[Translet-general] Re: Query about XPATH

[Karthikeyan M. <km...@li...>]

The solution depends on the use case. I used to use regular expressions 
in combination with the xpath expressions to handle form posts. 
Supposing that you are getting the information as:
<formfieldname> => <field-value>
firstname1 => x1
firstname2 => x2
lastname1 => y1
lastname2 => y2

I had a regular expression  of the form
firstname(\d+)
and get the number from it and use it in my

"/user/person["+<matched-value>>+"]/firstname"

If you have a different use case, then you can use a counter to set the 
number correct. The translet itself is quite stateless. You need to give 
it enough information to figure it out that the following sequence all 
belongs to the same person element:
"/user/person/firstname"
"/user/person/lastname"
"/user/person/ssn"

Alternatively, if you getting data bursts, you can have two DOMs and 
create nodes in the one dom and detach and attach it to the other dom 
after each pass. In that case you need to have only one set of XPaths 
without any numbers in it.
hope that helps,
