Finding td /td tags with regular expressions

hi
first i thought that would be very easy and i used this expression:
String pattern = "<td.*>.*</td>";
but this didn't worke the way i wont. this expression returns hole body which is in between the first <td> and the last </td> tag t
hat means:
<td id=1>(some other tags and text)</td><td id=2>(some other tags and text)</td>
it retruns the whole string and no the two <td id=1>,</td> sections. now i have searched for a wokearound but i didn't finde an useful exaple
can anybody help me?
blub4ever

It will work as long as there are no linefeeds in the start tag or the content, and there are no TD elements inside other TD elements. The first concern can be adressed by setting the DOTALL flag: String pattern = "(?s)<td.*?>.*?</td>";But if the tags can be nested, you have a problem: regexes don't handle nesting very well. By the way, you might find this site helpful:

Get the string between li tags, with regular expression

I have a unordered list, and I want to store all the strings between the li tags (<li>.?</li>)in an array:
<ul>
<li>This is String One</li>
<li>This is String Two</li>
<li>This is String Three</li>
</ul>
This is what have so far:
<li>(.*?)</li>
but it is not correct, I only want the string without the li tags.
Thanks.

Finding the file name with Regular Expression

Hello All,
I am having some requirment to find the file name for the input provided parameter.
In my program i am having an input parameter for file name. This contains both the file name and file stored location.
Example : C:\Dokumente und Einstellungen\xs234fs\Desktop\TEST_123_44.txt
From the above example string i need to find only the file name that is TEST_123_44.txt by using Regular expression.
Please let me know how to get this.
Thank you ver much in advance.
Thanks,
Feroz.

Hello,
If you have attached an F4 help to the filename input param, in that you can use the FM: GUI_FILE_SAVE_DIALOG.
In this there is a return param FILENAME which contains the name of the file.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_FILE.
      CALL FUNCTION 'GUI_FILE_SAVE_DIALOG'
       EXPORTING
         window_title            = TEXT-001
         default_extension       = p_extens
         default_file_name       = ls_deffile
         initial_directory       = ls_initdet
       IMPORTING
         filename                = ls_filename "This contains the filemame
         path                    = ls_path
         fullpath                = ls_fullpath
         user_action             = ls_usaction.
Else if you have hardcoded the filename in the input field you can use rthe FM: PC_SPLIT_COMPLETE_FILENAME to split the filenames into different components

How to search with regular expression

I make pdx files so that I can search text quickly. But Acrobat doesn't provide a way to search with regular expression. I'm wondering if there is a way that I don't know to search for regular expression in Acrobat Pro 9?

First, Acrobat must "mount" the PDX.
As "Find" does not use the cataloged index, use Shift+Ctrl+F to open the advanced search dialog.
It may be helpful to first enter Acrobat Preferences and for the Search category tick "Always use advanced search options".
Back to the Search dialog - use the drop down menu for "Look In" to pick "Select Index" then, if no PDXs show, click the Add button.
In the Open Index File dialog, browse to the location of the desired PDX and select it.
OK out and use "Return results containing" to pick a "Match ..." requirement or Boolean.
To become familiar with query syntax, for Acrobat, it is good to review Acrobat Help.
http://help.adobe.com/en_US/Acrobat/9.0/Professional/WS58a04a822e3e50102bd615109794195ff-7 c4b.w.html

Url pattern tag and regular expression

I am trying to set up my web.xml in Tomcat 4.1.3 container to go to one page if letters are entered in last part of url or go to another page if numbers are entered in the last part of a url.
For example if here is how the url would be set up where the url will go to either the all numbers location or the non numbers location:
Any number entry for last part of url which could be something like 343
http://127.0.0.1:8080/theapp/pack/weburl/343
Any non number entry for last part of url which could be something like abec
http://127.0.0.1:8080/theapp/pack/weburl/abec
My attempt below is not working because it doesnt seem to take the regular expressions. But if I manually put in letters such as: <url-pattern>/pack/weburl/ab</url-pattern> it would take me to the correct page. How does web.xml work with regular expressions inthe url-pattern tag??
<servlet>
<servlet-name>Number</servlet-name>
<servlet-class>pack.Number</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Number</servlet-name>
<url-pattern>/pack/weburl/\d*</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>NotNumber</servlet-name>
<servlet-class>pack.NotNumber</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>NotNumber</servlet-name>
<url-pattern>/pack/weburl/[A-Za-z]</url-pattern>
</servlet-mapping>

Sorry, this pattern can't take regular expressions.
Referring to the servlet spec section 11.2 which defines these mappings
In the web application deployment descriptor, the following syntax is used to define
mappings:
� A string beginning with a �/� character and ending with a �/*� postfix is used
for path mapping.
� A string beginning with a �*.� prefix is used as an extension mapping.
� A string containing only the �/� character indicates the "default" servlet of the
application. In this case the servlet path is the request URI minus the context
path and the path info is null.
� All other strings are used for exact matches only.As an alternative, I would suggest that you match the request to a filter, and then use some logic based on request.getURI() to determine which resource to forward to from there.

