?:file '(?<file>.*?)')|(?:Directory '(<file>.*?)')", RegexOptions.IgnoreCase);

Now these are all-valid strings (or can say regexs ) in C# but if i feed these to my Java program ,it doesnt extract out double quotes well because of \"" in all strings.

if i replace it with "" everything is fine.

But i cannt change the input coming from different sources.I want my Java regex to handle this.

I know there can be many such cases to break the code.(if input can be from multiple sources,languages)but atleast i know this one to handle.

So please suggest me the addition to my regex to handle such cases.

Please ignore

REGULAR EXPRESSIOSN IN JAVASCRIPT FOR VALIDATION

visiontechno — Fri, 10 Dec 2010 06:21:33 GMT

Regular Expressions provide a concise and flexible means for matching strings of text, such as particular characters, words, or patterns of characters. Regular expressions are used by many text editors, utilities, and programming languages to search and manipulate text based on patterns. Some of the symbols used in regular expressions are as follows;

1) Vertical Bar (|) – This symbol is used to separate alternatives. Eg: rear|read can match both 'rear' and 'read'.

2) Parenthesis (()) – Defines the scope and precedence of operators. Eg: rea(r|d) can match both 'rear' and 'read'.

3) Quantification Tokens – There are a list of quantification tokens. Like:

a) ? – This denotes that there may be one or zero instance of the symbol present. Eg: rea?d can match both 'read' and 'red'

b) * – This denotes that there may be zero or more instance of the symbol present. Eg: rea*d can match all 'read','red','reaaad','reaad' etc.

c) + – This denotes that there may be one or more instance of the symbol present. Eg: rea+d can match all 'read','reaaaad','reaaad','reaad' etc

These expression are of great use when we are checking for a particular pattern through our program in .Net/Javacript. Like it may be useful in checking for any presence of special characters in a username field. It may also come to use when we are validating a mobile number field against the entry of any alphanumeric value. If we know how to use this feature properly, then the time taken for validating several fields may reduce by ½

Let us now see that how we can validate several instances using Javascript Regular Expressions. Eg:

1) Validate against any blank values:

2) Validate against non – words:

3) Validate against any blank values:

4) Trimming a string – Removing its left and right blank spaces:

5) Validating an Email Address:

6) Validating a File Name:

replace characters(seperators) within quotes

speedster — Thu, 18 Nov 2010 16:15:56 GMT

Hi I am debugging a pear package (File_CSV).

At some point for a line all seperators within quotes need to be replaced with an underscore.

The code that is being used right now:

$orgLine = '1001;"test1";"semicolon ; in this string" ';

$line = preg_replace("|^[^"\';]*;*(["\'][^"\']*["\'])|sm", '_', $orgLine);

It is faulty.

I guess the tricky part is within quotes is valid only if lefthand quote-position= oneven and righthand quote-position=even , otherwise the semicolon is used as a seperator.

Anyone any suggestiones?

URL redirect, probably very simple

marcus33cz — Sun, 04 Jul 2010 16:17:59 GMT

Hiya all,

I know it's probably very simple but I still can't get this redirect rule to work. I have a PHP website that uses links like this:

http://www.its-not-yet-online.com/index.php?pg=./content/faq (which includes the file ./content/faq.php to index.php) or
http://www.its-not-yet-online.com/index.php?pg=./content/article&id=10 (which includes the file ./content/article.php to index.php and sets $_GET['id'] to 10)

And of course I want these links to look nice, so I used .htaccess and this regex:

RewriteRule ^faq$ ./index.php?pg=./content/faq, this works and instead of www.×××.com/faq it shows the address with the pg parameter
RewriteRule ^article-(.+) ./index.php?pg=./content/article&id=$1, this also works

Now to my question, I'd like to make these htaccess rules also "reverse". :-) So when you enter in your browser this:

http://www.its-not-yet-online.com/index.php?pg=./content/faq, it would redirect you to http://www.its-not-yet-online.com/faq using mod_rewrite [R] flag

BUT at the same time the address http://www.its-not-yet-online.com/faq would SHOW the page http://www.its-not-yet-online.com/index.php?pg=./content/faq

So how would you make this:::

RewriteRule ./index.php?pg=./content/some_file some_file [R]
RewriteRule ./index.php?pg=./content/some_file&id=identificator some_file/identificator [R]

The address ./index.php?pg=./content/detail&id=contact would then redirect to ./detail/contact and
the address ./index.php?pg=./content/faq would then redirect to ./detail/faq

I tried to escape all sorts of different characters but I've always failed...

Regular Expression for xml MatchPattern node (Help)

RegexNewbie — Sat, 19 Jun 2010 22:48:37 GMT

Helo everyone,

I am new here and today I had my first expression with Regular Expressions. I read for hours and I am trying but my expression doesnt work. I Have a xml that has the rules for extracting some values from a file to show them to thes users (the program is in VB). The file contains this line -->

Delivery: Phone:989909 Country:Blabla Type1 A 1232 Town:BLKAKAKAKK

Delivery: Phone:898989 Country:Blabla Type2334 B 2223 Town:ujhsuhwuhu jjjhj

Delivery: Phone:122344 Country:Blabla Type3 C 2222 Town:uhuhuh

I need the values (not numeric) A,B,C (len = 3) after the Strings Type1,Type2334,Type3 and before the Town String. The four Strings are Const. So I have created the following Regex for the xml-->

?<=Type1|Type2334|Type3\s+).{1,17}\s*.{1,17}\s*

It works fine but sometimes I get the wrong result. Thats because the length of the String is not allways the same and the spaces are too many... I have no Idea what I can do to solve this problem. I have tried to combine the negative lookahead but it doesnt work -->

<MatchPattern><![CDATA[(?<=Type1|Type2334|Type3\s+).{1,17}\s*.{1,17}\s*(?<!Town\s+)]]></MatchPattern> (I dont remember right now the syntax for a negativ lookahead).

