Thanks XL. I do not see single quotes in properties, I will try to wrap values in single quotes first, then use your script to expand variable substitution. Thanks for taking time to look into it.

props are defined for huge real world app, I can't change existing format.
If its just keyName I would have replaced '.' with '_' and back. values have all kinds of special characters like '='

I want to read properties from a file and print evaluated values of each key.
I am using AIX6.1.

Here is simplified case..
perl one liner can get quite big if we have to extract more fields from XML.
So how can we break text in single quotes perl -nle '</regex/ and all kinds of logic'...

Below code extracts multiple field values from XML into array and prints all in one line.

perl -nle '@r=/(?: jndiName| authDataAlias| value| minConnections| maxConnections| connectionTimeout|...

Don,
With awk I am noticing wild swings within few minutes gap. At the same time perl solution performance is pretty consistent with little variation.

I am dropping my original solution from...

I have SuSe Linux 11 VM with 8GM RAM(300 MB free) 2 CPU cores.


# XML has 151 matching xml nodes(lines)

performance is same with in-line first part of regex in perl vs grep + perl.

Can you explain what is the meaning of below two expressions in your command?

'?:'
"([^"]+)

Aia, thanks for trying,, I knew a wicked one liner like you gave could do this..
Don, please check performance stats,, I am bash/awk lover,, we have work to do..
