## Codeception\Util\XmlBuilder
That's a pretty simple yet powerful class to build XML structures in jQuery-like style.
With no XML line actually written!
Uses DOM extension to manipulate XML data.
```php
<?php
$xml = new \Codeception\Util\XmlBuilder();
$xml->users
->user
->val(1)
->email
->val('davert@mail.ua')
->attr('valid','true')
->parent()
->cart
->attr('empty','false')
->items
->item
->val('useful item');
->parents('user')
->active
->val(1);
echo $xml;
```
This will produce this XML
```xml
<?xml version="1.0"?>
<users>
<user>
1
<email valid="true">davert@mail.ua</email>
<cart empty="false">
<items>
<item>useful item</item>
</items>
</cart>
<active>1</active>
</user>
</users>
```
### Usage
Builder uses chained calls. So each call to builder returns a builder object.
Except for `getDom` and `__toString` methods.
* `$xml->node` - create new xml node and go inside of it.
* `$xml->node->val('value')` - sets the inner value of node
* `$xml->attr('name','value')` - set the attribute of node
* `$xml->parent()` - go back to parent node.
* `$xml->parents('user')` - go back through all parents to `user` node.
Export:
* `$xml->getDom` - get a DOMDocument object
* `$xml->__toString` - get a string representation of XML.
