I&#39;m trying to implement a &lt;code&gt;SlidingDrawer&lt;/code&gt; that will occupy the full screen width, but whose height is determined dynamically by its contents: in other words, standard &lt;code&gt;fill_parent&lt;/code&gt; layout behaviour for the width and &lt;code&gt;wrap_content&lt;/code&gt; for the height. That&#39;s exactly how I&#39;ve specified it in the layout XML (see below) but the sliding drawer always opens to the full screen height. The height of my content varies, but typically it&#39;s only about half the screen height, so I end up with a big gap underneath it. What I&#39;d like is for the content to sit neatly on the bottom of the screen.

I&#39;ve tried everything I can think of to fix it but nothing&#39;s worked so far. If I set the &lt;code&gt;SlidingDrawer&lt;/code&gt;&#39;s &lt;code&gt;layout_height&lt;/code&gt; to a specific value (e.g. &lt;code&gt;160dip&lt;/code&gt;) it works, but that&#39;s not what I need: it has to be dynamic. Of course I&#39;ve made sure all the child elements have their height set to &lt;code&gt;wrap_content&lt;/code&gt; too.

The documentation on SlidingDrawer is a bit vague on this and I haven&#39;t been able to find any examples that do what I&#39;m after either. If anyone can see where I&#39;m going wrong I&#39;d really appreciate your help!

Android: can height of SlidingDrawer be set with wrap_content?

I have a strongly typed list of custom objects, `MyObject`, which has a property `Id`, along with some other properties.

Let&#39;s say that the `Id` of a `MyObject` defines it as unique and I want to check if my collection doesn&#39;t already have a `MyObject` object that has an `Id` of 1 before I add my new `MyObject` to the collection.

I want to use `if(!List&lt;MyObject&gt;.Contains(myObj))`, but how do I enforce the fact that only one or two properties of `MyObject` define it as unique?

I can use `IComparable`? Or do I only have to override an `Equals` method? If so, I&#39;d need to inherit something first, is that right?

What does Collection.Contains() use to check for existing objects?

Some elements in my array are empty strings based on what the user has submitted. I need to remove those elements. I have this:

    foreach($linksArray as $link)
    {
        if($link == &#39;&#39;)
        {
            unset($link);
        }
    }
    print_r($linksArray);

But it doesn&#39;t work. `$linksArray` still has empty elements. I have also tried doing it with the `empty()` function, but the outcome is the same.

I&#39;ve been developing in PHP for about 8 years as a hobby. In 2009, I picked up codeigniter and since then I&#39;ve not managed to get a single project developed.

I find it slows me down trying to work out how to modify it to work the way I want, when if I was working in pure PHP, I&#39;d know, or I&#39;d be able to quickly find a snippet for.

I&#39;ve tried CodeIgniter, Kohana and Symfony. I love the ease of use (and I&#39;ve also started using doctrine as an ORM which massively sped up my database work), but I find projects are taking me 3-4 times the amount of time it took in pure PHP. I get bored and frustrated when I can&#39;t find a solution to a problem I&#39;ve previously solved in pure PHP.

Has anyone gone back from using frameworks to a no-framework approach. Is there anything like a basic security framework (prevent XSS, filter posted data, provide a cleaning function for use with databases)? I think something like that would benefit me much more than a full scale framework. I think learning to work with frameworks has taught me a lot, but I&#39;d be happier working with my own code.

    // When the above is set, the code that is here will execute of course
    
    }

is being executed for me. When I enter the correct username and password, the prompt box for the authorization again pops up. Wouldn&#39;t both fields be &#39;set&#39; if they are correct and I press enter? But for some reason that is not the case. What can I be doing wrong?
Thank you.

I&#39;m running Mac OS so I can&#39;t really tell if this effect is presented on windows machines or not, so I apologize if this effect is not seen for you.

Input and TextFields seem to have a blue rectangle when focused, atleast on Firefox and Chrome on a Mac.  I have a custom focus effect on a site, and I&#39;m wondering if I can avoid having this default selection behavior show.  Google avoids it on their site.  I went as far as to get the &#39;in-effect&#39; CSS style for Google&#39;s input box, apply that to my css object.  However, it still shows the blue rectangle.  I&#39;m not exactly sure what kind of voodoo google is doing, but it seems to me that it&#39;s neither HTML or CSS attributes.  Anyone know how to avoid this effect?  Thanks!

I am building a website which I am publishing with `div`s. When I refresh the page after it was scrolled to position X, then the page is loaded with the scroll position as X.

