bracket in the regex constant?

I'm a little perplexed by the behavior I feel in LV 2011. I hope to have light experts out there.

I try to analyze a messy header ASCII file and after you divide it into individual lines (strings), I use the regular "Match phrase" function to remove some of the information prior to the important information.

Strings of hooks (-), which are special characters for the function, that of why, as documented in help, it takes preceded them by a backslash.

Example:

I want to analyze the following line:

#PR [PR_DEV, I, 2]

One way (which I use because of considerations related to the rest of the header) is the following:

Note that the first constant string using 'Display of the Code' while the other is the use of 'Normal view'.

Why did not a backslash in front of the media in the first string, you may ask? Well, I did, but he disappeared after typing the other characters. And returning to "Normal view" did not restore.

Of course, the first version is not parsed the input properly, string while the other does very well.

In other words, the display string custom (which is convenient for the cryptic codes such as \s* or establishing a distinction between space and tab...) (or simply the tabs ENTRY!) seems to mess with the------[combo (even with the-)] a).

It's not a huge deal. I can use the "Normal view" mode, but I tend to think that this is a "hidden" feature And once again, it is always a pain in the... when it comes to special characters like tabs, etc...

I think that [is a special character that must be preceded by a bar backslash, but this isn't one of the characters backslash defined (as \s).] So, you have to put in two-to get a------while in '-' display Codes.

You can put in any character using \xx where xx is a hexagon of characters using only uppercase letters for a... F. I converted the strings in arrays of bytes and tried to see what made the berries game and Match work.

  • If the name of the document matches the regex, read actions

    I am often in a situation where, after completing work on several documents open photoshop, I want to play a specific action on some of them. The name of the file ALWAYS correspond to a model that should be easy enough to match with regex. Essentially:

    If the name of the document is 5 or 6 digits + 'F', read the actions.

    If the name of the document is 5 or 6 figures + "FX", read for the B shares.

    If the name of the document is 5 or 6 digits + 'B', read the actions.

    If the name of the document is 5 or 6 figures + "BX", read for the B shares.

    I believe that this requires a loop for to look through each open doc, then a if docName matches the regex, then play correct action.  But I can't put them all together and would very much help.

    Thank you!

    Hi squirpy,

    You can use a switch box or an if else clause. There is no difference.

    // be sure that action set with name actionSet exists
    // be sure that action1 in action set with name actionSet exists
    for(i=0; i

  • Need help on the use of the Regex to parse the addresses

    Let me start by saying three things:

    1. I suck at the regex
    2. I googled this and did not come with an answer, and
    3. I am in ColdFusion 10

    I have a form with an AutoComplete entry that allows a user to enter street addresses (either in full as "123 Main St, Mayberry" or in the part "123 Main St" or "Main St" or "Main St, Mayberry".)  I need to say if the user provided a street number or not at the beginning of the value they get into the entry.  I'm testing the value of entry with this code:

    < ReFind ("^([0-9]{1-5})", q) cfif >

    <! - address begins with a number - >

    < cfelse >

    <! - address does not start with a number - >

    < / cfelse >

    q is the input value passed in my code for the AutoComplete feature.

    x should be 0 (if the input value does not begin with a number) or a positive integer (if the input value starts with a number).

    Basically, I just need to know if the input value begins with a five-digit.

    I guess I could just do something like:

    < Val (q) cfif >

    I'm better use an expression, and if so, what I'm doing wrong with the one I tried?

    -Carl V.

    1.5 {} {1-5} is not.

    Perhaps read my series of articles about CF regexes to help you get up to speed with them better:

  • Question related to the REGEX functions

    Hello

    I'm working on Oracle 10 g 2.

    I'm working on a column that stores the user name. Let's say that one of the values in this column is "John". I want to extract all records where username is a concatenated string of 'Ankur' followed by some numbers, such as 'Ankur1', 'Ankur2', 'Ankur345' and so on. I don't want to get the records that have values such as "Ankurab1" - i.e. everything that is the concatenation of some characters to my input string.

    I tried to use the REGEX functions to achieve the desired result, but am not able to.

    Can someone help me out here?

    Best,

    It is a means.

  • How to check the RegEx validation

    Hello

    My application needs to users to enter the regex. My question is how I can check the validation of the regular expression that users enter. The RegExp class does not provide any methods to check the regular expression validation.

    Kind regards

    Haibin

    You need to hand roll your own validator, unless someone knows of who is there. Flex does not validate the RegEx.

  • How can I convert the name of the element of the enum constant to the text?

    For a control of the enum or indicator, I can use the 'String []' property with array of Index for the text of the element.

    But for an enum constant, I do not know how, but I've seen a solution a few years ago, but I can't remember it.

    Hoping that there wasn't a business developer who's somehow enough to help me.

    Format string is your friend. You even don't need to set the format string input in this case.

