I extended SimpleXml and added this code to give me pleasant source code XML.
<?php
public function asPrettyXML()
{
$string = $this->asXML();
/**
* put each element on it's own line
*/
$string =preg_replace("/>\s*</",">\n<",$string);
/**
* each element to own array
*/
$xmlArray = explode("\n",$string);
/**
* holds indentation
*/
$currIndent = 0;
/**
* set xml element first by shifting of initial element
*/
$string = array_shift($xmlArray) . "\n";
foreach($xmlArray as $element) {
/** find open only tags... add name to stack, and print to string
* increment currIndent
*/
if (preg_match('/^<([\w])+[^>\/]*>$/U',$element)) {
$string .= str_repeat(' ', $currIndent) . $element . "\n";
$currIndent += self::indent;
}
/**
* find standalone closures, decrement currindent, print to string
*/
elseif ( preg_match('/^<\/.+>$/',$element)) {
$currIndent -= self::indent;
$string .= str_repeat(' ', $currIndent) . $element . "\n";
}
/**
* find open/closed tags on the same line print to string
*/
else {
$string .= str_repeat(' ', $currIndent) . $element . "\n";
}
}
return $string;
}
?>

I extended SimpleXml and added this code to give me pleasant source code XML. I'm sure
it's ugly so if you can do it better go ahead...
<?php
public function asPrettyXML()
{
$string = $this->asXML();
/**
* put each element on it's own line
*/
$string =preg_replace("/>\s*</",">\n<",$string);
/**
* each element to own array
*/
$xmlArray = explode("\n",$string);
/**
* holds indentation
*/
$currIndent = 0;
/**
* set xml element first by shifting of initial element
*/
$string = array_shift($xmlArray) . "\n";
foreach($xmlArray as $element) {
/** find open only tags... add name to stack, and print to string
* increment currIndent
*/
if (preg_match('/^<([\w])+[^>\/]*>$/U',$element)) {
$string .= str_repeat(' ', $currIndent) . $element . "\n";
$currIndent += self::indent;
}
/**
* find standalone closures, decrement currindent, print to string
*/
elseif ( preg_match('/^<\/.+>$/',$element)) {
$currIndent -= self::indent;
$string .= str_repeat(' ', $currIndent) . $element . "\n";
}
/**
* find open/closed tags on the same line print to string
*/
else {
$string .= str_repeat(' ', $currIndent) . $element . "\n";
}
}
return $string;
}
?>
