    ^[^&lt;&gt;]+$

The caret in the character class (`[^`) means match anything but, so this means, beginning of string, then one or more of anything except `&lt;` and `&gt;`, then the end of the string.

Here you go:

    ^[^&lt;&gt;]*$

This will test for string that has no `&lt;` and no `&gt;`

If you want to test for a string that may have `&lt;` and `&gt;`, but must also have something other you should use just

    [^&lt;&gt;] (or ^.*[^&lt;&gt;].*$)

Where `[&lt;&gt;]` means *any of `&lt;` or `&gt;`* and `[^&lt;&gt;]` means *any that is not of `&lt;` or `&gt;`*.

And of course the mandatory [link][1].

I found a blog post on `alias` vs. `alias_method`. As shown in the example given in that blog post, I simply want to alias a method to another within the same class. Which should I use? I always see `alias` used, but someone told me `alias_method` is better.

**Usage of alias**

    class User
    
      def full_name
        puts &quot;Johnnie Walker&quot;
      end
    
      alias name full_name
    end
    
    User.new.name #=&gt;Johnnie Walker

**Usage of alias_method**

    class User
    
      def full_name
        puts &quot;Johnnie Walker&quot;
      end
    
      alias_method :name, :full_name
    end
    
    User.new.name #=&gt;Johnnie Walker

What&#39;s the height of the status bar in Android? Is it always the same?

From my measurements it seems that it&#39;s 25dp, but I&#39;m not sure if it has the same height on all platforms.

(I want to know this to properly implement a fade transition from an activity that doesn&#39;t have status bar to one that does)

I need a regex to match if anywhere in a sentence there is NOT either &lt; or &gt;.

If either &lt; or &gt; are in the string then it must return false.

I had a partial success with this but only if my &lt; &gt; are at the beginning or end:

    (?!&lt;|&gt;).*$

I am using .Net if that makes a difference.

Thanks for the help.

How can I extract a substring from within a string in Ruby?

Example:

    String1 = &quot;&lt;name&gt; &lt;substring&gt;&quot;

I want to extract `substring` from `String1` (i.e. everything within the last occurrence of `&lt;` and `&gt;`).

Extract a substring from a string in Ruby using a regular expression

I need a regex that will only find matches where the entire string matches my query.

For instance if I do a search for movies with the name &quot;Red October&quot; I only want to match on that exact title (case insensitive) but not match titles like &quot;The Hunt For Red October&quot;. Not quite sure I know how to do this. Anyone know?

Thanks!

How do I match an entire string with a regex?

I’ve been trying to get a JavaScript regex command to turn something like `&quot;thisString&quot;` into `&quot;This String&quot;` but the closest I’ve gotten is replacing a letter, resulting in something like `&quot;Thi String&quot;` or `&quot;This tring&quot;`. Any ideas?

To clarify I can handle the simplicity of capitalizing a letter, I’m just not as strong with RegEx, and splitting `&quot;somethingLikeThis&quot;` into `&quot;something Like This&quot;` is where I’m having trouble.

How to convert &quot;camelCase&quot; to &quot;Camel Case&quot;?

I have a problem with the replaceAll for a multiline string:

    String regex = &quot;\\s*/\\*.*\\*/&quot;;
    String testWorks = &quot; /** this should be replaced **/ just text&quot;;
    String testIllegal = &quot; /** this should be replaced \n **/ just text&quot;;
    
    testWorks.replaceAll(regex, &quot;x&quot;); 
    testIllegal.replaceAll(regex, &quot;x&quot;); 

The above works for testWorks, but not for testIllegal!?
Why is that and how can I overcome this? I need to replace something like a comment /* ... */ that spans multiple lines.

I have this string:

but it doesn&#39;t work. How do I do it? Thanks for reading.

I need a single-pass regex for unix grep that contains, say alpha, but does not contain beta.

    grep &#39;alpha&#39; &lt;&gt; | grep -v &#39;beta&#39;

Unix grep regex containing &#39;x&#39; but not containing &#39;y&#39;

I&#39;m trying to write a regular expression to match anything that isn&#39;t &quot;foo&quot; and &quot;bar&quot;.  I found how to match anything but one word at https://stackoverflow.com/questions/406230/regular-expression-to-match-string-not-containing-a-word but I&#39;m not very skilled with regex and am unsure of how to add a second word to this critera.

Any help would be most appreciated! 


CLARIFICATION:

I wanted to match on anything that wasn&#39;t EXACTLY foo or bar.

Regex to match anything but two words

Assume the following strings:

    aaa bbb ccc
    bbb aaa ccc

I want to match `aaa` as long as it is not at the start of the string. I&#39;m trying to negate it by doing something like this:

    [^^]aaa

But I don&#39;t think this is right. Using `preg_replace`.

Regex: match pattern as long as it&#39;s not in the beginning

Below is the content:

    Subject:
        Security ID:        S-1-5-21-3368353891-1012177287-890106238-22451
        Account Name:       ChamaraKer
        Account Domain:     JIC
        Logon ID:       0x1fffb

    Object:
        Object Server:  Security
        Object Type:    File
        Object Name:    D:\ApacheTomcat\apache-tomcat-6.0.36\logs\localhost.2013-07-01.log
        Handle ID:  0x11dc

I need to capture the words after the `Object Name:` word in that line. Which is `D:\ApacheTomcat\apache-tomcat-6.0.36\logs\localhost.2013-07-01.log`.

How can I do this?

`^.*\bObject Name\b.*$` matches - Object Name
