Usage

Installation

The recommended way to install the extension is using Composer.

Run the following command:

composer require simonschaufi/pretty-xml

How to use

Prettify

To use, give it a badly indented (but well-formed and valid) XML string:

use PrettyXml\Formatter;

$formatter = new Formatter();
echo "<pre>" . htmlspecialchars($formatter->format('<?xml version="1.0" encoding="UTF-8"?><foo><bar>Baz</bar></foo>')) . "</pre>";

You can also change the size of the indent:

$formatter->setIndentSize(2);

And you can change the indent character:

$formatter->setIndentCharacter("\t");

Minify

use PrettyXml\Formatter;

$formatter = new Formatter();
echo htmlspecialchars($formatter->minify(<<<XML
<?xml version="1.0" encoding="UTF-8"?>
<foo>
 <bar>Baz</bar>
</foo>
XML));

// keep comments
echo htmlspecialchars($formatter->minify(<<<XML
<?xml version="1.0" encoding="UTF-8"?>
<foo>
 <!-- comment -->
 <bar>Baz</bar>
</foo>
XML, true));
