Regular Expressions - Removing a Timestamp?

I have hundreds of plain HTML pages. I'd like to remove the
timestamp from them, which looks like this:
[19:45]
I've tried using the wildcard feature, but the problem is is
that I want the BRACKETS gone, as well. Unfortunately, I've only
succeeded in removing either the last bracket (with the open
bracket and time still intact) or all of my data completely. How
can I successfully delete the varying times and their brackets
without touching the rest of my data?

In Find/Replace, with Use Regular Expression turned on:
Find:
\[\d\d?:\d\d?\]
Replace:
(leave it blank)

Do you want to remove the email address, or to remove the
whole <a>
tag containing same?

Regular expression: remove quotes except where there is a pipe in the middle

input file:
Column1|"Column | 2"|Column 3|Column 4
Column 1|"Column" 2|Column 3|Column 4
require a sed/awk command to end up with
Column1|"Column | 2"|Column 3|Column 4
Column 1|Column 2|Column 3|Column 4
i.e. remove double quotes but only when there's no pipe contained within the quotes.
Any ideas? I need it to be a one liner preferably, as this will go into an 11g external load pre-parser.

Hi - That's right technically, but I guess this is what the OP needs: "remove double quotes but only when there's no pipe contained within the quotes." As per my understanding, it also implies that there could be a double-quote between the pipe symbol. If you see both the sample files of the OP's and yours - marked 1 and 2 there is a double quote that does not need to be removed.
input file:
Column1|"Column | 2"|Column 3|Column 4 -->1
Column 1|"Column" 2|Column 3|Column 4
testfile:
Column1|"Column | 2"|Column 3|Column 4
Column 1|2 "Column 2|Column 3|Column 4 -->2

Regular Expression to remove space in HTML Tag

Hello All,
My HTML string is like below.
select '<CityName>RICHMOND</CityName>
<StateCd>ABCD CDE
<StateCd/>
<CtryCd>CAN</CtryCd>
<CtrySubDivCd>BC</CtrySubDivCd>' Str from dual
Desired Output is
<CityName>RICHMOND</CityName><StateCd>ABCD CDE
<StateCd/><CtryCd>CAN</CtryCd><CtrySubDivCd>BC</CtrySubDivCd>
i.e. want to remove those spaces from tag value area having only spaces otherwise leave as it is. Please help to implement the same using Regular expression.

Hi,
It's unclear what you want. This site seems to be formatting your message in some odd way.
Post a statement like
SELECT '...' FROM dual;
without any formatting, to show your input, and post the exact output you want friom that, with as little formatting as possible. It might help if you use some character like ~ instead of spaces (just for posting; we'll find a solution that works for spaces).
To remove the text that consists of spaces and nothing else between the tags, you can say
REGEXP_REPLACE ( str
, '> +<'
, '><'
How is this string being generated? Maybe there's some easier, more efficient way to keep the bad sub-wrtings out of the string in the first place.

How can I remove all content between two tags using Find/Replace regular expressions?

This one is driving me bonkers... I'm relatively new to regular expressions, but I'm trying to get Dreamweaver to remove all content between two tags in an XML document. For example, let's say I have the following XML:
<custom>
<![CDATA[<p>Some text</p>
<p>Some more text</p>]]>
</custom>
I'd like to do a Find/Replace that produces:
<custom>
</custom>
In essence, I'd like to strip all of the content between two tags. Ideally, I'd like to know how to strip the CDATA content as well, to return the following:
<custom>
<![CDATA[]]>
</custom>
I'd much appreciate any suggestions on accomplishing this.
Many thanks!