Grouping & Back-references with regular expressions on Replace Text window

I really appreciate the inclusion of the Regular Expressions in the search & replace feature. One thing I am missing is back-references in the replacement expression. For instance, in the unix tools vi or sed, I might do something like this:
s/$firstPart$ $secondPart$ $oldThirdPart$/\2 \1 newThirdPart/g
which would allow me to switch the places of firstPart and secondPart, and totally replace thirdPart. If grouping and back-references are already present in the Replace Text window, how does one correctly invoke them?

Assistance with Regular Expression and Tcl

Assistance with Regular Expression and Tcl
Hello Everyone,
I recently began learning Tcl to develop scripts for automating network switch deployments.
In my script, I want to name the device with a location and the last three octets of the base mac address.
I can get the Base MAC address by :
show version | include Base
Base ethernet MAC Address       : 00:00:00:DB:CE:00
And I can get the last three octets of the MAC address using the following regular expression.
([0-9a-f]{2}[:-]){2}([0-9a-f]{2}$)
But I have not been able to figure out how to call the regular expression in the tcl script.
I have checked several resources but have not been able to figure it out. Suggestions?
Ultimately, I want to set the last three octets to a variable (something like below) and then call the variable when I name the switch.
set mac [exec "sh version | i Base"] (include the regular expression)
ios_config "hostname location$mac"
Thanks for any assistance in advance.
Chris

This worked for me.
Switch_1(tcl)#set result [exec show ver | inc Base]
Base ethernet MAC Address       : 00:1B:D4:F8:B1:80
Switch_1(tcl)#regexp {([0-9A-F:]{8}\r)} $result -> mac

Switch_1(tcl)#puts $mac
F8:B1:80

Problem with Regular Expression

Hi There!!
I have a problem with regular expression. I want to validate that one word and second word are same. For that I have written a regex
Pattern p=Pattern.compile("([a-z][a-zA-Z]*)\\s\1");
Matcher m=p.matcher("nikhil nikhil");
boolean t=m.matches();
if (t)
          System.out.println("There is a match");
     else
          System.out.println("There is no match");
The result I am getting is always "There is no match
Your timely help will be much appreciated.

But this will fail in this case.
Matcher m = p.matcher("Nikhil Nikhil");It is the reason for that *[a-z]*.The OP had [a-z][a-zA-Z]* in his code, so presumably he know what that means and wants that String not to match.

Find text Between tags with a Regular Expression

I am trying to find specif text -- table names - within a
<cfquery> tag in all my cfm files. I am using an extend find
function in Homesite (I think Dreamweaver has the same
functionality). This expression works:
<[Cc][fF][qQ][uU][eE][rR][Yy]
[^>]*>[^>]*(EventName|AttendeeName)[^>]*</[Cc][fF][qQ][uU][eE][rR][Yy]>
for find the text EventName or AttendeeName. However, if
there are other cf tags like <cfif> within the
<cfquery>, then the tag/text is not found.
Can anyone help? It is a useful expression to have if you are
trying to transfer applications developed on a windows machine to
a, say, linux machine, and have table name sensititvity issues with
mySql.

Oops: sorry. Stick a question mark after the asterisks to

being greedy.
Used this:
<[Cc][fF][qQ][uU][eE][rR][Yy].*?(EventName|AttendeeName)[^>].*?</[Cc][fF][qQ][uU][eE][rR][ Yy]>
and got some finds again with multiple queries and some

Can't help you there. Sounds like HS's regex processor is
bung: there's
nothing non-standard or tricky about that regex (which might
cause
compatibility issues; JS vs PERL vs Java, etc).
HS on the whole is bung (IMO). Have you considered using a
text editor
that is... err... *current*? ;-)
No, can you suggest one. Just use HS for years and it does
most of what I want.
What sort of errors is it giving?
Regular expression error No 17. Bad expression format or
internal error.

Have you seen this:

How to find sunstring with regular expression?

