RE: [cam] Variable Names

Title: Message

Further investigation shows the following would be possible but different if we used native xpath to resolve these conditions:

 

    equal  would be come => $variable = 'testValue'

    NOTequal(value,'value') => not(value1,'value')

    greaterthan(v,v) => value > value

    lessthan(v,v) => value < value or value &lt; value

    greaterthanEQ => value >= value

    lessthanEQ => value <= value or value &lt;= value

    begins => starts-with(value,value)

    ends => ends-with(value,value)

    contains => as stated

 

    We would also get for free string-length(), count() etc...  plus we get someone else to do the exception management.

 

    I personally am all for not reinventing things.  The problem would be lookup() and member() but looking at the code it should be possible to extend the function sets supported by Jaxen.  There is a minor bug in jaxen and this is that the id() function does not seem to work.  Minor problem.

David,
        I am using JDOM and it has a link to the xpath tools from jaxen.  One of the things you can do is setVariables.  If then we had our variable in $varName format we could simply leave the paths alone set the variables based on the as:Declaration sections.

        This would make life easier.

        I am going to run with this.
