[EsiGate-users] Bug sur utilisation esi xpath

[Frederique A. <fre...@sm...>]

Bonjour, 

Lorsqu'on utilise esi:include : 
< esi:include src="$PROVIDER({ aggregated2 })/block.jsp" xpath="//html:div[@id='xpathfragment']" /> 

Si la page cible contient dans son tag HTML : xml:lang="fr" , ESIGate n'arrive pas à parser le document : 


org.w3c.dom.DOMException : NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.

Est ce que la modification suivante est envisageable dans la classe XpathRenderer : 


HtmlDocumentBuilder htmlDocumentBuilder = new HtmlDocumentBuilder(XmlViolationPolicy. ALLOW ); 
htmlDocumentBuilder.setNamePolicy(XmlViolationPolicy.ALTER_INFOSET); 

Les corrections proposées ont pour effet de transformer les attributs non reconnus dans le DOM, avec par exemple pour xml:lang : 

<html lang="fr" xmlU0003A0lang="fr" xmlns="http://www.w3.org/1999/xhtml"> 
Cette correction pourrait induire un effet de bord pour les syntaxes HTML5. 

Est ce que vous avez une meilleur solution ?
