if __name__ == "__main__": #import and other stuff print "Updating cached Dashboards dictionary Name->Uuid\n" from xml.dom.minidom import parse import os import re dashboards={} #load the dictionnary from external source for file in os.listdir(T04Path.T04DashboardsDashboardsPath): if't04panel$',file): print "Processing file %s\n"%file dom=parse(os.path.join(T04Path.T04DashboardsDashboardsPath,file)) dashboards[dom.getElementsByTagName("Panel")[0].attributes["Name"].value]=dom.getElementsByTagName("Panel")[0].attributes["Uuid"].value #keep it on a file so that is accessible inside the Dashboards persistence.set('Dashboards',dashboards,IronPython=False)
