/**
* Searches $content for tags and returns information about each found tag.
*
* Created to support button replacing process, e.g. wrapping submit/reset
* inputs and buttons with artisteer style.
*
* When all the $name tags are found, they are processed by the $filter specified.
* Filter is applied to the attributes. When an attribute contains several values
* (e.g. class attribute), only tags that contain all the values from filter
* will be selected. E.g. filtering by the button class will select elements
* with class="button" and class="button validate".
*
* Parsing does not support nested tags. Looking for span tags in
* <span>1<span>2</span>3</span> will return <span>1<span>2</span> and
* <span>2</span>.
*
* Examples:
* Select all tags with class='readon':
* artxFindTags($html, array('*' => array('class' => 'readon')))
* Select inputs with type='submit' and class='button':
* artxFindTags($html, array('input' => array('type' => 'submit', 'class' => 'button')))
* Select inputs with type='submit' and class='button validate':
* artxFindTags($html, array('input' => array('type' => 'submit', 'class' => array('button', 'validate'))))
* Select inputs with class != 'art-button'
* artxFindTags($html, array('input' => array('class' => '!art-button')))
* Select inputs with non-empty class
* artxFindTags($html, array('input' => array('class' => '!')))
* Select inputs with class != 'art-button' and non-empty class:
* artxFindTags($html, array('input' => array('class' => array('!art-button', '!'))))
* Select inputs with class = button but != 'art-button'
* artxFindTags($html, array('input' => array('class' => array('button', '!art-button'))))
*

* name, attributes, raw_open_tag, body.
