public final class EndTag extends Tag
An end tag always has a type that is a subclass of EndTagType, meaning it
always starts with the characters '</'.
EndTag instances are obtained using one of the following methods:
Element.getEndTag()
Tag.getNextTag()
Tag.getPreviousTag()
Source.getPreviousEndTag(int pos)
Source.getPreviousEndTag(int pos, String name)
Source.getPreviousTag(int pos)
Source.getPreviousTag(int pos, TagType)
Source.getNextEndTag(int pos)
Source.getNextEndTag(int pos, String name)
Source.getNextEndTag(int pos, String name, EndTagType)
Source.getNextTag(int pos)
Source.getNextTag(int pos, TagType)
Source.getEnclosingTag(int pos)
Source.getEnclosingTag(int pos, TagType)
Source.getTagAt(int pos)
Segment.getAllTags()
Segment.getAllTags(TagType)
The Tag superclass defines the getName() method used to get the name of this end tag.
See also the XML 1.0 specification for end tags.

Returns null if this end tag is not properly matched to any start tag in the source document.
This method is much less efficient than the StartTag.getElement() method.
IMPLEMENTATION NOTE: The explanation for why this method is relatively inefficient lies in the fact that more than one
start tag type can have the same
corresponding end tag type, so it is not possible to know for certain
which type of start tag this end tag is matched to (see EndTagType.getCorrespondingStartTagType() for more explanation).
Because of this uncertainty, the implementation of this method must check every start tag preceding this end tag, calling its
StartTag.getElement() method to see whether it is terminated by this end tag.

This is equivalent to (EndTagType)getTagType().

Tag
The only requirement of an unregistered tag type is that it starts with
'<' and there is a closing '>' character
at some position after it in the source document.
The absence or presence of a '/' character after the initial '<' determines whether an
unregistered tag is respectively a
StartTag with a type of StartTagType.UNREGISTERED or an
EndTag with a type of EndTagType.UNREGISTERED.
There are no restrictions on the characters that might appear between these delimiters, including other '<'
characters. This may result in a '>' character that is identified as the closing delimiter of two
separate tags, one an unregistered tag, and the other a tag of any type that begins in the middle
of the unregistered tag. As explained below, unregistered tags are usually only found when specifically looking for them,
so it is up to the user to detect and deal with any such nonsensical results.
Unregistered tags are only returned by the Source.getTagAt(int pos) method,
named search methods, where the specified name
matches the first characters inside the tag, and by tag type search methods, where the
specified tagType is either StartTagType.UNREGISTERED or EndTagType.UNREGISTERED.
Open tag searches and other searches always ignore unregistered tags, although every discovery of an unregistered tag is logged by the parser.
The logic behind this design is that unregistered tag types are usually the result of a '<' character
in the text that was mistakenly left unencoded, or a less-than
operator inside a script, or some other occurrence which is of no interest to the user.
By returning unregistered tags in named and tag type
search methods, the library allows the user to specifically search for tags with a certain syntax that does not match any
existing TagType. This expediency feature avoids the need for the user to create a
custom tag type to define the syntax before searching for these tags.
By not returning unregistered tags in the less specific search methods, it is providing only the information that
most users are interested in.

The tidying of the tag is carried out as follows:
NORMAL end tag then any white space before the closing angle bracket is removed.
