public final class AttributeSelectionMarkingMarkupHandler extends AbstractChainedMarkupHandler
Implementation of the IMarkupHandler that
adds an attribute (with a user-specified name) to all elements that match one or more selectors,
as determined by a BlockSelectorMarkupHandler or
NodeSelectorMarkupHandler handler.
So for example, given an instance of this handler configured to use "selectors" as its attribute name and an <img href="logo.png"> tag that matches both selectors "//img" and "div/img", this handler would transform such tag in: <img href="logo.png" selectors="[//img,div/img]">
| Constructor and Description |

AttributeSelectionMarkingMarkupHandler(String selectorAttributeName,
IMarkupHandler handler)
Build a new instance of this class, specifying the name of the attribute to be added to the matching elements
and also the handler all events should be delegated to.

IMarkupHandler
Sets the ParseSelection object that represents the different levels of
selectors (if any) that are currently active for the fired events.
This method is always called by the parser before calling any other event handling method.
Note that this method can be safely ignored by most implementations, as there are very few scenarios in which this kind of interaction would be consisdered relevant.

Three [offset, len] pairs are provided for three partitions (name, operator, valueContent and valueOuter):

Artifacts are reported using the document buffer directly, and this buffer should not be considered to be immutable, so reported structures should be copied if they need to be stored (either by copying len chars from the buffer char[] starting in offset or by creating a String from it using the same specification).
Implementations of this handler should never modify the document buffer.
