Does anyone have an example of how to use regexsplit

[Leonard Kroll]

Ok

If I am understanding the regexsplit documentation page correctly .....

After applying the regular expression, "group(0) is returned as the result.

Is this correct, because I am not getting "Faculty" returned as the attribute value.

I get this line in the logs:



14:21:34.789 - DEBUG [edu.internet2.middleware.shibboleth.common.attribute.resolver.provider.attributeDefini

tion.RegexSplitAttributeDefinition:73] - Value Faculty/pt did not result in any values when split by regular

expression [a-zA-Z]*





On your test page it worked:
Test Results
Regular Expression

([a-zA-Z]*)?

as a Java string

"([a-zA-Z]*)?"

Replacement

groupCount()

1


Test

Target String

matches()

replaceFirst()

replaceAll()

lookingAt()

find()

group(0)

group(1)

1

Faculty/pt

No

/pt

/

Yes

Yes

Faculty

Faculty

next find()

Yes

next find()

Yes

pt

pt

next find()

Yes




How does attribute regexsplit work???

Does it return group(0)?

Leonard,



I don't have an exact solution but since that expression gets compiled into a Java regex object, you might try using one of the online Java regex sites. This is one I like:



http://www.regexplanet.com/advanced/java/index.html





It just gives an easy way to fine tune the expression quickly.
