simplexmlwriter.php - A Simple PHP Atom Feed Generator

`simplexmlwriter.php` - A string based XML writer

What it is and what it does

simplexmlwriter.php is an easy to use XMl generation class written in PHP. It simplifies the generation of XML documents by allowing XML to be generated through a series of function calls, tidying up your code and improving readability.

Example

add_xslt("https://example.com/test.xslt");	//add an xslt stylesheet
	$xml->open("root"); //open the root tag (although you could call it anything)
	
	//loop 10 times
	foreach(range(1, 10) as $i)
	{
		$xml->open("number"); //open a  tag
			$xml->addtag("type", ["foo" => "bar"], "integer"); //open and close a tag, adding text and attributes in one go
			$xml->open("value"); //open a  tag
				$xml->addtext($i); //add some text
			$xml->close(); //close the  tag
		$xml->close(); //close the  tag
	}
	$xml->closeall(); //close any other tags that are still open
	
	//------------------
	
	header("content-type: application/xml"); //set the appropriate header
	echo($xml->render()); //send the XML to the requester
?>

Reference

Name	Type	Description
`xml_doctype`	constant	The XML doctype that will be inserted at the top of the document
`generator_info`	constant	A string that will be inserted just below the doctype in a comment detailsing the generator that was used.
`prettyprint`	property	Whether the XML should be formatted (prettyprinted) or not. remember to set this before you start generating any XML as this generator is string based, and will not go back and change anything once you have changed it. Defaults to true.
`add_xslt($url = "")`	function	Add an XSLT stylesheet to the document. remember to call this before opening the first tag.
`open($tagname = "root", $attributes = [])`	function	Open a tag with the given name with the given attribute. The attributes should be an array in the from `["name1" => "value1", "name2" => "value2"]`.
`addtext($text = "", $newline = true)`	function	Add some text to the xml document. the `$newline` argument indicated whether a newline character should be added after the text.
`close()`	function	Close the last tag that was opened.
`closeall()`	function	Close all opened tags.
`addtag($tagname = "root", $attributes = [], $text = "")`	function	Add a tag with the name `$tagname` and then close it again. Attributes can be specified through an array (see the `open()` function above for detail on how to specify attributes), and text can be added through the `$text` argument. Pass an empty array to skip adding attributes.
`addcomment($text = "")`	function	Add a comment containing the given text.
`render()`	function	Render the xml and return the output. All open tags are closed in the rendering, but are left open in the main document so you can continue to add to the xml document after rendering.
`__toString()`	function	Alias to `render()`. Allows you to pass the document itself to functions, like this: `echo($myxml);` instead of `echo($myxml->render())`
