Syntax

Copy

typedef enum {

CONTEXT_TYPE_None = 0,

CONTEXT_TYPE_Text = 1,

CONTEXT_TYPE_EnterScope =
2

CONTEXT_TYPE_ExitScope =
3,

CONTEXT_TYPE_NoScope = 4

} MARKUP_CONTEXT_TYPE;

Constants

CONTEXT_TYPE_None

There is no markup content next to the markup pointer in the specified direction.

CONTEXT_TYPE_Text

The markup content next to the markup pointer in the specified direction is text.

CONTEXT_TYPE_EnterScope

An element's opening tag is next to the markup pointer in the specified direction.

/ / Here CONTEXT_TYPE_EnterScope
is markup pointer
neighbor elements in the specified direction
of opening tag,
that <xx> (</
xx>) element,
but that is not the
case, CONTEXT_TYPE_EnterScope
represented in a given direction,
into <xx> ...
</ xx>
element or leave this
element.

Example: <xx>
| ... </
xx> (red
vertical line represents
markup pointer) to test if
the left
(Left function that is
called):

HRESULT Left (BOOL fMove, MARKUP_CONTEXT_TYPE * pContext, IHTMLElement ** ppElement, long * pcch, OLECHAR * pchText);

Get to parameter
pContext is CONTEXT_TYPE_ExitScope
a Left is
to promote markup
the Pointer to leave
<xx> ... </
xx> element.
But

Markup pointer <xx> ...
</ xx>
| this position,
then the Left function parameters
pContext is CONTEXT_TYPE_EnterScope.

Conclusion: IMarkupPointer
:: Right /
Left function returns the
pContext determined by their
leave or enter
the element node,
rather than the current direction of movement of
the neighbor is
opening or closing
tag.