Thanks much for your response. I found David's article to be a little thin with respect to examples using quantifiers in coordination with the wildcard metacharacters; however, I was able to cobble together a working expression through trial and error using the information he presented. For posterity, here’s the solution:
Find:
<custom>[\d\D]*?</custom>
Replace:
<custom>
<![CDATA[]]>
</custom>
I believe this literally translates to:
[] = find anything in this range/character class
\d = find any digit character (i.e. any number)
\D = find any non-digit character (i.e. anything except numbers)
*? = match zero or more times, but as few times as possible (i.e. match multiple characters per instance, but only match one instance at a time, or none at all)
I’m still not sure how to effectively utilize the . wildcard. For example, the following expression will not find content that ends with a number:
<custom>.*?[\D]*?</ custom >
I'm presuming this is because numbers aren't included in the \D metacharacter; however, shouldn't numbers be picked up by the .*? expression?

Regular Expression for Removing a space after the a... tag?

Hi there,
I'm fairly new to using Regular Expressions, but am in need of one that will help me find all <a...> tags that have a space immediately following that tag and replace it with the exact same tag, but no space following the <a...> tag.
So, for example, a regular expression that will find:
<a href="somelink.html"> Somelink</a>
as well as:
<a href="#" onmouseout="MM_swapImgRestore()" onmouseover="MM_swapImage('sub-nav_button_professional_portal','','images/sub-nav_button_ professional_portal_f2.png',1)"> Somelink</a>
And just remove the space appearing as part of the hyperlink. Does anyone know how to accomplish this?

Thought of that, but it would remove spaces from crucial areas of my pages. For example, conditional logic within a script, like:
for (i = 0; i > (a.length - 2); i += 3)
would become:
for (i = 0; i >(a.length - 2); i += 3)
While that wouldn't pose a huge problem, I'm messing up the syntax in order to fix something else, which is why I wanted to go the route of a regular expression. I need to replace all "<a ...> " (space included) tags with "<a ...>" and make sure that the properties within the <a> tag stay in tact.

Regular expression to remove SIDs from list

Hey everyone so I have a script and in it I try to find the current user, as well as the last user. Currently I'm using a regular expression to throw the System account SIDs and other things like that out of the list. However this doesn't seem to be taking
SQL SIDs out of my list ie. ReportServer$LOCAL with the SID S-1-5-80-4264962431-3932693095-1576469926-235475122-2208986020
What's the best way to get only user SIDs?
Here's what I have so far:
$Win32User = Get-WmiObject -Class Win32_UserProfile -ComputerName $Computer
$Win32User = $Win32User | Where-Object {($_.SID -notmatch "^S-1-5-\d[18|19|20]$")}
$Win32User = $Win32User | Sort-Object -Property LastUseTime -Descending
$LastUser = $Win32User | Select-Object -First 1
When I can this it breaks since there is no actual user tied to this SID:
$UserSID = New-Object System.Security.Principal.SecurityIdentifier($LastUser.SID)
$User = $UserSID.Translate([System.Security.Principal.NTAccount])
Thanks for any help!!

Start cmd.exe as your domain user and run whoami /user to get your own SID. You will get something like this:
USER INFORMATION
User Name SID
========================= =============================================
DEMOSYSTEM\CustomAccount1 S-1-5-21-3419697060-3810377854-678604692-1000
The last part of the SID, in this case 1000, is called RID. When you create a new user or computer object in your domain, only the RID will be different from your own SID. The RID starts on 1000 and increments as you create new objects.
If you are only interested in user accounts from the same domain as your user, you can use a regex like this, only based on your own SID:
$_.SID -match '^S-1-5-21-3419697060-3810377854-678604692-[\d]{4,10}$'

Bracket in Regular Expression constant?

