Question

I have a string here, This is a string: AAA123456789.

So the idea here is to extract the string AAA123456789 using regex.

I am incorporating this with X-Path.

Note: If there is a post to this, kindly lead me to it.

I think, by right, I should substring(myNode, [^AAA\d+{9}]),

I am not really sure bout the regex part.

The idea is to extract the string when met with “AAA” and only numbers but 9 consequent numbers only.

Answer 1

Pure XPath solution:

substring-after('This is a string: AAA123456789', ': ')

produces:

AAA123456789

XPath 2.0 solutions:

tokenize('This is a string: AAA123456789 but not an double',
              ' '
              )[starts-with(., 'AAA')]

or:

tokenize('This is a string: AAA123456789 but not an double',
              ' '
              )[matches(., 'AAA\d+')]

or:

replace('This is a string: AAA123456789 but not an double',
              '^.*(A+\d+).*$',
              '$1'
              )
