.SS "void discover_data_free (\fBdiscover_data_t\fP * data_tree)"
.PP
Free the data tree. Note that unlike the other free functions in Discover, this one does not free data_tree itself. This is a side-effect of how it is implemented. It frees all children and siblings of data_tree as well as the data. After calling discover_data_free, you have to call free(3) on data_tree itself.

.PP
Get the data matching the class path and version number (optional) from the device structure.
.PP
The class parameter requires further explanation. The XML data sources have hierarchical data elements for each device. You access the data in an element by specifying the path along the data elements to it.
.PP
For example, device elements for video cards usually have a data element of class 'xfree86' containing data related to the XFree86 package; that element itself usually contains a data element of class 'server' that specifies which server to use for this video card. You access this data by passing the string 'xfree86/server' to this function.