I am a bit puzzled by the behavior I am experiencing in LV 2011. I hope to get some light from experts out there.
I am trying to parse a messy ASCII header file and after having split it into individual lines (strings), I use the "Match Regular Expression" function to remove some of the info before the substantial information.
Some of the strings include square brackets ([, ]), which are special characters for the function, therefore, as documented in the help, one needs to precede them with a backslash.
Example:
I want to parse the following line:
#PR [PR_DEV,I,2]
One way (which I am using because of considerations related to the rest of the header) is the the following:
Note that the first string constant is using "Code Display" whereas the second one is using "Normal Display".
Why did I not put a backslash in front of the bracket in the first string, you may ask? Well, I did, but it disappeared after I typed the other characters. And reverting to "Normal Display" did not restore it.
Of course, the first version does not parse the input string correctly, whereas the second one does it fine.
In other words, the custom display string (which is convenient for cryptic codes such as \s* or to distinguish between space and tab...or simply ENTER tabs!) seems to mess up with the \[ combo (likewise with the \] one).
It is not a huge deal. I can use the "Normal Display" mode, but I tend to think that this qualifies as a hidden "feature". And again, it is still a pain in the ... when dealing with special characters such as tabs, etc...
Solved!
Go to Solution.

I think that [ is a special character which needs to be preceded by a backslash, but it is not one of the defined backslash characters (like \s). So, you need to put in two \\ to get one \ while in '\' Codes Display.
You can put in any character by using \xx where the xx is a hex character using only upper case letters for A..F. I converted the strings to byte arrays and tried to see what made the arrays match and the Match work.

Unix Log Monitoring regular expression not picking up alerts

Hi,
We are moving our unix monitoring to SCOM 2012 SP1 rollup 4.
What I have got working is indvidual alert logging of Unix Log alerts by exporting the MP and changing the <IndividualAlerts> value to true and removing the suppression xml section then reimporting the MP.
What I am trying to do is use the regular expression to peform the suppression of specific event (such as event codes).
The expression is:
((?i:warning)(?!(.*1222)|(.*1001)))
ie Search the log for "warning" (not case sensitive) then check if events 1222 or 1001 exist if so return no match, if they dont exist then return true.
I use the built in test function in SCOM when creating the rule and the tests come back as expected but when I inject test lines into the unix log, no alerts get generted.
I suspect it could be the syntax not being accepted on the system (its running RedHat 6 )
I have tested this with regex tools and works.
When I try and test it on the server i get:
[root@bld02 ~]# grep ((?i:Warning)(?!(.*1222)|(.*1001))) /var/log/messages
-bash: !: event not found
[root@bld02 ~]# tail /var/log/messages
Nov 13 15:07:26 bld02 root: SCOM Test Warning Event ID 1001 Round 18
Nov 13 15:07:29 bld02 root: SCOM Test Warning Event ID 1000 Round 18
Nov 13 15:07:35 bld02 root: SCOM Test Warning Event ID 1002 Round 18
So I am expecting 2 alerts to be generated.
SCOM tests to show expression working:
Test 1 Matching
Test 2 to exclude
Need some help with this, Thankyou in advance :)

