Hi,
I have a requirement to reference an element within the RFH2 header but the tag coming before it may change. For example.
it may be
InputRoot.MQRFH2.<something>.C
what kind of wildcard char do i need to put in to reference C.
Thanks,
Sailesh |

What is the position of this <something> element in your Tree? Is it the last element always? If so, you can use Anonymous field references like this,
| Code: |
InputRoot.MQRFH2.*[LAST].C

it will be in the same position.
for eample, it may be :
InputRoot.MQRFH2.A.C
or
InputRoot.MQRFH2.B.C
would a
InputRoot.MQRFH2.[*].C
work?
thanks |

What I ment was we need to know the position of this <something> element in MQRFH2 tree. For example, it could be the 3rd or last child of MQRFH2 tree? Can you print your ${Root} in a trace file and post the output here?

| i dont want to post the ${Root} but the <something> tag will always be at the same position, in this case the top level element after RFH2. basically we are putting an XML tree into the RFH2 and the elements after the top level tag will be the same and i can reference them explictly, but need a wildcard for the top level element. |

Looks like u will have only one top level element after MQRFH2. Use InputRoot.MQRFH2.*[LAST].C as suggested by kiran.

I guess
declare Ref REFERENCE TO InputRoot.MQRFH2.*[];
should work.
[2] refers to your 'c'. |

it will always be the third child of the Tree. either way i guess an anonymous field reference to either
InputRoot.MQRFH2.[3]*.C
or
InputRoot.MQRFH2.[LAST]*.C
will be the answer..
Thanks for the help |

And if you are running v5:
| Quote: |
For backward compatibility the LAST keyword is still supported, but its use is deprecated.
The LAST keyword has been replaced by the following arrow syntax, which allows both a direction of search and index to be specified:
Field [ > ] -- The first element, equivalent to [ 1 ]
Field [ > (a + b) * 2 ]
Field [ < ] -- The last element, equivalent to [ LAST ]
Field [ < 1 ] -- The last element, equivalent to [ LAST ]
Field [ < 2 ] -- The last but one element Field
[ < (a + b) / 3 ] |
Cheers,
