Search for a regular expression in a 1D array?

I've got a 1D array of strings, and I want to find the row with "Date: yy/mm/dd" in it. Since yy/mm/dd would not necessarily be the same between runs, I can't look for the row with "Date: yy/mm/dd".
I tried using the Search 1D Array with "Date: " and "Date: *" as my element input, but it didn't find either of 'em.
I don't know where in vi.lib the function would be in, otherwise I'd attempt to mod the function to take regular expressions, and my off-the-cuff search attempt (looping through the array & using Match Regular Expression) had some odd errors and still didn't find the row.
Thanks!

What do you define as a "row"? Is each row a single array element? Since your array elements are strings, each array element itself could be a multiline|multirow string itself that might need to be analyzed one row at a time.
To look for patterns:
If you have LabVIEW 8.0 or higher, you can use "Match regular expression". Else you can use "Match Pattern". It really depends how specific you need to be. Are there lines that start with "Date:" but don't contain a formatted date afterwards?
To search for array elements starting with simple string "Date:", use "match first string".

Looking for a regular expression that doesnt take in account java comments

Does somebody knows the valid Regular Expression to match 'cat', but none of this:
//cat
// cat
// cat
//   cat
// something catI've tried with some patterns without success:
[^/][^/](\\s)*cat
(?<!//)catI want to use this, for example, to search java code to detect uses of "System.out" not commented.
thanks

The direct approach--finding the text first and then figuring out whether it's a valid match--won't work. Java supports two other kinds of comment plus string literals, any of which could contain the text you're looking for. Also, comments can contain literals, string literals can contain things that look like comments, even char literals can contain quotation marks. The only way to be sure you're getting valid matches is to actively search for comments and literals so you can ignore them. Pattern p = Pattern.compile(
    "//.*+|"                            // inline comment, or
+ "/\\*(?:[^*]++|\\*(?!/))*+\\*/|"    // multiline or javadoc comment, or
+ "\"(?:[^\"\\\\]++|(?:\\\\.))*+\"|" // string literal, or
+ "\'(?:[^\'\\\\]++|(?:\\\\.))*+\'|" // char literal, or
+ "(System\\.out)"                    // bingo
Matcher m = p.matcher(str);
while (m.find())
if (m.start(1) != -1)
    // bingo
}

Inline display of error message for a regular expression validation

Hi All,
I am using ApexLib in my application.
I am using regular expression validation for some of the items.
Those validation will happen when the button is pressed and the message will be displayed as per the error.
But, I want the errors to be displayed immediately when the focus is away from that item.
as we do for required items.
could anybody help me to achieve it?
Thanks in advance
bye
Srikavi

Hi Srikavi,
to achieve a Validation of an item when leaving the field you'll have to use some javascript code (as ApexLib does internally).
What do you need:
- onChange - Event on your Item
- some Javascript code which is called in the onChange Event (you can put this code either in your page html header or, if it is used more often in your application, in a seperate js File)
- call the ApexLib method apexlib.error.showError to display your error
I actually never tried it myself, but i'm pretty sure that this will work (according to what i've seen in the ApexLib code).
Have fun and tell us how it went,
Peter

Searching for a list of elements in an array

Hi,
In labview you can search an array for an element and it will return
the index of the element that is found. Is it possible to search an
array for a list of elements, say multiple elements that are follow
each other.
For example if I have some array that looks like this
1
0
1
1
1
0
1
1
1
the array continues for about 3000 more elements. This is digital data
thas has been slightly parsed from a pxi 6561. I would like to further
parsing in array form since it would be more efficient than using
strings, (less memory intensive). Is it possible to search in this
array for the sequence 101, and return the index where this is found.
A sample of the array I am referring to is in the indicator of the vi I have attached.
Thank you,
-Tim

Regular Expressions - Logical AND

I know this isn't Java, and it's not really an algorithm, but I can't figure this out. I hope amongst this bright group of developers someone can help me.
I am searching for a regular expressions that will match a series of words.
Example:
Given the words: "ship book"
What regular expression could be used to find both the word "ship" and the "book"?
I have found one expression that will do it ... ship.*book|book.*ship
But that expression doesn't scale. Does anyone know of a better way?
Thanks,
BacMan

