I want to know how to simply publish over http = much like [Mercurial][1]&#39;s hg serve! On the Windows/work box do this:

    git serve 

and then on the Linux box SIMPLY go:

    git clone http://project project 

finished.

Are there any robust and mature HTML parsers available for PHP? A quick skimming of PEAR didn&#39;t turn anything up (lots of classes for generating HTML, not so much for consuming), and Google taught me a lot of people have started and then abandoned a variety of parser projects.

Not interested in XML parsers (unless then can consume non-well formed HTML) or hacking it on my own with regular expressions.

&lt;strong&gt;Clarification of Intent: &lt;/strong&gt; I&#39;m not interested in filtering of HTML content, I&#39;m interesting in extracting information from HTML documents.

Does anyone know of a good YAML Parser for PHP? If so, what are the pros and cons of this library?

I&#39;m currently considering the use of Reflection classes (ReflectionClass and ReflectionMethod mainly) in my own MVC web framework, because I need to automatically instanciate controller classes and invoke their methods without any required configuration (&quot;convention over configuration&quot; approach).

I&#39;m concerned about performance, even though I think that database requests are likely to be bigger bottlenecks than the actual PHP code.

So, I&#39;m wondering if anyone has any good or bad experience with PHP 5 Reflection from a performance point of view.

Besides, I&#39;d be curious to know if any one of the popular PHP frameworks (CI, Cake, Symfony, etc.) actually use Reflection.

How do you convert a number to a string showing dollars and cents?

    eg:
    123.45    =&gt; &#39;$123.45&#39;
    123.456   =&gt; &#39;$123.46&#39;
    123       =&gt; &#39;$123.00&#39;
    .13       =&gt; &#39;$0.13&#39;
    .1        =&gt; &#39;$0.10&#39;
    0         =&gt; &#39;$0.00&#39;

**PHP has a [var_dump()][1] function which outputs the internal contents of an object, showing an object&#39;s type and content.**

For example:

    class Person {
      private $firstName;
      private $lastName;
    
      public function __construct($firstName, $lastName) {
        $this-&gt;firstName = $firstName;
    	$this-&gt;lastName = $lastName;
      }
    }
    
    $person = new Person(&#39;Jon&#39;, &#39;Smith&#39;);
    var_dump($person);

will output:

    object(Person)#1 (2) {
      [&quot;firstName:private&quot;]=&gt;
      string(3) &quot;Jon&quot;
      [&quot;lastName:private&quot;]=&gt;
      string(5) &quot;Smith&quot;
    }


**What is the equivalent in Java that will do the same?**

In through `php_info()` where the WSDL cache is held (`/tmp`), but I don&#39;t necessarily know if it is safe to delete all files starting with WSDL. 

Yes, I _should_ be able to just delete everything from `/tmp`, but I don&#39;t know what else this could effect if I delete any all WSDL files.

In PHP how can you clear a WSDL cache?

Suppose that I have a `&lt;div&gt;` that I wish to center in the browser&#39;s display (viewport). To do so, I need to calculate the width and height of the `&lt;div&gt;` element.

I need to display external resources loaded via cross domain requests and make sure to only display &quot;*safe*&quot; content. 

Could use Prototype&#39;s [String#stripScripts][1] to remove script blocks. But handlers such as `onclick` or `onerror` are still there.

Is there any library which can at least

  - strip script blocks,
  - kill DOM handlers,
  - remove black listed tags (eg: `embed` or `object`).

So are any JavaScript related links and examples out there?

Sanitize/Rewrite HTML on the Client Side

Lets say I am currently at:
`http://example.com/folder/page.html`

Is it possible to create a relative link on this page that points to `http://example.com/folder/` without specifying `folder` anywhere? (And using only HTML.)


**UPDATE:**
**As it turned out `./` works only in non-strict doctype mode, while `.` works in both modes, so it is still a better answer in my opinion :) 
Thanks everybody.**

How to set relative path to current folder?

I&#39;m reloading a web page that has the following code:

    &lt;label for=&quot;showimage&quot;&gt;Show Image&lt;/label&gt;
    &lt;input id=&quot;showimage&quot; name=&quot;showimage&quot; type=&quot;checkbox&quot; value=&quot;1&quot; /&gt;

Even though the HTML stays sent to the browser is the same for each reload of the page, the checkbox always takes on the checked value when a reload was performed.  In other words, if the user checks the checkbox and reloads, the checkbox is still checked.

Is there some caching going on here?  

__Edit__: I tried Gordon Bell&#39;s solution below and find that this is still happening even after removing the value=&quot;1&quot;.  Anything else I might be missing?

    &lt;label for=&quot;showimage&quot;&gt;Show Image&lt;/label&gt; 
    &lt;input id=&quot;showimage&quot; name=&quot;showimage&quot; type=&quot;checkbox&quot; /&gt; 



Why does the checkbox stay checked when reloading the page?

It seems like every question on stackoverflow where the asker is using regex to grab some information from HTML will inevitably have an &quot;answer&quot; that says not to use regex to parse HTML.

Why not? I&#39;m aware that there are quote-unquote &quot;real&quot; HTML parsers out there like [Beautiful Soup][1], and I&#39;m sure they&#39;re powerful and useful, but if you&#39;re just doing something simple, quick, or dirty, then why bother using something so complicated when a few regex statements will work just fine?

Moreover, is there just something fundamental that I don&#39;t understand about regex that makes them a bad choice for parsing in general?

Using regular expressions to parse HTML: why not?

I want to use the HTML agility pack to parse tables from complex web pages, but I am somehow lost in the object model.

I looked at the link example, but did not find any table data this way.
Can I use XPath to get the tables? I am basically lost after having loaded the data as to how to get the tables. I have done this in Perl before and it was a bit clumsy, but worked. (`HTML::TableParser`). 

I am also happy if one can just shed a light on the right object order for the parsing.

How do you parse HTML with a variety of languages and parsing libraries?

When answering:

Individual comments will be linked to in answers to questions about how to parse HTML with regexes as a way of showing the right way to do things.

For the sake of consistency, I ask that the example be parsing an HTML file for the `href` in anchor tags. To make it easy to search this question, I ask that you follow this format

Language: [language name]

Library: [library name]

    [example code]

Please make the library a link to the documentation for the library. If you want to provide an example other than extracting links, please also include:

From what I can make out, the two main HTML parsing libraries in Python are lxml and BeautifulSoup. I&#39;ve chosen BeautifulSoup for a project I&#39;m working on, but I chose it for no particular reason other than finding the syntax a bit easier to learn and understand. But I see a lot of people seem to favour lxml and I&#39;ve heard that lxml is faster.

So I&#39;m wondering what are the advantages of one over the other? When would I want to use lxml and when would I be better off using BeautifulSoup? Are there any other libraries worth considering?

Parsing HTML in python - lxml or BeautifulSoup? Which of these is better for what kinds of purposes?

I do a lot of HTML parsing in my line of work. Up until now, I was using the HtmlUnit headless browser for parsing and browser automation.

Now, I want to separate both the tasks.

I want to use a light HTML parser because it takes much time in HtmlUnit to first load a page, then get the source and then parse it.

I want to know which HTML parser can parse HTML efficiently. I need

1. Speed
2. Ease to locate any HtmlElement by its &quot;id&quot; or &quot;name&quot; or &quot;tag type&quot;.

It would be ok for me if it doesn&#39;t clean the dirty HTML code. I don&#39;t need to clean any HTML source. I just need an easiest way to move across HtmlElements and harvest data from them.
