Since this is only used in tests, lets put it in Internals.

+{
+    ASSERT(elementData);
+
+    RefPtr<HTMLCollection> metaElements = getElementsByTagName(HTMLNames::metaTag.localName());

[esprehn, 2014/06/13 08:47:06]

We don't normally allow code like this in core/, except in Internals.

Replaced getElementsByTagName with Traversal<HTMLMetaElement>.

+    for (unsigned i = 0; i < length; ++i) {
+        ASSERT(metaElements->item(i)->isHTMLElement());

+        Vector<String> tokens;
+        String(metaElement->content().impl()).split(';', tokens);

+
+        RefPtr<NodeList> nodeList = querySelectorAll(AtomicString(tokens[0]), exceptionState);

+            Node* node = nodeList->item(nodeIdx);
+            markup = markup + createStyledMarkupForNavigationTransition(node);
+        }
