regex - Schematron regexp:test fails with broad expression -

i going nuts here..

the test fails using broad match-anything regex '^.+$' (shown in sample file) works specific '^c.+$'

i tried test="string-length(.) > 0" , fails.

please help.

it seems backslashes in xsl can used define escape sequences. when need define regex shorthand character class, need prepend specific characters literal backslash, thus, need use double backslash:

^[\\s\\s]+$ 

this pattern match:

• ^ - start of string
• [\\s\\s]+ - 1 or more characters either whitespace or non-whitespace (thus, matches character)
• $ - end of string.

this means regex flavor not javascript, althoug this reference claims exslt uses js flavor.