Hello,
Here's an example of modifying the MP to exclude particular events. Firstly, I created a log file rule using the MP template that is fairly inclusive - matching the string Warning (with either a lower or upper case W).
I then exported the MP, and modified the rule. I set the IndividualAlerts = true and removed the AlertSuppression element, so that every matched line will fire a unique alert. You don't have to remove the AlertSuppression, but you should use
Individual alerts so that the exclusion logic doesn't exclude concurrent events that you actually want to match.
Implementing the exclusion logic involves the addition of a System.ExpressionFilter definition in the rule. This will use a conditional evaluation of the //row element of the data item. Here's an example of a dataitem matching an individual row:
<DataItem type="System.Event.Data"time="2013-11-15T10:33:14.8839662-08:00"sourceHealthServiceId="667FF365-70DD-6607-5B66-F9F95253B29F">
<EventOriginId>{86AB962D-2F44-29FD-A909-B99FF6FEB2C5}</EventOriginId>
<PublisherId>{EC7EA4B1-0EA5-7E8E-701F-82FEF3367BC4}</PublisherId>
<PublisherName>WSManEventProvider</PublisherName>
<EventSourceName>WSManEventProvider</EventSourceName>
<Channel>WSManEventProvider</Channel>
<LoggingComputer/>
<EventNumber>0</EventNumber>
<EventCategory>3</EventCategory>
<EventLevel>0</EventLevel>
<UserName/>
<RawDescription>Detected Entry: warning 1002</RawDescription>
<CollectDescription Type="Boolean">true</CollectDescription>
<EventData>
<DataItem type="SCXLogProviderDataSourceData"time="2013-11-15T10:33:14.8839662-08:00"sourceHealthServiceId="667FF365-70DD-6607-5B66-F9F95253B29F">
<SCXLogProviderDataSourceData>
<row>warning 1002</row>
</SCXLogProviderDataSourceData>
</DataItem>
</EventData>
<EventDisplayNumber>0</EventDisplayNumber>
<EventDescription>Detected Entry: warning 1002</EventDescription>
</DataItem>
Here is the rule in the MP XML. The <ConditionDetection>...</ConditionDetection> content was what I added to do the exclusion filtering:
<Rule ID="LogFileTemplate_66b86eaded094c309ffd2631b8367a32.Alert" Enabled="false" Target="Unix!Microsoft.Unix.Computer" ConfirmDelivery="false" Remotable="true" Priority="Normal" DiscardLevel="100">
<Category>EventCollection</Category>
<DataSources>
<DataSource ID="EventDS" TypeID="Unix!Microsoft.Unix.SCXLog.VarPriv.DataSource">
<Host>$Target/Property[Type="Unix!Microsoft.Unix.Computer"]/PrincipalName$</Host>
<LogFile>/tmp/test</LogFile>
<UserName>$RunAs[Name="Unix!Microsoft.Unix.ActionAccount"]/UserName$</UserName>
<Password>$RunAs[Name="Unix!Microsoft.Unix.ActionAccount"]/Password$</Password>
<RegExpFilter>warning</RegExpFilter>
<IndividualAlerts>true</IndividualAlerts>
</DataSource>
</DataSources>
<ConditionDetection TypeID="System!System.ExpressionFilter" ID="Filter">
<Expression>
<RegExExpression>
<ValueExpression>
<XPathQuery Type="String">//row</XPathQuery>
</ValueExpression>
<Operator>DoesNotContainSubstring</Operator>
<Pattern>1001</Pattern>
</RegExExpression>
</Expression>
</ConditionDetection>
<WriteActions>
<WriteAction ID="GenerateAlert" TypeID="Health!System.Health.GenerateAlert">
<Priority>1</Priority>
<Severity>2</Severity>
<AlertName>Log File Alert: ExclusionExample</AlertName>
<AlertDescription>$Data/EventDescription$</AlertDescription>
</WriteAction>
</WriteActions>
</Rule>
I traced this with the Workflow Analyzer as I tested, which shows the logic being applied. Here is the exclusion happening:
Here's more info on the definition of an ExpressionFilter:
http://msdn.microsoft.com/en-us/library/ee692979.aspx
And more information on Regular Expressions in MPs:
http://support.microsoft.com/kb/2702651/en-us
You can also have multiple Expressions in the ExpressionFilter joined by OR or AND operators.
Also, if you are comfortable with the MP authoring, you can just skip the step of creating the rules in the MP template and just author your own MP with the VSAE tool:

Re: [iPlanet-JATO] Re: Use Of models in utility classes - Pease don't forget about the regular expression potential

Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).

Thanks Matt, Mike, Todd
This is a great input for our migration. Though we used the existing
Regular Expression Mapping tool, we did not change this to meet our
own needs as mentioned by Mike.
We would certainly incorporate this to ease our migration.

Great response. By the way, the Regular Expression Tool uses thePerl5 RE
syntax as implemented by Apache OROMatcher. If you're doing lotsof these
sorts of migration changes manually, you should definitely buy theO'Reilly
book "Mastering Regular Expressions" and generate some rules toautomate the
conversion. Although they are definitely confusing at first,regular
expressions are fairly easy to understand with some documentation,and are
superbly effective at tackling this kind of migration task.

