IXMLGraphBuilder Interface
The IXMLGraphBuilder interface is used to persist a DirectShow filter graph using an XML file format. To get a pointer to this interface, call CoCreateInstance with the class identifier CLSID_XMLGraphBuilder.
- **Note **This interface is deprecated, and new applications should not use it. The recommended way to save and load a filter graph is to use the GraphEdit file format:
Generally, you should persist a filter graph only for testing purposes and not for production. There is no consistently reliable way to reload a filter graph from a file, because the user's hardware and software configurations can change between sessions. Therefore, except for testing, an application should always build a filter graph programmatically.
In addition to the methods inherited from IUnknown, the IXMLGraphBuilder interface exposes the following methods.
| Method | Description |
| BuildFromXML | Loads a filter graph from an XML element. |
| BuildFromXMLFile | Loads a filter graph from an XML file. |
| SaveToXML | Saves a filter graph to an XML element. |