How can I find a substring in a string with a regular expression?
Example:
I have a original string "<tr><th>RecordId: </th><td valign=middle>A4711</td></tr>"
Now i want to extract the value "A4711" from this string with a regular expression. Everything except "A4711" is fixed, the id "A4711" itself is dynamic. How is it possible to get the substring "A4711" of the original string with a regular expression?

i wrote a little method with the infos above to get such results:
     * Get all substrings of a string that matches a regular expression.
     * @param original String to inspect.
     * @param regExp Regular expression as search criteria.
     * @return All matches of <i>regExp</i> or null if one input parameter is null.
    public static String[] getSubstrings(String original, String regExp) {
        String[] result = null;
        if (original != null && regExp != null) {
            Pattern pattern = Pattern.compile(regExp);
            Matcher matcher = pattern.matcher(original);
            boolean matchFound = matcher.find();
            Vector matches = new Vector();
            while (matchFound) {
                String match = matcher.group();
                matches.addElement(match);
                matchFound = matcher.find();
            }//next match
            int count = matches.size();
            result = new String[count];
            for (int i = 0; i < count; i++) {
                result[i] = (String) matches.elementAt(i);
            }//next match
        }//else: input unavailable
        return result;
    }//getSubstrings()

Help with regular expression needed

Hi,
Perhaps someone here can help me with my regular expression I'm trying to build in my Java code.
The regular expression that I'm looking to build consists of any non-whitespace character up until it finds one or two <>= symbols and then any character thereafter. So both these Strings would match the expression:
City 1==London
Age>=18
The regular expression that I'm using is as follows:
(\\S+)([><=]){1,2}(.+)However, group 1 always retrieves the first <>= symbol as in "City 1=". How can I make the <>= part greedy so that it retrieves both operator symbols?
Thanks.

Make the first group, the non-spaces, reluctant:
"(\\S+?)([<>=]{1,2})(.+)"

Searching in reverse with regular expressions

I have recently constructed a "Find" dialog for my editor and would like to support the use of regular expressions (for people who know more about them than I do.) I have radio buttons that allow the user to search down (from the current caret position to the end of the document) or up (from the current caret position to the beginning of the document.)
I have it working fine with literal text via String.indexOf() and String.lastIndexOf(), but I'm not sure how to implement an "upwards" search using regular expressions. It seems that java.util.regex only provides for searching from the current caret position downwards. Any suggestions?

two not-very-good-for-big-document suggestions
1) search up by searching down (from the beginning) to the last match before the position searched from
2) when the user asks for a search find all matches, number them and keep the index in the doc where they were found, then look up the largest index less than the carets index
you might try constructing succesively larger strings that end at the current caret position, and matching them one by one. If you're near the bottom, and theres no matches, this is also likely to be sloow..

Looping through files with Regular expressions ?

Hi,
My Question is:
if i have the following Regular Expression,
String regrex = "tree\\s\\w{1,4}.+\\s=\\s(.*;)";
The file in which i am looking for the string has multiple entries, is it
possible to do another regular expression on the captured group (.*;)
which is in the original Regular expression ?
The text that is captured by the RE is of the type "(1,(2,((3,5),4)));" for
each entry, and different entries in the file have slightly different syntax
is it possible to loop through the file and first of all check for the presence
of the original RE in each entry of the file
and then secondly, check for the presence of another RE on the captured group?
[ e.g. to check for something like, if the captured group has a 1 followed by a 3
followed by a 5 followed by a and so on ].
Thanks Very much for any help, i've been struggling with this for a while!!
Much appreciated
The code that i have so far is as follows:
import java.util.*;
import java.util.regex.*;
import java.io.*;
import java.lang.*;
import javax.swing.*;
public class ExpressReg {
public String Edit;
public ExpressReg(String editorEx){
Edit = editorEx; // Edit = JTextArea
String regrex = "tree\\s\\w{1,4}.+\\s=\\s(.*;)";
//String regrex1 = "(.*;)";
Pattern p = Pattern.compile(regrex);
Matcher m = p.matcher(editorEx); // matcher can have more than one argument!
boolean result = m.find();
if(result){
JOptionPane.showMessageDialog(null, "String Present in Editor");
else if(!result){
JOptionPane.showMessageDialog(null, "String Not Present In Editor");

if i have the following Regular Expression,
String regrex = "tree\\s\\w{1,4}.+\\s=\\s(.*;)";
The file in which i am looking for the string has multiple entries, is it
possible to do another regular expression on the captured group (.*;)
which is in the original Regular expression ?Yes, the capturing group is $1 (the only one) referenced in source code as m.group(1).
m.group() will return entire matching.
simply use this way:
String result = m.group(1);
// your stuff: could be another validation
The text that is captured by the RE is of the type "(1,(2,((3,5),4)));" for
each entry, and different entries in the file have slightly different syntax
is it possible to loop through the file and first of all check for the presence
of the original RE in each entry of the file
and then secondly, check for the presence of another RE on the captured group?Again "Yes", no limits!
Don't need to create another Matcher, just use m.reset(anotherSourceString)..loop using the same pattern.
Note: Take care with ".*" because regex nature is "greedy", be more specific, eg.: "\\d" just matches digits (0-9).
Can you give us some sample of "slight difference" ?
