replacing xml parent tag with some of its child tags using xml.dom in python

Question

The following is the part of the XML code source:

<FacilitySite>
    .    
    .
    .
     <Program>
             .        
             .        
             .        
             <ProgramProfileElectronicAddress>
                        <ElectronicAddressText>http://example.com</ElectronicAddressText>
                        <ElectronicAddressTypeName>URL</ElectronicAddressTypeName>  </ProgramProfileElectronicAddress>
    </Program>
</FacilitySite>

<FacilitySite>
    .    
    .
    . 
    <Program>
            .        
            .        
            .        
            <ProgramProfileElectronicAddress>
                    <ElectronicAddressText>http://example.com</ElectronicAddressText>
                    <ElectronicAddressTypeName>URL</ElectronicAddressTypeName> </ProgramProfileElectronicAddress>
    </Program>
    <Program>
            .        
            .        
            .        
            <ProgramProfileElectronicAddress>
                    <ElectronicAddressText>http://example.com</ElectronicAddressText>
                    <ElectronicAddressTypeName>URL</ElectronicAddressTypeName> </ProgramProfileElectronicAddress>
    </Program>
</FacilitySite>

<FacilitySite>
   .
   .
   .
</FacilitySite>
.
.
.

In the above xml code, assume 10 FacilitySite tags,there may be no program tag in some of them, but may exist multiple program tags in the rest. I want to convert the above code to the following xml code using xml.dom (i.e., I want to remove the program tag with its child tags except the ElectronicAddressText tag. Also, I want to add the URL tag to the content of the ElectronicAddressText tag.):

<FacilitySite>
     .    
     .    
     .    
     <ElectronicAddressText>
         <URL>http://example.com</URL>
     </ElectronicAddressText>
</FacilitySite>

<FacilitySite>
    .    
    .    
    .    
    <ElectronicAddressText>
        <URL>http://example.com</URL>
    </ElectronicAddressText>
    <ElectronicAddressText>
        <URL>http://example.com</URL>
    </ElectronicAddressText>
</FacilitySite>
<FacilitySite>
     .    
     .    
     .    
     <ElectronicAddressText>
         <URL>http://example.com</URL>
     </ElectronicAddressText>
</FacilitySite><FacilitySite>
     .    
     .    
     .
</FacilitySite>
.
.
.

I tried to run the following code but I faced with AttributeError: 'NodeList' object has no attribute 'nodeType'

from xml.dom.minidom import parse
import xml.dom.minidom
# Open XML document using minidom parser
DOMTree = xml.dom.minidom.parse("example.xml")

EPAs = DOMTree.getElementsByTagName("FacilitySite")

for EPA in EPAs:
   program_nodes = EPA.getElementsByTagName("Program")
   for program_node in program_nodes:
       ElectronicAddressText_node = program_node.getElementsByTagName("ElectronicAddressText")
       parent = program_node.parentNode
       parent.replaceChild(ElectronicAddressText_node, program_node)

       print(EPA.toxml())
