[TYPO3-templavoila] Section Container Index

[lee perry]

hello,

i built in a FCE a SECTION with a CONTAINER and now i need the index of 
every NEW CONTAINER by using this FCE.
i can find in the XML in the tt_content tablefield 'tx_templavoila_flex' 
for example 3 NEW CONTAINER:

<section index="1">...</section>
<section index="2">...</section>
<section index="3">...</section>

How can i get the information of this index in the typoscript in the 
datastructure of this FCE, maybe for a different handling of every 
second CONTAINER?

any idea?

thanx and greetings,
lee
