示例1: addQuotesAndStripTags
/**
* convert blockquotes to quotes ("> ") and strip tags
*
* this function uses tidy or DOM to recursivly walk the dom tree of the html mail
* @see http://php.net/manual/de/tidy.root.php
* @see http://php.net/manual/en/book.dom.php
*
* @param tidyNode|DOMNode $_node
* @param integer $_quoteIndent
* @param string $_eol
* @return string
*
* @todo we can transform more tags here, i.e. the <strong>BOLDTEXT</strong> tag could be replaced with *BOLDTEXT*
* @todo think about removing the tidy code
* @todo reduce complexity
