xpath - X-Path + RegEx matching pattern -


given following,

<line>     <supplier>fuel surcharge - 36</supplier>     <supplier>fuel surcharge - 35</supplier>     <supplier>46081 46150 46250 46280 46286</supplier>     <supplier>fuel surcharge - 35451</supplier>     <supplier>46081</supplier> </line>

the idea here return "true" when node carries number of 5 digits iteration.

this have done far,

matches(./supplier, "[^(\d{5}\s*)+]");

the regex here extract value has 5 digits or without space regardless of iteration.

the results getting true. means not right somewhere. can assist me this.

thanks.

there 2 problems expression:

  • no semicolon in end of xpath expression (syntax error).
  • your regex messed up, matches not contain out of character class parentheses, digits, curly brackets, digit 5, spaces, , star , plus character.
  • fn:matches(xs:string?, xs:string) requires 2 strings parameters, you're passing sequence of strings first one.

to call function for each node in axis step, add 1 (xpath 2.0 , above only). can use dot . (context) in arguments.

try like

./supplier/matches(., "^(\d{5}\s*)+$")

which yield true third , fifth row. if must contain (and not constructed from) repeating pattern of fife-digit-numbers , spaces, remove ^ , $ regular expression.
