      (Chilkat2-Python) Find and Update an XML Attribute ValueSee more XML ExamplesDemonstrates how to find an element in XML with a specified attribute name and then update the attribute value.
 import chilkat2 # Let's say you have 2 XML files with identical structures as shown directly below, # and you wish to update the values in the 1st XML file with those in the 2nd XML file. # <global> # <phrase id="2FADisabled" value="2factor authentication disabled"/> # <phrase id="2FAEnabled" value="2factor authentication enabled"/> # <phrase id="2FAResetFailed" value="Failed to disable two factor authentication"/> # </global> # <global> # <phrase id="2FAResetFailed" value="Failed to reset two factor authentication"/> # <phrase id="2FADisabled" value="2FA authentication disabled"/> # <phrase id="2FAEnabled" value="2FA authentication enabled"/> # </global> # First, initialize each of the Chilkat XML objects. # These could be loaded from files, but we'll just create them manually for this example.. xml1 = chilkat2.Xml() xml1.Tag = "global" xml1.UpdateAttrAt("phrase",True,"id","2FADisabled") xml1.UpdateAttrAt("phrase",True,"value","2factor authentication disabled") xml1.UpdateAttrAt("phrase[1]",True,"id","2FAEnabled") xml1.UpdateAttrAt("phrase[1]",True,"value","2factor authentication enabled") xml1.UpdateAttrAt("phrase[2]",True,"id","2FAResetFailed") xml1.UpdateAttrAt("phrase[2]",True,"value","Failed to disable two factor authentication") xml2 = chilkat2.Xml() xml2.Tag = "global" xml2.UpdateAttrAt("phrase",True,"id","2FAResetFailed") xml2.UpdateAttrAt("phrase",True,"value","Failed to reset two factor authentication") xml2.UpdateAttrAt("phrase[1]",True,"id","2FADisabled") xml2.UpdateAttrAt("phrase[1]",True,"value","2FA authentication disabled") xml2.UpdateAttrAt("phrase[2]",True,"id","2FAEnabled") xml2.UpdateAttrAt("phrase[2]",True,"value","2FA authentication enabled") # Iterate over attribute values in xml2 and update the same in xml1. sbPath = chilkat2.StringBuilder() i = 0 count_i = xml2.NumChildrenHavingTag("phrase") while i < count_i : xml2.I = i phrase_id = xml2.ChilkatPath("phrase[i]|(id)") phrase_value = xml2.ChilkatPath("phrase[i]|(value)") # Notice how the UpdateAttrAt method's 1st argument is a Chilkat path -- which is an expression # to find the location of the XML element to be updated. # Here we create a path of the form "/A/tagName,attributeName,attributeValuePattern", which means # find the direct descendent of xml2 having tag=tagName, with an attribute=attributeName where the attribute value # matches the attributeValuePattern. If attributeValuePattern does not contain a "*", then it must match directly. # We'll build a Chilkat path such as "/A/phrase,id,2FADisabled" sbPath.SetString("/A/phrase,id,") sbPath.Append(phrase_id) # This assumes the corresponding element exists in xml1. xml1.UpdateAttrAt(sbPath.GetAsString(),True,"value",phrase_value) i = i + 1 # Now see how xml1 has been updated.. print(xml1.GetXml()) # <global> # <phrase id="2FADisabled" value="2FA authentication disabled"/> # <phrase id="2FAEnabled" value="2FA authentication enabled"/> # <phrase id="2FAResetFailed" value="Failed to reset two factor authentication"/> # </global>  |
