with the existing transformer, the index has this structure:
field value
content coco coco2
(In fact, in the real situation, the index is empty because the transformer
index the content if this content is into the <body> tags, normal for a
HTML indexer, but not for a XML indexer, that why i say that my transformer
can index XML data (with a XSL transformation) and not realy the existing
indexer)

I see. So this is why you say your version is more "low-level", with fields
that map directly to the Lucene index.

OK, so with the existing transformer you could directly index this document:
<tag1>
<tag2>coco</tag2>
<tag3>coco2</tag3>
</tag1>
You would get:
field value
tag1 coco coco2
tag2 coco
tag3 coco2
With your transformer you would need to transform it first into something
like:
<field name="tag1">coco coco2</field>
<field name="tag2">coco</field>
<field name="tag3">coco2</field>
Is that right?
