There is currently no mechanism to convert JSON back into a node tree. Furthermore, not all ASTs
can be JSON encoded. In particular, JSON only supports UTF-8 strings.
Serialization to XML
--------------------
It is also possible to serialize the node tree to XML using `PhpParser\Serializer\XML->serialize()`
and to unserialize it using `PhpParser\Unserializer\XML->unserialize()`. This is useful for
interfacing with other languages and applications or for doing transformation using XSLT.
```php
<?php
$code = <<<'CODE'
<?php
function printLine($msg) {
echo $msg, "\n";
}
printLine('Hello World!!!');
CODE;
$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7);
$serializer = new PhpParser\Serializer\XML;
try {
$stmts = $parser->parse($code);
echo $serializer->serialize($stmts);
} catch (PhpParser\Error $e) {
echo 'Parse Error: ', $e->getMessage();
}
```
Produces:
