pretty-xml

A tiny library for pretty printing XML, inspired purely from DomDocument's lack of ability to configure indent distance.

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));
