Using xpath_eval in External Tool

[michaelmh]

Hi all,

I want to make a call to an external tool OS independent, and because it is either a BAT or a SH file, I thought of using $xpath_eval() to check out os.name for differentiation. I tested the behavior inside the $ask editor variable.

After some testing, I think that "if … then … else …" is not supported in the XPath expression.

This works, i.e. the default value is filled:

[Codebox=]${ask(
'${system(os.name)}',
generic,
'${xpath_eval(
upper-case('${system(os.name)}')
)}'
)}[/Codebox]

This does not work, i.e. the default value is empty but should be the same:

[Codebox=]${ask(
'${system(os.name)}',
generic,
'${xpath_eval(
if true() then upper-case('${system(os.name)}') else 'NOPE'
)}'
)}[/Codebox]

What have I got wrong?

Hello,

There's a syntax error inside the XPath expression. The "if" condition must be between parentheses, like this:

Code: Select all

if (true()) then upper-case('${system(os.name)}') else 'NOPE'

I see that we log these a warning inside the console when there are exceptions with the XPath expression. Perhaps we should present that error directly inside the interface so that you understand what's wrong...

Best regards,
Alex

Thanks,

Better reporting of such errors would indeed be welcome. I was looking for the Java Console (on Mac OS) but could not find it, or is this only accessible to developers?

Hi,

If you start the .app launcher, the output of the console is redirected to the output.log and the errors to the error.log files kept in the Oxygen folder.
If you start the application via the .sh script in a Terminal, you will see the logged messages directly in the Terminal window.
