First of all, we expand `\w' into ``any letter or digit or the
underscore character'' [1]:
echo "$DATA" \
| sed -e "s/<Name>\s*\([[:alpha:][:digit:]_]*\)/~\1~/g" \
-e "s/<\/Name>//g"
## => ~Foo~ Bar Baz
Then, we add `[:space:]' to the []-set:
echo "$DATA" \
| sed -e "s/<Name>\s*\([[:alpha:][:digit:][:space:]_]*\)/~\1~/g" \
-e "s/<\/Name>//g"
## => ~Foo Bar Baz~
Finally, I'd recommend to use single quotes for the Sed program,
since it has no Shell substitutions contained within:
echo "$DATA" \
| sed -e 's/<Name>\s*\([[:alpha:][:digit:][:space:]_]*\)/~\1~/g' \
-e 's/<\/Name>//g'
## => ~Foo Bar Baz~
