Hello,
If I understand you correctly, first you could get this content control as RichTextContentControl object. Then you could use RichTextContentControl.Range property to get the text in this content control. For Range property, please refer to this thread: http://msdn.microsoft.com/en-us/library/microsoft.office.tools.word.richtextcontentcontrol.range.aspx.
Best regards,
Bessie