Hi,
How about something like:
public class Regexp1
   private static final Pattern all = Pattern.compile(
         "^(\\s*\\b(monkey|turnip|ship|book)\\b\\s*)*$" );
   private static final Pattern p = Pattern.compile(
         "\\s*\\b(monkey|turnip|ship|book)\\b\\s*" );
   public static void main( String[] argv )
      find( "ship book turnip monkey" );
      find( "monkey giraffe mango" );
      find( "ship shipship ship" );
   public static void find( String text )
      System.out.println( "Text: " + text );
      Matcher m = p.matcher( text );
      System.out.println( "Matches all: " + all.matcher( text ).matches() );
      while ( m.find() )
         System.out.println( "Matching word: '" + m.group(1) + "'" );
   }which will produce this when run:
Text: ship book turnip monkey
Matches all: true
Matching word: 'ship'
Matching word: 'book'
Matching word: 'turnip'
Matching word: 'monkey'
Text: monkey giraffe mango
Matches all: false
Matching word: 'monkey'
Text: ship shipship ship
Matches all: false
Matching word: 'ship'
Matching word: 'ship'Pattern all tests to see if all the words are present.
Pattern p finds each matching word and ignores others.

How to Search for "(" error in a string?

I am trying to search for "(" in a string, however the compiler thinks that I searching for a regular expression, and fails.
Exception in thread "main" java.util.regex.PatternSyntaxException: Unclosed group near index 1
Please help me find a way to search for "(" in a string.
Example:
String test="This is a test.";
if (test.matches("(")){
System.out.println("There is a match")
I also tried:
test.matches("\050")
and test.matches("\(")
Thank you!

I also tried:
test.matches("\050")
and test.matches("\(")For this particular problem, I think indexOf is a more appropriate solution. However, for future reference, I think what you want to do for parentheses is escape the backslash, not the bracket.
i.e.
test.matches("\\(");

Regular expression in oracle for hypen

Hi,
I want to match a word "{color:#993300}83-ASG{color}" using regexp_like and i used '{color:#993300}^83-*{color}' pattern to match this word but this also matches words like "{color:#993300}8307-YUF{color}". could anyone please tell me what pattern should i use to match words like {color:#993300}83-ASG{color}.
Also i need to know the similar pattern in oracle for the "{color:#993300}\b{}{color}" used in .net.
Thanks in advance.
Prasad

Hi Prasad,
Your regex could be as simple as '^83-'
So, not much use for a regular expression:
SQL> with test_data as (select '83-ASG' txt from dual union all
                   select '8307-YUF' from dual)
-- end of test data
select txt from test_data
where txt like '83-%'
TXT
83-ASG
1 row selected.Unless, you add some more value to it, perhaps like
SQL> with test_data as (select '83-ASG' txt from dual union all
                   select '8307-YUF' from dual)
-- end of test data
select txt from test_data
where regexp_like(txt, '^83-[[:upper:]]{3}$')
TXT
83-ASG
1 row selected.Regards
Peter

Please recommend a good tutorial for Regular expressions?

I have several PERL programs that I need to translate in to JAVA for performance reasons. Those programs heavily use Regular Expressions. I have an excellent knowledge about PERL Regular Expressions but know very little about Java Regular Expressions.
So Can any one of you recommend me a good tutorial for Java Regular Expressions.
Thankx In Advance

Since you know regexs, the java.util.regex.Pattern class API is probably all you need, it pretty thoroughly documents Java's flavor, and the differences from PERL's flavor.

