'Usage
 
Dim ds As DicomDataSet

Dim cbBefore As LoadXmlBeforeElementCallback
Dim cbAfter As LoadXmlAfterElementCallback
 
DicomExtensions.LoadXml(ds, fileName, xmlFlags, cbBefore, cbAfter)

Parameters

ds: The Data Set that will be created and populated with the contents of the DICOM xml input file
fileName: The name of the input xml file
xmlFlags: Flags that affect whether to ignore binary or all data from the DICOM xml input file
cbBefore: Optional callback that allows you to modify how the input xml file elements, attributes, and values are used.
cbAfter: Optional callback that allows you to change the Leadtools.Dicom.DicomElement after it has been added to the Leadtools.Dicom.DicomDataSet.

Use this method to read the contents of a DICOM xml file. The DICOM xml file can be created using SaveXml(DicomDataSet,Stream,DicomDataSetSaveXmlFlags,SaveXmlCallback) By default, all binary data is read from the DICOM input xml file, but this behavior can be modified by passing appropriate DicomDataSetLoadXmlFlags

The way the that this method processes the input xml file elements, attributes, and element values can be customized by passing the optional LoadXmlBeforeElementCallback delegate. For more information on this, see the documentation and example for LoadXmlBeforeElementCallback. The Leadtools.Dicom.DicomElement themselves can be modified after they have been added to the Leadtools.Dicom.DicomDataSet by passing the optional LoadXmlAfterElementCallback delegate. For more information on this, see the documentation and example for LoadXmlAfterElementCallback.