Also, (and Matt's document may mention this)
Please bear in mind that this statement is not totally correct:
Since the migration tool does not do much of conversion for
these
utilities we have to do manually.Remember, the iMT is a SUITE of tools. There is the extractiontool, and
the translation tool, and the regular expression tool, and severalother
smaller tools (like the jar and compilation tools). It is correctto state
that the extraction and translation tools only significantlyconvert the
primary ND project objects (the pages, the data objects, and theproject
classes). The extraction and translation tools do minimumtranslation of the
User Module objects (i.e. they repackage the user module classes inthe new
jato module packages). It is correct that for all other utilityclasses
which are not formally part of the ND project, the extraction and
translation tools do not perform any migration.
However, the regular expression tool can "migrate" any arbitrary
file
(utility classes etc) to the degree that the regular expressionrules
correlate to the code present in the arbitrary file. So first andforemost,
if you have alot of spider code in your non-project classes youshould
consider using the regular expression tool and if warranted adding
additional rules to reduce the amount of manual adjustments thatneed to be
made. I can stress this enough. We can even help you write theregular
expression rules if you simply identify the code pattern you wish to
convert. Just because there is not already a regular expressionrule to
match your need does not mean it can't be written. We have notnearly
exhausted the possibilities.
For example if you say, we need to convert
CSpider.getDataObject("X");
To
RequestManager.getRequestContext().getModelManager().getModel(XModel.class);
Maybe we or somebody else in the list can help write that regularexpression if it has not already been written. For instance in thelast
updated spider2jato.xml file there is already aCSpider.getCommonPage("X")
rule:

<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>

Following this example a getDataObject to getModel would look
like this:
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getModel($1Model.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
In fact, one migration developer already wrote that rule andsubmitted it
for inclusion in the basic set. I will post another upgrade to thebasic
regular expression rule set, look for a "file uploaded" posting.Also,
please consider contributing any additional generic rules that youhave
written for inclusion in the basic set.
Please not, that in some cases (Utility classes in particular)
the rule
application may be more effective as TWO sequention rules ratherthan one
monolithic rule. Again using the example above, it will convert
CSpider.getDataObject("Foo");
To
getModel(FooModel.class);
Now that is the most effective conversion for that code if that
code is in
a page or data object class file. But if that code is in a Utilityclass you
really want:
>
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
So to go from
getModel(FooModel.class);
To
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
You would apply a second rule AND you would ONLY run this rule
against
your utility classes so that you would not otherwise affect yourViewBean
and Model classes which are completely fine with the simplegetModel call.
<mapping-rule>
<mapping-rule-primarymatch>

<![CDATA[getModel\(]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getRequestContext().getModelManager().getModel(]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
A similer rule can be applied to getSession and other CSpider APIcalls.
For instance here is the rule for converting getSession calls toleverage
the RequestManager.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getSession\($\.]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getSession\.]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getSession().]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>

Subject: RE: [iPlanet-JATO] Use Of models in utility classes
Namburi,
I will post a document to the group site this evening which has
the
details
on various tactics of migrating these type of utilities.
Essentially,
you
either need to convert these utilities to Models themselves or
keep the
utilities as is and simply use the
RequestManager.getRequestContext.getModelManager().getModel()
to statically access Models.
For CSpSelect.executeImmediate() I have an example of customhelper
method
as a replacement whicch uses JDBC results instead of
CSpDBResult.

Subject: [iPlanet-JATO] Use Of models in utility classes
Hi All,
In the present ND project we have lots of utility classes.
These
classes in diffrent directory. Not part of nd pages.
In these classes we access the dataobjects and do themanipulations.
So we access dataobjects directly like
CSpider.getDataObject("do....");
and then execute it.
Since the migration tool does not do much of conversion forthese
utilities we have to do manually.
My question is Can we access the the models in the postmigration
sameway or do we need requestContext?
We have lots of utility classes which are DataObjectintensive. Can
someone suggest a better way to migrate this kind of code.
Thanks
Namburi