Regular expression for period plus double line

Hi guys,
i am new to Regular Expressions. How do I construct one to find a period followed by two end of lines.
Also is there a good GUI utility for building regular expressions.
thanks

http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
use
boolean b = Pattern.matches(Regex, Your String);
where
Regex = ".*\\.--.*"
. = anything
* = 0 or more times
You need .* before and after so it will find the pattern inside of
whatever other stuff exists in the string.
You have to escape the period with \\.
(otherwise the . means 'anything' as stated before)
import java.util.regex.Pattern;
public class RegEx{
public static void main(String[] args) {
     String Line = "k1*&.--jh3";
     String RegEx = ".*\\.--.*";
     boolean found = Pattern.matches(RegEx, Line);
     System.out.println("Found? - " + found);
}

If there is any "open source" for parsering regular expressions.
Please send me I am very new to parser technologies.Note that that Pattern class take care of all the parsing of REs, i.e. there's
nothing 'interesting' left for you to do any parsing whatsoever. Can you
elaborate a bit on what you exactly want to do and learn?

Regular expressions in Format Definition add-on

Hello experts,
I have a question about regular expressions. I am a newbie in regular expressions and I could use some help on this one. I tried some 6 hours, but I can't get solve it myself.
Summary of my problem:
In SAP Business One (patch level 42) it is possible to use bank statement processing. A file (full of regular expressions) is to be selected, so it can match certain criteria to the bank statement file. The bank statement file consists of a certain pattern (look at the attached code snippet).

- I am in search of the right type of regular expression that is used by the Format Definition add-on (javascript, .NET, perl, JAVA, python, etc.)
Besides that I need the regular expressions below, so the Format Definition will match the right lines from my bankfile.
- a regular expression that selects lines starting with :61: and line :86: including next lines (if available), so in fact it has to select everything from :86: till :61: again.
- a regular expression that selects the bank account number (position 5-14) from lines starting with :86:
- a regular expression that selects all other info from lines starting with :86: (and following if any), so all positions that follow after the bank account number
I am looking forward to the right solutions, I can give more info if you need any.

Hello Hendri,
Q1:I am in search of the right type of regular expression that is used by the Format Definition add-on (javascript, .NET, perl, JAVA, pythonetc.)
Answer: Format Definition uses .Net regular expression.
You may refer the following examples. If necessary, I can send you a guide about how to use regular expression in Format Defnition. Thanks.
Example 6
Description:
To match a field with an optional field in front. For example, u201C:61:0711211121C216,08N051NONREFu201D or u201C:61:071121C216,08N051NONREFu201D, which comprises of a record identification u201C:61:u201D, a date in the form of YYMMDD, anther optional date MMDD, one or two characters to signify the direction of money flow, a numeric amount value and some other information. The target to be matched is the numeric amount value.
Regular expression:
(?<=:61:\d(\d)?[a-zA-Z]{1,2})((\d(,\d*)?)|(,\d))
Text:
:61:0711211121C216,08N051NONREF
Matches:
1
Tips:
1.     All the fields in front of the target field are described in the look behind assertion embraced by (?<= and ). Especially, the optional field is embraced by parentheses and then a u201C?u201D (question mark). The sub expression for amount is copied from example 1. You can compose your own regular expression for such cases in the form of (?<=REGEX_FOR_FIELDS_IN_FRONT)(REGEX_FOR_TARGET_FIELD), in which REGEX_FOR_FIELDS_IN_FRONT and REGEX_FOR_TARGET_FIELD are respectively the regular expression for the fields in front and the target field. Keep the parentheses therein.
Example 7
Description:
Find all numbers in the free text description, which are possibly document identifications, e.g. for invoices
Regular expression:
(?<=\b)(?<!\.)\d+(?=\b)(?!\.)
Text:
:86:GIRO 6890316
ENERGETICA NATURA BENELU
AFRIKAWEG 14
HULST
3187-A1176
TRANSACTIEDATUM* 03-07-2007
Matches:
6
Tips:
1.     The regular expression given finds all digits between word boundaries except those with a prior dot or following dot; u201C.u201D (dot) is escaped as \.
2.     It may find out some inaccurate matches, like the date in text. If you want to exclude u201C-u201D (hyphen) as prior or following character, resemble the case for u201C.u201D (dot), the regular expression becomes (?<=\b)(?<!\.)(?<!-)\d+(?=\b)(?!\.)(?!-). The matches will be:
:86:GIRO 6890316
ENERGETICA NATURA BENELU
AFRIKAWEG 14
HULST
3187-A1176
TRANSACTIEDATUM* 03-07-2007
You may lose some real values like u201C3187u201D before the u201C-u201D.
Example 8
Description:
Find BP account number in 9 digits with a prior u201CPu201D or u201C0u201D in the first position of free text description
Regular expression:
(?<=^(P|0))\d
Text:
0000006681 FORTIS ASR BETALINGSCENTRUM BV
Matches:
1
Tips:
1.     Use positive look behind assertion (?<=PRIOR_KEYWORD) to express the prior keyword.
2.     u201C^u201D stands for that match starts from the beginning of the text. If the text includes the record identification, you may include it also in the look behind assertion. For example,
:86:0000006681 FORTIS ASR BETALINGSCENTRUM BV
The regular expression becomes
(?<=:86:(P|0))\d
Example 9
Description:
Following example 8, to find the possible BP name after BP account number, which is composed of letter, dot or space.
Regular expression:
(?<=^(P|0)\d)[a-zA-Z. ]*
Text:
0000006681 FORTIS ASR BETALINGSCENTRUM BV
Matches:
1
Tips:
1.     In this case, put BP account number regular expression into the look behind assertion.
Example 10
Description:
Find the possible document identifications in a sub-record of :86: record. Sub-record is like u201C?00u201D, u201C?10u201D etc. A possible document identification sub-record is made up of the following parts:
u2022     keyword u201CREu201D, u201CRGu201D, u201CRu201D, u201CINVu201D, u201CNRu201D, u201CNOu201D, u201CRECHNu201D or u201CRECHNUNGu201D, and
u2022     an optional group made up of following:
     a separator of either a dot, hyphen or slash, and
     an optional space, and
     an optional string starting with keyword u201CNRu201D or u201CNOu201D followed by a separator of either a dot, hyphen or slash, and
     an optional space
u2022     and finally document identification in digits
Regular expression:
(?<=\?\d(RE|RG|R|INV|NR|NO|RECHN|RECHNUNG)((\.|-|/)\s?((NR|NO)(\.|-|/))?\s?)?)\d+

