Pattern Matching Accent Insensitive
I am using the Pattern Matcher class in order to do regex matching.
Is there a way to specify accent insensitive matching.
I have a string aeihAEIH������
when searching for ei
I would like to get 4 matches
1) ae
2) AE
3) ��
4) ��
However, I only get 1) & 2)
Here is my code:
Matcher matcher = Pattern.compile("ae", Pattern.CASE_INSENSITIVE | Pattern.UNICODE_CASE).matcher("aeihAEIH������")
Is there a way to accomplish this?

I do not want to explicity specify the accented characters in code.
I want that ae should match also against accented characters of any type unlimited.AFAIK, that is not possible. However, I am a mere grasshopper in the regex-world. If my assumptions are incorrect, I am sure I will be corrected by the regex-lords that roam these forums.

How to apply an accent-insensitive search to an interactive report?
Hello all!
I'm trying to put an accent-insensitive search on an interactive report here. For example, if I'm on the page that has the interactive report and if I click the column header of the interactive report, I get to see a search bar that dynamically shows the results that match your input. Now, when I enter "jager", I want to see *"Jägermeister"* as a search result. The search must be accent-insensitive, so that I don't have to enter the ä every time.
My code is as follows:
SELECT name
FROM food_1
WHERE name LIKE 'Jagerme%'
AND NLSSORT(name) IS NOT NULL
ORDER BY NLSSORT(name, 'NLS_SORT=GENERIC_M_AI');As you can see, I first tried getting a result through the SQL Command. It should return the row that has "Jägermeister" as name. However, it doesn't. It tells me "No data found". So, how do I alter my NLSSORT to search accent-insensitive?
Some extra information, I edited the interactive report source to the following:
SELECT DISTINCT a.name, a.foodid
FROM food_1 a INNER JOIN foodunit_1 c
ON a.foodid = c.foodid
WHERE a.foodlanguageid = :P17_SET_LANGUAGE
AND NLSSORT(a.name) IS NOT NULL
ORDER BY NLSSORT(a.name, 'NLS_SORT=GENERIC_M_AI');I also tried doing ALTER SESSION before the SQL code, but it still gives me the same result: No data found.
I'm using APEX version 4.1.1.00.23.
Help and suggestions are more than welcome. ;)
Thanks in advance,
MagaliI found it out!
It's really ridiculous, actually.
Remember this code?
execute immediate ('ALTER session SET NLS_COMP=LINGUISTIC');
execute immediate ('ALTER session SET NLS_SORT=BINARY_AI');Well, this code is perfectly fine. Only, it doesn't execute. This is because it was misplaced...This process is not executed when you place it in the current authentication scheme, under the "Post-Authenticatoin Process" part.
You might wonder why this is, but I have the explanation to that.
You see, when you use an interactive report, the page processing isn't executed when you use the search function of that interactive report... Because it's an interactive report, I guess.
BUT.
An ALTER SESSION from the security attributes, that will execute.
So, the solution to my problem was, in this case:
Go to "Application" --> "Shared Objects" --> "Security Attributes" --> "Database Session" --> "Initialization PL/SQL code". In there, you need to put:
BEGIN
EXECUTE IMMEDIATE 'ALTER session SET NLS_COMP=LINGUISTIC';
EXECUTE IMMEDIATE 'ALTER session SET NLS_SORT=BINARY_AI';
END;By doing this, there's no longer any need to edit the source code of the report!
So, that's the solution. I can finally enter text without special characters in it, and get the corresponding data, with special characters... Ahh. :)
I hope this is helpful to others as well now. ;) -
How do I set multiple pattern matching Vi's and make overlapping pattern matches to count as one?
Hello! I'm a student and I'm currently making a project using pattern matching.
My patterns are from chick foot/feet.
I'm created multiple pattern matching VI's to detect all the feet because I find it difficult/impossible to match all the feet with a single pattern/template.
However, when using multiple pattern matching VI's some pattern matches detect the same foot, hence overlapping.
So how can I make the overlaping pattern matches to be counted as one?
Thank you in advanceThank you for replying Sir Zwired1.
I'm still a newbie in using LabVIEW so pardon me if I can't understand fully
The objective of my project is to detect all the feet through pattern matching and count the pattern matches made.
"Keep a 2D array of counts, initialized to zero and the same size as your array of possible locations, and increment the value every time you get a match. If multiple pattern matching attempts result in a match a given location in your count array might be "3" but all you care about is if the number is greater than zero."
I'm sorry, but how do you do this? BTW, I'm using vision assistant. -
Trouble using a pattern match in the GO URL when the value starts with %
Hi guys,
We are trying to use a Go URL as follows:
[http://hostname.com:9704/analytics/saw.dll?Go&Path=/users/administrator/Test/TestReport&Action=Navigate&col1=TestReport.SUBJECT&op1=like&val1="%25D8D8%25"|http://hostname.com:9704/analytics/saw.dll?Go&Path=/users/administrator/Test/TestReport&Action=Navigate&col1=TestReport.SUBJECT&op1=like&val1="%25D8D8%25"]
Basically, we want to send the filter : SUBJECT like '%D8D8%' in the GoURL. However, the report that opens up does not fetch any rows because BI somehow messes up the clause by not recognizing the leading %25 (which is an escaped % character). Instead it resolves the %25D8D8%25 into something like �D8% .
As you can see, the %25 at the end however gets resolved correctly but somehow the one at the beginning gets clubbed with the leading D8 to give �.
Any idea, how to get BI to accept a leading escaped % character when doing a pattern match in the Go URL?I'm heading to the Apple Store in Danbury CT tomorrow to test out a MacBook Pro. I'll happily post what I like and dislike here.

