macOS Extracting text with applescript

[Swarowsky]

Hello.

I'm relatively new to applescript and I'm having some problems with the following:

I have a text file with text like this:

"<ipp-com:TotalEfectivosEquivalentesFinalPeriodo decimals="0" contextRef="S22008_A-41002288_dpai" unitRef="euro">537691000</ipp-com:TotalEfectivosEquivalentesFinalPeriodo>
</ipp-gen:EstadoFlujosEfectivoIndividual>
<ipp-gen:BalanceConsolidado>
<ipp-gen:ActivoNoCorrienteNiif decimals="0" contextRef="S22009_A-41002288_icc" unitRef="euro">7993707000</ipp-gen:ActivoNoCorrienteNiif>
<ipp-gen:ActivoNoCorrienteNiif decimals="0" contextRef="S22008_A-41002288_ipac" unitRef="euro">5107430000</ipp-gen:ActivoNoCorrienteNiif>"


and I'm trying to write an applescript that will copy the text between the ">" "<" characters, when the line begins a specific way (for example, when the line begins with "<ipp-gen:ActivoNoCorrienteNiif decimals="0" contextRef="S22009".)

I've been reading and experimenting with applescript for some time, but I'm strugggling with this. Any pointers or help would be greatly appreciated.

Thanks!
