Ok, I'm trying to do some simple expressions to manipulate some values,
but I'm not having luck nesting expressions. Specifically, I can not
figure out how to use a function as a argument to another function.
This means I have to use incremental steps and assign the value to a
property, then reference that property in a later step rather then doing
it in a single step. Is it possible to use a function as an arugument
to another function?
Something like..
Value=${stringsubstring(property1, property2, string::length(property3)
- property4}
Any combination I try to nest an expression inside another fails.
I'm also having a problem with specifying properties properly inside an
expression
Here's what I'm trying to do..
I have a string in a property. I need to get the index location of a
substring, add to that number, get the overall length of the string, do
a subtraction of those two numbers, and then use these two numbers to
get a substring. The pseudo code would be something like this
Position = string::Pindex-of(string, value) + 11
targetlength = string::length(string) - $position
result = string::substring(string, position, targetlength)
My code currently is
<target name="test">
<loadfile file="setup.log" property="deploySetupLogContents" />
<property name="position"
value="${string::index-of(deploySetupLogContents,'ResultCode=') + 11}"/>
<property name="length"
value="${string::get-length(deploySetupLogContents) - position}"/>
<property name="deploySetupResultCode"
value="${string::substring(deploySetupLogContents, position, length)}"/>
<echo>Result Code is ${deploySetupResultCode}</echo>
</target>
But the above does not work. It complains that in line 4, it can't do
the subtraction between an 'int' and 'string'. Position is not a
string.. it's a property which is holding an init from line 3. I can't
specify it as ${position}.. so how can I reference the value I need
here? I need the entire thing inside an ${ } so its evaluated as an
expression and not just saved as a string.
