Shellscript Read XML attribute value

Question

We want to read XML attributes from an XML file. Example of file content is as below:

  
  <         


        

Answer 1

sed -n '/

Creates a hold pattern for the value then matches everything except for the newline to avoid printing the newline, it expects the value double quoted as per your example data.

E.g. 

  
  


Output:
15
