Метод Описание
AttributeEncode ( string text, bool alwaysQuote, string &quoteChar ) : string

HtmlEncode a string, except for double-quotes, so it can be enclosed in single-quotes.
ChildrenAllowed ( string nodeName ) : bool

Test whether this element can have children.
ChildrenAllowed ( ushort tokenId ) : bool

Test whether this element may have children.
HasValueProperty ( string nodeName ) : bool

Test if a node type has a VALUE property.
HasValueProperty ( ushort nodeNameToken ) : bool

Test if a node type has a VALUE property.
HtmlChildrenNotAllowed ( string nodeName ) : bool

This type does not allow HTML children. Some of these types may allow text but not HTML.
HtmlChildrenNotAllowed ( ushort nodeId ) : bool

This type does not allow HTML children. Some of these types may allow text but not HTML.
IsBlock ( string nodeName ) : bool

Test whether the node is a block-type element
IsBlock ( ushort tokenId ) : bool

Test whether the node is a block-type element.
IsBoolean ( string propertyName ) : bool

Test whether the attribute is a boolean type.
IsBoolean ( ushort tokenId ) : bool

Test whether the attribute is a boolean type.
IsCaseInsensitiveValues ( string attributeName ) : bool

Test whether an attribute has case-insensitive values (for selection purposes)
IsCaseInsensitiveValues ( ushort attributeToken ) : bool

Test whether an attribute has case-insensitive values (for selection purposes)
IsFormInputControl ( string nodeName ) : bool

Test if the node name is a form input control.
IsFormInputControl ( ushort nodeNameToken ) : bool

Test if the node name is a form input control
SpecialTagAction ( string tag, string newTag, bool isDocument = true ) : ushort

For testing only - the production code never uses this version.
SpecialTagAction ( ushort parentTagId, ushort newTagId ) : ushort

Return the type of action that should be performed given a tag, and a new tag found as a child of that tag.

Some tags have inner HTML but are often not closed properly. There are two possible situations. A tag may not have a nested instance of itself, and therefore any recurrence of that tag implies the previous one is closed. Other tag closings are simply optional, but are not repeater tags (e.g. body, html). These should be handled automatically by the logic that bubbles any closing tag to its parent if it doesn't match the current tag. The exception is <head> which technically does not require a close, but we would not expect to find another close tag Complete list of optional closing tags: HTML, HEAD, BODY, P, DT, DD, LI, OPTION, THEAD, TH, TBODY, TR, TD, TFOOT, COLGROUP body, html will be closed automatically at the end of parsing and are also not required.

SpecialTagActionForDocument ( ushort parentTagId, ushort newTagId ) : ushort

Determine a course of action given a new tag, its parent, and whether or not to treat this as a document. Return 1 to close, 0 to do nothing, or an ID to generate.
TokenName ( ushort tokenId ) : string

Return a token name for an ID.
Tokenize ( string name ) : ushort

Return a token for a name
TokenizeCaseSensitive ( string name ) : ushort

Return a token for a name, adding to the index if it doesn't exist. When indexing tags and attributes, TokenID(tokenName) should be used.

Приватные методы

Метод Описание
HtmlData ( ) : System
PopulateTokenHashset ( IEnumerable tokens ) : HashSet
TokenizeImpl ( string tokenName ) : ushort

Return a token ID for a name, adding to the index if it doesn't exist. When indexing tags and attributes, ignoreCase should be used.
Touch ( ) : void
setBit ( IEnumerable tokens, TokenProperties bit ) : void

For each value in "tokens" (ignoring case) sets the specified bit in the reference table.
setBit ( IEnumerable tokens, TokenProperties bit ) : void

For each value in "tokens" sets the specified bit in the reference table.
setBit ( ushort token, TokenProperties bit ) : void

Set the specified bit in the reference table for "token".