Hey all,
I would like to know how can I read a template´s information to know if it is a pattern macthing or a geometric matching template?
In my code, users provide templates and the algorithm must match them using pattern matching or geometric matching depending on the template.
At the moment I am doing it by including a P or a G in the name of the file, but I would like to avoid this and read the information from the file.
Any ideas?
Thanks in advance,
Esteban
Solved!
Go to Solution.Hey Esteban,
you can use the VI "IMAQ Is Vision Info Present 2 VI" to reice the information:

OBIEE 11G : Remove label (is like pattern match) in the prompt
Hi Experts,
I have Gone through this thread Re: OBIEE 11G : Remove label (is like pattern match) in the prompt and applied JS as mentioed but
It works for the first display of the page but its back as soon as you hit the apply button
can be it be removed permanently? Thanks in AdvanceHi Nagen,
You can try the following:
Create a variable prompt with the column vales that you want to match
Create a filter in the analysis criteria tab on the column, set to pick up the variable, and define the IS LIKE here.
It is effectively doing the same task as the standard prompt approach does, but in a round-a-bout way which doesn't include adding any of Oracle's text in. -
What I want to do is , have two images on image displays and the pass them through the same setup as the pattern matching example to get the number of matches , I have attached what I have done and also given the pattern matching example program as well.
Hope to get answers back soon,

Pattern Matching Example.vi 100 KBHi there!
The example used can be adapted for comparing two images, however the algorithm and coding for finding the differences is more specific to your actual problem. In terms of the loading and displaying of the images, this can be done in the same way.
Once you have some sort of algorithm, then you can automate the learning and matching by simply wiring them in order. (in the example, these are put in case structures as they are waiting on response from the front panel)
I hope that this helps,

