David Bertoni commented on XALANC-609:
--------------------------------------
It's amazing we haven't hit this bug before, since it's been in the processor
for years.
I think the best fix is to add a static instance of an empty list, then convert
the assert to an actual if test:
#if defined(XALAN_OLD_STYLE_CASTS)
if (DOMServices::isNamespaceDeclaration((const XalanAttr&)theNode) ==
true)
#else
if ((DOMServices::isNamespaceDeclaration(static_cast<const
XalanAttr&>(theNode)) == true)
#endif
{
return &s_emptyTemplateList;
}
We'll also have to filter out the namespace nodes in
ElemTemplateElement::findTemplateToTransformChild():
case XalanNode::CDATA_SECTION_NODE:
case XalanNode::TEXT_NODE:
theTemplate =
getStylesheet().getStylesheetRoot().getDefaultTextRule();
break;
case XalanNode::ATTRIBUTE_NODE:
if (DOMServices::isNamespaceDeclaration(static_cast<const
XalanAttr&>(*child)) == false)
{
theTemplate =
getStylesheet().getStylesheetRoot().getDefaultTextRule();
}
break;
This is a potential performance issue, and points out why we shouldn't be using
attributes to represent namespace nodes. It's just another one of the many
issues with representing the source tree as an instance of the DOM.
