You weren't that wordy about it at the time; you simply said your first impulse was to "blame GNU bash". That's a bit of a sore point -- BASH, as a shell many new users start with, has a low value in some admin's eyes -- the habit of new users calling all shell scripting "bash scripts" doesn't help -- and seems to get blamed for everything from their own bugs to poor weather as a result. Even though it's just doing what a Bourne shell does. Blame him if you must. Smilie

In my opinion, the ksh approach makes life a little easier.

Perhaps, but it's not something that can really be changed now. Bourne is what it is, and changing the ordering would change what happens in a lot of scripts because it cuts both ways -- suddenly scripts could be setting variables in the main shell they never did before...

I bet BASH'll add it as one of it's many fiddly setopt options someday.

pom_xpath_inject

POM_XPATH_INJECT(7)						Java Packages Tools					       POM_XPATH_INJECT(7)

NAME

       pom_xpath_inject - inject XML code into POM file

SYNOPSIS

       %pom_xpath_inject XPath [XML-code] [POM-location]

DESCRIPTION

       This macro patches specified POM file appending some code as childreen of all XML nodes described by the XPath expression.

       XPath is an expression describing a set of XML nodes in the POM file to which child code is to be appended. It must be a properly formated
       XPath 1.0 expression, as described in http://www.w3.org/TR/xpath/.

       POM location can be either a full path to the POM file, or a path to the directory containing pom.xml. If POM location is not given then
       pom.xml from current working directory is used.

EXAMPLES

       %pom_xpath_inject pom:project "<packaging>war</packaging>" - this call sets packaging of POM in current working directory to war.

BUGS

       POM files use a specific namespace - http://maven.apache.org/POM/4.0.0. Currently this namespace needs to be explicitly specified in all
       XPath POM macros by prefixing all node names with pom:.
