How do I extract substring from string?

Question

I have an xml string here from which I need to identify the values and leave out names from it. The logic I thought is to extract all strings which are in between of

> and </.

Then remove any extracted substring which has  >,< or </ in it

XML string is:

<ServiceInstanceUpdateAck xmlns='http://www.loremipsum.com/'>
  <Context>
    <Attribute name='Atri1'>A1</Attribute>
    <Attribute name='Atri2'>A2</Attribute>
  <Attribute name='Atri3'>A3</Attribute>
  </Context>
  <Operation>DEPROVISION</Operation>
  <Status>SUCCESS</Status>
  <Error message='No Error' majorErrorCode='E_NONE' minorErrorCode='E_NONE'/> 
  <Service>
    <Id>11233334</Id>
  </Service> 
</ServiceInstanceUpdateAck>

What will be the python code for that? I am learning python and not that good with strings yet. Any help is appreciated.

The correct way of doing this is to use XML parser. I wonder why are you not using it. Did you look at this http://stackoverflow.com/questions/14153988/how-should-i-parse-this-xml-string-in-python?

You should not treat XML in this way, use a proper XML parser such as 20.6. xml.dom — The Document Object Model API — Python 3.3.6 documentation[^].
