Xml-Array

The conversion between xml and array becomes easier than ever. This package provides some very simple classes to convert XML to array and back.

Features of this package

• Convert an XML object (DOMDocument, SimpleXMLElement) or well-formed XML string to an associative array or Json string.
• Convert an associative array to well-formed XML string or DOMDocument.
• Support parsing and building attributes, Cdata sections and namespaces of XML in conversion process.

Installation

You can install this package through Composer.

Basic usage

Convert from XML

Web have two following methods:

Convert to array:

Convert to Json:

Note: The input XML can be one of types DOMDocument object, SimpleXMLElement object or well-formed XML string.

Example 1: - (Convert from XML string)

After running this piece of code $array will contain:

Example 2: - (Convert form XML object, such as SimpleXMLElement)

The result of above code is:

Example 3: - (Convert to Json)

Convert from array

We also have two following methods:

Convert to XML string:

Convert to DOMDocument object:

Example 4:

Example 5:

Advanced usage

Set configuration

If we want to change the settings for the conversion process, we can do it in the following ways:

Method 1

Note: Configuration is an array of parameters. For more details, see section Default configuration.

Method 2

Method 3

Get configuration

If we implemented the conversion process using methods 2 and 3, we can get configuration of the conversion with method:

Default configuration

For Xml2Array

For Array2Xml

Effect of configuration settings

version

Effect: This setting allows specifying the XML version to be generated (in Array2Xml), or reconstructed from the XML string (in Xml2Array)

encoding

Effect: This setting is to indicate the encoding type of the XML to be generated (in Array2Xml), or reconstructed from the XML string (in Xml2Array)

standalone

Effect: This setting is to allow the standalone directive to appear in the XML or not. If it is set to null, this directive will not appear.

Example:

Content in $xml will be

attributesKey, cdataKey, valueKey

Effect: This setting allows the use of special keywords to contain the values ​​of properties, CDATA section... during the conversion process.

Example: Please review the examples above for more detailed understanding.

namespacesOnRoot

Effect: This setting allows to collect all the parsed XML namespaces and place them in the root node. If it is set to false, the namespaces will be located at the nodes where it is declared.

Example: We use the Example 1 above again, but this time the configuration is different:

After running this piece of code $array will contain:

You see, the xlmns:example namespace is put at the example:with_namespace key, not at root_node as it was originally.

rootElement

Effect: According to the Well-formed XML standard, the XML content is only allowed to have a single Root node. This setting allows to wrap all the elements of the original array into a single root node, instead of having to manually edit your array.

keyFixer

Effect:

According to the Well-formed XML standard, the tag names and attributes must satisfy a number of requirements, in which naming is specified as follows:

• Only allowed to start with aphabet characters and underscore.
• Only accept the [a-zA-Z], -, _, ., : characters. In which, the : is used to indicate the namespace prefix.
• Do not allow to end with :

During conversion, array key names that violate these rules are automatically normalized. If you do not agree to this normalization, set this setting to false.

By default, this normalization replaces invalid characters with underscores (_). You can change to another character as you like.
