How to retrieve regex pattern value in schema ?

[Jing Yang]

Use xerces_2_9_0 schema  API to load  specified  schema( see below)  and
print out retrieved pattern values.

StringList patterns= simpleType.getLexicalPattern();

Int size=patters.getLength();

for(int i=0; i< size; i++){

      System.out.println("index "+index+ "  regex : " + patterns.item(i));

}

 

The result as :

index of 0   regex : [0-9]{1,3}

index of 1   regex : [\-+]?[0-9]+

 

Why does I get extral  pattern value  of  "[\-+]?[0-9]+" ?
