# CFXMLTreeCreateFromData

Parses the given XML data and returns the resulting CFXMLTree object.

```
extern CFXMLTreeRefCFXMLTreeCreateFromData(CFAllocatorRef allocator, CFDataRef xmlData, CFURLRef dataSource, CFOptionFlags parseOptions, CFIndex versionOfNodes);
```

## Parameters

`allocator`

The allocator to use to allocate memory for the new object. Pass `NULL` or kCFAllocatorDefault to use the current default allocator.

`xmlData`

The XML data you wish to parse.

`dataSource`

The URL from which the XML data was obtained. The URL is used to resolve any relative references found in `xmlData`. Pass `NULL` if a valid URL is unavailable.

`parseOptions`

Flags which control how the XML data will be parsed. See [`CFXMLParserOptions`](/documentation/CoreFoundation/CFXMLParserOptions) for the list of available options.

`versionOfNodes`

Determines which version of CFXMLNode objects are produced by the parser.

## Return Value

A new CFXMLTree object containing the data from the specified XML document. Ownership follows the [The Create Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-103029).

## Discussion

This function represents the high-level interface to the XML parser. This single function creates a parser for the specified XML data using the specified options. The parser creates and returns a CFXMLTree object that you can examine and modify with the CFTree functions or obtain the node using the [`CFXMLTreeGetNode`](/documentation/CoreFoundation/CFXMLTreeGetNode) function and examine its attributes using CFXMLNode functions.
