Print XML element with AWK

Question

How do I print the contents of an XML element - from the starting tag to the closing tag - using AWK?

For example, consider the following XML:

Answer 1

$ awk -v tag='city' '$0~"^<"tag"\\>"{inTag=1} inTag; $0~"^"{inTag=0}' file

       Athens
       GA
        Home of the University of Georgia
       100,000
       Located about 60 miles Northeast of Atlanta
       33 57' 39" N
       83 22' 42" W

Using GNU awk above for \> word boundary functionality. With other awks use [^[:alnum:]_] or similar.

To only print the first occurrence:

$ awk -v tag='city' '$0~"^<"tag"\\>"{inTag=1} inTag{print; if ($0~"^") exit}' file

       Athens
       GA
        Home of the University of Georgia
       100,000
       Located about 60 miles Northeast of Atlanta
       33 57' 39" N
       83 22' 42" W
