ASN.1

• Preprocessed with ASN1C

XSL generator

• Takes Xpath formats as input

• Generates XSL file– XSL is used for XML to CSV conversion using

XSLT

• Returns string status

132009-01-15

Basic idea

• Linearize XML file– Root nodes at same level are represented as

one (or more rows) in CSV file– Root nodes that are not in the same level are

left empty

142009-01-15

Example XML<?xml version="1.0" encoding="utf-8"?>

<C T="[APPLICATION 1]">

<P T="[APPLICATION 41]">02</P>

<P T="[APPLICATION 38]">HRVVI</P>

<P T="[APPLICATION 45]">+0200</P>

<C T="[APPLICATION 2]">

<C T="[APPLICATION 4]">

<P T="[APPLICATION 34]">29340011</P>

<P T="[APPLICATION 19]">00</P>

</C>

<C T="[APPLICATION 4]">

<P T="[APPLICATION 34]"> 2934 </P>

<P T="[APPLICATION 19]">00</P>

<C T="[APPLICATION 4]">

C[@T='[APPLICATION 1]' and @name='Nrtrde']/P[@T='[APPLICATION 38]' and @type='OCTET STRING']

C[@T='[APPLICATION 1]']/C[@T='[APPLICATION 2]']/C[@T='[APPLICATION 4] ' and @name='mtc']/P[@T='[APPLICATION 34]' and @type='OCTET STRING']