The result was nothing. I need really Help. Please tell me also if there is a way to ignore spaces. Thank you very Much! The XML Code follows -->

<DocFields><ID>DocSeries</ID>

<Optional>false</Optional>

</DocFields>

Replacing characters with RegEx values

Jaxx — Wed, 16 Jun 2010 08:14:55 GMT

Hi!

I have a list of german words like this:

fuß, müßig, fleißig, muss, mäßig

In my program I have to search this list for some words which are in another list. My Problem:

In German language you can write the characters ä, ö, ü and ß also like ae, oe, ue, ss. Now I need to prepare the words in the list like this:

In my program this RegEx will then be parsed and checked against the other list. I already did this replacement with the code in my program (for example: Regex.Replace(words, "(ä|ae)", "(ä|ae)")) but I have to do this character by character. Can anybody tell me the RegEx to replace the all the characters at once?

Best regards

Jaxx

Replace only if match found

meason — Mon, 14 Jun 2010 19:18:25 GMT

Trying to set up a URL replace in IIS 7 so I have one line for a regex and one line for a replace string.

Example strings I'm trying to match

1) /type-style_123_s456.html

2) /type_123.html?s=456

Trying to get it to end up as

/page.aspx?t=123&s=456

I've gotten as far as

^/?[^_/]+_*([0-9]*)(?:_+s([0-9]*))*\.html\?*(.*)$

with the replace string as

/page.aspx?t=$1&s=$2&$3

This works in the first case which creates /page.aspx?t=123&s=456& but in the second case it creates /page.aspx?t=123&s=&s=456. This creates an error because there is now two "s" in the new string.

Can I make the &s= only appear in the new string if it was matched in the original?

The final (.*) is necessary because it needs to grab anything remaining on the querystring.

The full expression also takes more then the two parameters above which I've shown below if that has any bearing on suggestions.

^/?[^_/]+_*([0-9]*)(?:_+m([0-9]*))*(?:_+s([0-9]*))*(?:_+oa([0-9]*)-([0-9]*))*(?:_+ob([0-9]*)-([0-9]*))*\.html\?*(.*)$

/products/default.aspx?tid={R:1}&mfr={R:2}&st={R:3}&o{R:4}={R:5}&o{R:6}={R:7}?{R:8}

Thanks in advance.

search&replace operation - Perl

pmj1989 — Wed, 31 Mar 2010 17:14:38 GMT

Hello!

I am working on a search&replace regex for Mp3tag, a tool managing audio metadata, which as far as I know is based on Perl-engine. I would like it to study the content of a text field and change it according to specified pattern.

THE PATTERN (It's easier to explain with examples)

from -> to

COMPOSER_1 -> COMPOSER_1
COMPOSER_1, COMPOSER_2 -> COMPOSER_1\\COMPOSER_2
COMPOSER_1, co-produced by COMPOSER_2 -> COMPOSER_1\\COMPOSER_2 (co-prod.)
COMPOSER_1, COMPOSER_2, co-produced by COMPOSER_3, COMPOSER_4 -> COMPOSER_1\\COMPOSER_2\\COMPOSER_3 (co-prod.)\\COMPOSER_4 (co-prod.)

The problem is the limitation of the reapeted backrefernce which captures only the last match :/ Any workarounds for that?

Extract text field inside quotation marks

MultiMarine — Thu, 25 Mar 2010 14:25:40 GMT

I use c# and .NET.

I have this text string where i need to extract different fields seperated by one or more spaces.
All fields can be in optional quotation marks.

Here is the line with the fields:

#VER A 365 20080722 "This \"is\" some text" 20090614

I have gotten this far:

#VER A 365 20080722

Using this expression.

^\s*\#VER\s+("?)(?<type>\w+)\1\s+("?)(?<number>\d+)\2\s+("?)(?<date>\d{8})\3\s+

The problem is the text part. This field allow spaces if it's in quotation marks, otherwise spaces are not allowed.
The field also allows quotation marks to be part of the text if it is preceded with a backslash(\").

Text field examples:

"This \"is\" some text" -> This "is" some text
"JustAWord" -> JustAWord
\"JustAWord\" -> "JustAWord"

The text allow all characters except [\x00-\x1F\x7F].
So [^\x00-\x1F\x7F] for text with and [^\x00-\x1F\x7F\s] for text without quotation marks can be used.

How do i extract this text?

Help very much appreciated!

append slash to url (if not a file)

chrisd — Tue, 02 Mar 2010 21:39:00 GMT

Hi,

I've been racking my brain without success (writer's block combined with inexperience?).

I need to append a slash (only) if there isn't already a 3-4 letter extension. I'm using IIS7's url rewrite module.

For example:

http://mydomain.com/mypage becomes http://mydomain.com/mypage/

While http://mydomain.com/mypage1.aspx or http://mydomain.com/mypage/ are left alone.

Anyone have any pointers?
