I have this xml file.
<body> <part1> <para1>abc</para1> <para2>def</para2> <ver>1234</ver> </part1> </body> I need to store the value given by ver i.e. 1234 in a variable.
- 1That question isn't quite a duplicate... It's about extracting an attribute value, not the body of a tag. The answer is going to be very similar, though - just a bit different XPath expression.– ShawnCommentedMar 18, 2021 at 7:02
- Yes @Shawn, I went through a lot of questions in which the value was present in the tag itself. I tried modifying those answers but couldn't reach a solution. Thanks for reopening.– YankeeCommentedMar 18, 2021 at 8:52

Different options:
- using
xmlstarlet:
ver=$(xmlstarlet sel -t -m //ver -v . test.xml) - using
xmllint(see also Native shell command set to extract node value from XML:
ver=$(xmllint --xpath "//ver/text()" test.xml) - Using
gawk:
ver=$(gawk -F "[><]" '/<ver>/{ print $3 }' test.xml) 
- 2The awk one (and it's common to all awks, not gawk-specific) would be more robust as
awk -F'[<>]' '$2=="ver"{ print $3 }'. That would not fail if<ver>just happened to exist in some other string in the input.CommentedMar 18, 2021 at 16:35 - 2
