thank's for your help.
for 2 of my ebooks, the verification is ok (no problem at all)
for one, this message : index_split_003.html (ligne : 9) which is :
<body class="calibre">
???
and for the line/column information, I found no problem in the code...
I join a file with his message :
the message :
index_split_005.html:10, 282: Error while parsing file 'text not allowed here; expected element "address", "blockquote", "del", "div", "dl", "h1", "h2", "h3", "h4", "h5", "h6", "hr", "ins", "noscript", "ns:svg", "ol", "p", "pre", "script", "table" or "ul" (with xmlns:ns="http://www.w3.org/2000/svg")'.
