With xmlstalet tool:

xmlstarlet sel -t -v "//SOUNDCHEK/InFrame" -n input.xml
  • //SOUNDCHEK/InFrame - xpath expression to select all InFrame nodes which are children of SOUNDCHEK nodes

The output:

2
4
7

Try using xmllint and select the required data with a xpath.

xmllint --xpath '/APP/SOUNDCHECK/InFrame/text()' file.xml