Accent insensitive LIKE in a stored procedure
Hi!
How is it possible to run a SELECT with accent insensitive LIKE in a stored procedure?
ALTER SESSION SET NLS_COMP=xxx is not allowed in procedure body, so what can be done?
I guess i need the LIKE equivalent of NLSSORT(string, 'NLS_SORT = XDanish_ai').
Is there such a thing?
I need this option per statement, not globally.
I use Oracle 11g.
Regards,
DavidI used this approach:
procedure proc1(
p_1 IN VARCHAR2,
p_out OUT sys_refcursor)
is
m_comp VARCHAR2(80);
m_sort VARCHAR2(80);
begin
select value into m_comp from NLS_SESSION_PARAMETERS where parameter='NLS_COMP';
select value into m_sort from NLS_SESSION_PARAMETERS where parameter='NLS_SORT';
execute immediate 'ALTER SESSION SET NLS_COMP=LINGUISTIC';
execute immediate 'ALTER SESSION SET NLS_SORT=Slovenian_ai'; -- I'm not danish ;)
open p_out for
select * from table_a where name like p_1 order by name;
execute immediate 'ALTER SESSION SET NLS_COMP=' || m_comp;
execute immediate 'ALTER SESSION SET NLS_SORT=' || m_sort;
end;This works, but:
- the NLS affects also ordering, which I don't want
- it does not count 'z' and 'ž' as the same, which was the goal I tried to achieve ... -
Regular Expressions (Pattern/Matcher) --- Help
Hi,
I have an regex i.e. Pattern.compile("([0-9])D([0-9])'?(?:([0-9]+)\")?([NSEW])").{code}
It has to exactly match the input e.g *45D15'34"N*
I need to retrieve the values based on grouping.
Group1 = 45 (degree value)
Group2 = 15 (minutes value)
Group3 = 34 (seconds value) ----> this is a non-capturing group
Group4 = N (directions)
The regex works fine for most of longitude/latitude value but I get a StackOverFlow for some. There is a known bug on this http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5050507
According to the bug report, they have said that are many different regex that can trigger the stack overflow....even though the length of my input is not as long as the one posted on the bug report.
I was wondering if anyone could suggest a different way of writing the regex above to avoid the stack over flow.
Thank you in advanceHi,
I missed the '+' in my original regex Pattern.compile("([0-9]+)D([0-9]+)'?(?:([0-9]+)\")?([NSEW])"){code}.
I have also tried {code} Pattern.compile("(\\d+)D(\\d+)'?(?:(\\d+)\")?([NSEW])");And, the other 2 expressions as suggested by you.
The problem happens when Durham Lat=35D52N Lon=78D47W value is selected from a Jtree(the values are parsed from a xml file to the tree - the xml file has a bout 800 longitude/latitude elements for different cities in the US). It does not happen for other values and If I increment the degree or min by, then the expression works. I am not sure how else i could re-write this exp.
Below is the snippet of the xml file:
<State name="NORTH CAROLINA">
<City name="Asheville AP" Lat="35D26'N" Lon="82D32'W"/>
<City name="Charlotte AP" Lat="35D13'N" Lon="80D56'W"/>

who knows how to output some text once labview detects something I want using pattern matching(Vision assistant)?
The text is something like"Yes, this is a coin"
Thanks!I attached a SubVI which I used to place an overlay next to a Pattern, found by a Pattern Match before:
As you can see, you simply pass the image reference and the Array of Matches to the VI along with the String you want to have as an overlay next to the Match.
I also modified your VI a bit, but didn't test it. I created an Array of clusters, each elment containing the template path along with the respective text.
Please note that this is just a hint!

Pattern Matching and Vision Builder 6.0
Hi,
When I select a ROI from an image to generate a pattern matching, Builder
saves it as a PNG file.
If I open this pattern in other application (Paint Shop Pro 7) to modified
it and save as a PNG file, after I can't open this file as a pattern into
Builder, because it is considered as a not valid PNG file.
I have tested this case in LabView 6.i and this problem doesn't appear.
Any solution? Thanks.When the template is first saved in Vision Builder, pattern matching information is stored in the header of the PNG file. This information lets LabVIEW and Vision Builder know how the template was learned. Paint Shop Pro does not keep this information in the file whenever it is saved so Vision Builder will not recognize it as a valid pattern matching template.

Pattern matching for range of numbers
I am facing problem in using a pattern like [200-300] to match any number in the range 200 and 300 inclusive. I wrote following code:
public class RangeTest {
public static void main(String[] args) {
String pat = "[100-200]";
String input = "100";
// incpat.replace("[", "\\[");
// incpat.replace("]", "\\]");
System.out.println("Pattern" + pat);
Pattern pattern = Pattern.compile(pat);
Matcher matcher = pattern.matcher(input);
if (matcher.matches()) {
System.out.println("EPC Matched:" + input + " and pattern:" +matcher.pattern());
}and tested it for different values of input , it's not working. I tried even giving escape characters for "[" and "]" (commented code). Can i use pattern matching in this case.
Please help me.