Regular Expressions with Call Policy on VCSe

Hi Guys,
I am working on firming up the call policy on my VCS Expressway to try to better intercept the SIP spam requests it is getting from internet ip numbers. Right now those spam requets are getting rejected by the loop detection but I want to intercept them before they even do a search on the Expressway. It seems that the call policy rules I create without regular expressions are functioning fine but I don't think I have the syntax correct for the regular expressions.
The goal of this rule is to reject any incoming SIP request that has a destination alias format of 7 to 17 digits followed by an @VCSe_IP. so for example it would reject the following attempts: 0123456@VCSe_IP and 0123456789101112@VCSe_IP with one rule.
The policy I created is this: source pattern: unauthenticated user, Destination pattern: \d{7,17}@xx\.xx\.xx\.xx (where xx is the individual octets of the VCSe IP address), Action: reject
However the above policy does not seem to be rejecting the calls before they do a search. I have checked the above expression with the check pattern tool on the VCSe and it comes up with a sucessful match when I try the destination alias of a request that made it through, hence my confusion. Any help you guys could provide would be appreciated.
Thanks,
Steven

Steven,
Default Zone access rules do not relate to this at all and you can keep those set to 'No'.
How exactly are you placing the test calls when attempting to verify this?
I created the following CPL rule on my X7 VCS (With 10.10.10.10 being the IP address of my VCS):
Source pattern:
Destination pattern: \d{7,17}@10\.10\.10\.10
Action: Reject
I then proceeded with placing a SIP call from an unregistered C20, calling the URI '[email protected]' while running a diagnostics log on my VCS with Network log level set to 'DEBUG', and captured the following in that log:

As you can see, on my VCS everything seems to work as expected. I'd recommend you capture a similar diagnostics log on your own VCS to check what is different in your test call compared to the output above.
