Z 3.4.6, preprocessing, regex

[Anth(0)ny]

Hello!

I have a problem with item's data and preprocessing regex.

Main item: telnet agent with 2 step-by-step commands. 2 entered requests return formatted multistring xml (text) with few garbage strings (echo of entered commands).

Dependent items: gets data from main item via xpath request
Data: extract from main item - various types (text, numeric, etc)

At request's result I get 2 similar xml blocks of data and i need to ignore the 1st ocurrence (1st block) and place data to item from 2nd only, because 1st is useless and MUST be ignored.

Block's tags:

<RESPONSE VERSION="L100"> ... </RESPONSE>

My problem: i always get empty data at main item if i try to use regexp preprocessing. Main item is supported, but data always is empty.

Can anybody help with CORRECT preprocessing regexp, please?

I try to use this schema:

1. Main item get raw text data with xml blocks and try to extract a 2nd ocurrence with this regexp:

(?:<R((?:.*?\r?\n?)*)E>)
Output to get 2nd ocurrence: \2

2. All dependent items extract data from main item via xpath requests, like this:

/RESPONSE[@VERSION="L100"]/OBJECT[1]//PROPERTY[@name="virtual-disk-serial"]/text()

/RESPONSE[@VERSION="L100"]/OBJECT[1]//PROPERTY[@name="health-numeric"]/text()

etc

Full responce xml code and current experimental regex is here: https://regex101.com/r/I2ehOc/3

Thank you.
