2.1.1 [DOMLevel2Traversal:2000] Section 1.2, Formal Interface Definition
V0001:
-
filter of type NodeFilter, readonly The NodeFilter used to screen nodes.
IE9 Mode, IE10 Mode, IE11 Mode, and EdgeHTML Mode (All Versions)
The filter property returns a function pointer to the NodeFilter callback.
V0002:
-
acceptNode Test whether a specified node is visible in the logical view of a TreeWalker or NodeIterator. This function will be called by the implementation of TreeWalker and NodeIterator; it is not normally called directly from user code. (Though you could do so if you wanted to use the same filter to guide your own application logic.) Parameters n of type Node The node to check to see if it passes the filter or not. Return Value short a constant to determine whether the node is accepted, rejected, or skipped, as defined above. No Exceptions
IE9 Mode, IE10 Mode, IE11 Mode, and EdgeHTML Mode (All Versions)
The acceptNode method can return a hexadecimal string of the form "0x1", which indicates FILTER_ACCEPT behavior. However, in this case, the string is not converted into the FILTER_ACCEPT constant value.
V0007:
-
createNodeIterator Create a new NodeIterator over the subtree rooted at the specified node. Parameters root of type Node The node which will be iterated together with its children. The iterator is initially positioned just before this node. The whatToShow flags and the filter, if any, are not considered when setting this position. The root must not be null. whatToShow of type unsigned long This flag specifies which node types may appear in the logical view of the tree presented by the iterator. See the description of NodeFilter for the set of possible SHOW_ values. These flags can be combined using OR. filter of type NodeFilter The NodeFilter to be used with this TreeWalker, or null to indicate no filter. entityReferenceExpansion of type boolean The value of this flag determines whether entity reference nodes are expanded. Return Value NodeIterator The newly created NodeIterator. Exceptions DOMException NOT_SUPPORTED_ERR: Raised if the specified root is null.
IE9 Mode, IE10 Mode, and IE11 Mode (All Versions)
The NodeIterator returned by the createNodeIterator
method has the whatToShow property value set as -1
instead of the expected value of 0xFFFFFFFF.
