Bug 76703 – [MicroData] Compilation error while building Webkit with --microdata.

• Component: DOM
• Status: RESOLVED FIXED

[Arko Saha]

MICRODATA enabled build is now failing with below errors :

1. Due to changes http://trac.webkit.org/changeset/102834. MicroDataItemList should be derived from DynamicSubtreeNodeList instead of DynamicNodeList.

2. Due to changes in http://trac.webkit.org/changeset/103883. The signature of 'WebCore::HTMLCollection::HTMLCollection()' is changed. Now it takes Node* as first parameter, hence resulting the error. 
Source/WebCore/html/HTMLPropertiesCollection.cpp: In constructor ‘WebCore::HTMLPropertiesCollection::HTMLPropertiesCollection(WTF::PassRefPtr<WebCore::Node>)’:
Source/WebCore/html/HTMLPropertiesCollection.cpp:59:46: error: no matching function for call to ‘WebCore::HTMLCollection::HTMLCollection(WTF::PassRefPtr<WebCore::Node>&, WebCore::CollectionType)’