  • Orders series does not work with the string constant

    I have a single serial device, I used.  The device requires no handshake.  Simply send a command to the device and the device responds.  I modified the example labview for simple serial communication and that works when I enter the chain command and click the button to send the command to the device.  But when I tried to put the same example of communication series in a simple state machine where I replace the chain control on the front panel with a string constant on the scheme that the standard equipment does not respond.  Where do I go awry with the constant string and the state machine?

    Thank you

    Control of the working channel is \-codes display, while the constant diagram is in normal display. Once you pass the constant \-codes diagram, you will see that it is in fact "/ 1ZR\\r\\n". Switch to \-codes, re - enter the text you want and see if things improve.

  • Character constants and the color constants

    There are many useful character constants,

    but sometimes (if English is not the mother tongue) is not easy to guess what it looks like on the device

    is there anywhere a document showing the visible result of all character constants, or can I do it by myself?

    even for constant colors - is there a document where you can see how would resemble a color?

    For character constants, you can look at the code published by the Unicode Consortium tables. They have an alphabetical list of all Unicode characters to http://www.unicode.org/charts/charindex.html. Each character links to the appropriate code chart.

    Alternatively, there is a nice searchable data base of characters at http://www.fileformat.info/info/unicode/char/search.htm. Just type the name of the character (without the features of underscore) as it appears in the documentation of the api for the characters.

    A web search for "html color table" shot to the top of http://www.devguru.com/Technologies/html/quickref/color_chart.html, which shows the HTML colors by name.

  • How to set the preprocessor constants

    I have Eclipse 3.5, a.k.a Galileo, build 20100218-1602. I also have the BlackBerry Java plug-in 1.1.2.201004161203 - 16.

    When I go to project-> properties-> BlackBerry project, I see only this:

    Documentation and other posts on this forum, I have reason to believe that I should see several tabs, among which will be a field allowing me to define constants using the preprocessor.

    I am mistaken in my belief? If so, how can I see the missing tabs?

    (And until someone says downgrade to Eclipse 3.4.2 can't do for two reasons: (1) the BlackBerry_JDE_PluginFull_1.1.2.201004161203 - 16.exe 368 MB Installer refuses to install on anything less than Eclipse 3.5.0 and URL of BlackBerry (2) for Eclipse update is broken at the moment, so I don't think that there is a way for users of Eclipse 3.4 to walk on BlackBerry development for the moment.)

  • In square brackets [] as the statement does not?

    Hello

    We have an application which, in c# code automatically creates a query such as this;

    SELECT

    (KTOGR) LIKE [xval].

    (round (sum (12 *-0,001), 1)) AS [being]

    TABLE

    It works fine in SQL Server but not in Oracle.

    The problem seems to be LIKE [xval], where if we instead of writing;

    AS xval

    or

    AS "xval".

    then it works.

    But we would like is not to change the behavior of our c# code, if possible.

    According to the documentation [] Oracle is valid charaters in the select statement, but as it seems when try out us - not in the part 'AS' statement.

    Y at - it a setting or similar in Oracle where it is possible to define that [a] should work in the as part of a select statement?

    / Erik

    SQL Server supports the brackets and quotation marks when you set the name of the column with a space or some other column not standard name form s. Oracle supports only double quotes. There is no parameter in oracle to define, its just the quotes.

  • setUpComplexFindReplace() can't find the regex strings

    I wrote an extension to run multiple find and replace by calling setUpComplexFindReplace() and replaceAll() and so far everything works fine, as long as I'm not looking to match a RegEx string.

    Let's say I'm trying to find the ampersand symbol and convert it to a HTML character entity. If I open the dialog box search / replace DW records the following code and save the query. This query in the dialog works search / replace fines and any independent (with a space before and after) & s loading are.

    <? XML version = "1.0"? >
    < dwquery >
    < queryparams matchcase = 'false' ignorewhitespace = 'false' useregexp = "true" wholeword = "false" / >
    < find >
    "< qtext = qname ' \s & amp; \s" qraw = "true" > < / qtext > "
    < / find >
    "" < replace action = 'replaceText' param1 = ' & amp; nbsp; & amp; amp; & amp; nbsp;" param2 = "" / >
    < / dwquery >

    However, passing the foregoing as a parameter to setUpComplexFindReplace() will not find anything:

    dreamweaver.setUpComplexFindReplace ("< dwquery > < queryparams matchcase ="false"ignorewhitespace =" false" useregexp ="true" wholeword ="false"/ > < find > < qtext = qname" \s & amp; \s"qraw ="true"> < / qtext > < / find > < replace action ="replaceText"param1 =" & amp; nbsp; & amp; amp; & amp; nbsp;") param2 = "" / > < / dwquery > ');
    dw.replaceAll ();

    Is this is a bug in the API and is there any workaround?

    Make sure that escape you all characters of backslash: qname = "\s and \s" inescapable qname = '\\s & \\s '.