How can I force the page to be scrolled to the top on page refresh?

* What I can think of is of some JS or jQuery run as `onLoad()` function of the page to **SET** the pages scroll to top. But I don&#39;t know how I could do that.

* A better option would be if there is some property or something to have the page loaded with its scroll position as default (i.e. at the top) which will be kind of like *page load*, instead of *page refresh*.

I am trying to match a multi line text using java. When I use the `Pattern` class with the `Pattern.MULTILINE` modifier, I am able to match, but I am not able to do so with `(?m).`

The same pattern with `(?m)` and using `String.matches` does not seem to work.

I am sure I am missing something, but no idea what. Am not very good at regular expressions.

This is what I tried

    String test = &quot;User Comments: This is \t a\ta \n test \n\n message \n&quot;;
    		
    String pattern1 = &quot;User Comments: (\\W)*(\\S)*&quot;;
    Pattern p = Pattern.compile(pattern1, Pattern.MULTILINE);
    System.out.println(p.matcher(test).find());  //true
    
    String pattern2 = &quot;(?m)User Comments: (\\W)*(\\S)*&quot;;
    System.out.println(test.matches(pattern2));  //false - why?

Tags can have multiple attributes. The order in which attributes appear in the code does not matter. For example:

How can I &quot;normalize&quot; the HTML in Javascript, so the order of the attributes is always the same? I don&#39;t care which order is chosen, as long as it is always the same. 

**UPDATE**: my original goal was to make it easier to diff (in JavaScript)  2 HTML pages with slight differences. Because users could use different software to edit the code, the order of the attributes could change. This make the diff too verbose.

**ANSWER**: Well, first thanks for all the answers. And YES, it is possible. Here is how I&#39;ve managed to do it. This is a proof of concept, it can certainly be optimized:


    function sort_attributes(a, b) {
      if( a.name == b.name) {
        return 0;
      }

      return (a.name &lt; b.name) ? -1 : 1;
    }

    $(&quot;#original&quot;).find(&#39;*&#39;).each(function() {
      if (this.attributes.length &gt; 1) {
        var attributes = this.attributes;
        var list = [];
        
        for(var i =0; i &lt; attributes.length; i++) {
          list.push(attributes[i]);
        }
    
        list.sort(sort_attributes);
     
        for(var i = 0; i &lt; list.length; i++) {
          this.removeAttribute(list[i].name, list[i].value);
        }

        for(var i = 0; i &lt; list.length; i++) {
          this.setAttribute(list[i].name, list[i].value);
        }
      }
    });

Same thing for the second element of the diff, `$(&#39;#different&#39;)`. Now `$(&#39;#original&#39;).html()` and `$(&#39;#different&#39;).html()` show HTML code with attributes in the same order.

How to normalize HTML in JavaScript or jQuery?

Given a news article webpage (from any major news source such as times or bloomberg), I want to  identify the main article content on that page and throw out the other misc elements such as ads, menus, sidebars, user comments. 

What&#39;s a generic way of doing this that will work on most major news sites?  

What are some good tools or libraries for data mining? (preferably python based)



Web scraping - how to identify main content on a webpage

What is the current state of libraries for scraping websites with Haskell?

I&#39;m trying to make myself do more of my quick oneoff tasks in Haskell, in order to help increase my comfort level with the language. 

In Python, I tend to use the excellent [PyQuery][1] library for this.  Is there something similarly simple and easy in Haskell?  I&#39;ve looked into Tag Soup, and while the parser itself seems nice, actually traversing pages doesn&#39;t seem as nice as it is in other languages.

Is there a better option out there?

How can I strip the HTML from a string in JavaScript?

How to strip HTML tags from string in JavaScript?

I have a file that looks something like this:

``` xml
    &lt;table name=&quot;content_analyzer&quot; primary-key=&quot;id&quot;&gt;
      &lt;type=&quot;global&quot; /&gt;
    &lt;/table&gt;
    &lt;table name=&quot;content_analyzer2&quot; primary-key=&quot;id&quot;&gt;
      &lt;type=&quot;global&quot; /&gt;
    &lt;/table&gt;
    &lt;table name=&quot;content_analyzer_items&quot; primary-key=&quot;id&quot;&gt;
      &lt;type=&quot;global&quot; /&gt;
    &lt;/table&gt;
```

I need to extract anything within the quotes that follow `name=`, i.e., `content_analyzer`, `content_analyzer2` and `content_analyzer_items`.

I am doing this on a Linux box, so a solution using sed, perl, grep or bash is fine.
