1e Even the modify XML file look like what u see below, still give me 5 for the lengh.There is still whitespace text between the elements.
If you don't want to see the Text elements, you should use the following:
<aaron2 lettres="DEORSU"><solution>
<mot3 mot="DOX"/>
<mot4 mot="DUVF"/>
</solution><dictionnaire>
<mot3 mot="DES"/>
<mot4 mot="DESF"/>
</dictionnaire></aaron2>
2e It return length = 0 for line u see below
NodeList children = aronDoc.getDocumentElement().getElementsByTagName(aronDoc.getDocumentElement().getNodeName());
That is because you are asking for the elements from the document-element which have the same name as the document element.
Your code is equivalent to:
NodeList children = aronDoc.getDocumentElement().getElementsByTagName("aaron2");Instead you probably want the following:
NodeList children = aronDoc.getDocumentElement().getElementsByTagName("solution");
