How to remove XML tags from Unix command line?

If your file looks just like that, then sed can help you:

sed -e 's/<[^>]*>//g' file.xml

xml shell unix command-line xml-parsing

Using awk:

awk '{gsub(/<[^>]*>/,"")};1' file.xml

Give this a try:

grep -Po '<.*?>\K.*?(?=<.*?>)' inputfile

Explanation:

Using Perl Compatible Regular Expressions (-P) and outputting only the specified matches (-o):

<.*?> - Non-greedy match of any characters within angle brackets
\K - Don't include the preceding match in the output (reset match start - similar to positive look-behind, but it works with variable-length matches)
.*? - Non-greedy match stopping at the next match (this part will be output)
(?=<.*?>) - Non-greedy match of any characters within angle brackets and don't include the match in the output (positive look-ahead - works with variable-length matches)
