Saxon XSLT and XQuery Processor

Hello,

Node type 5 is an "entity reference node". Saxon can't handle a DOM
containing entity reference nodes, all the entities must have been fully
expanded.=0D

The entity reference nodes are there because you have set:

>    documentBuilderFactory.setAttribute(
>         "http://apache.org/xml/features/dom/create-entity-ref-nodes",
>         Boolean.TRUE);


Do you really need them for your processing?=0D

--> I do need the entity references in my processing and want to make it in=
 one shot. What I mean by this is that I can't parse my document once, do=
 my processing with SAXON then serialize it again with the modifications=
 and re-parse this serialized file (with entities references) to do another=
 processing.

I have looked at the given stack trace and modified SAXON code=
 ('makeWrapper' method in the net.sf.saxon.dom.NodeWrapper class) by adding=
 the following lines :

case Node.ENTITY_REFERENCE_NODE:
          wrapper =3D new NodeWrapper(node, parent, index);
          wrapper.nodeKind =3D Type.COMMENT;
break;


It seems to work on my example but I was wondering if my modifications were=
 valid or not and if any problem can occur whit this modification.

Thanks in advance,
J=E9r=F4me.

The answer is that it will almost certainly break something, but I can't tell exactly what without a considerable amount of testing. It will probably break any stylesheet that accesses real comments, because a DOM entity reference node has a null nodeValue, and the code for processing comments assumes a non-null nodeValue. It's very often the case with things like this that you need to create 50 test cases to determine whether a three-line source change is viable: and in the case of DOM code, you need to run these tests against three different DOM implementations before you can be sure it's OK. At the very least, your change will create a data model that is an incorrect representation of the source document: the text or element nodes that are children of the entity reference will not be visible as part of the tree, and will not be copied by an xsl:copy operation. So even if the patch works for you, it's certainly not a general solution. If this facility is sufficiently important to you that your company would be interested in sponsoring the development of a solution, please contact me off-list. Michael Kay http://www.saxonica.com/
