Chapter Eleven — SGML Functions (continued)

SGMLFindElement Function

Overview

The SGMLFindElement function parses forward until the specific element is found.

Syntax/Parameters

Syntax

string = SGMLFindElement ( handle hSGML, TOKEN token | string element, [int x, int y] );

Parameters

hSGML

A handle to an SGML object.

token

An optional TOKEN (dword) for an HTML token or other element as defined in the DTD. Or,

element

A string version of the HTML or other element. One of the token or element must be provided.

x

An optional int value specifying the zero-based X position to parse from. The position is native. When provided, the Y position must also be provided. If omitted, the function parses from the current position.

y

An optional int value specifying the zero-based Y position to parse from. The X position must be provided with this parameter.

Return Value

A string containing the tag’s text, an empty string on error. Use the GetLastError function to retrieve an error code.

Remarks

The SGMLFindElement skips all tags, spaces, character entities and PCDATA to get to the specified element. If the end of data is reached prior to a tag, an empty string is returned and ERROR_EOD will be placed in the last error buffer.

The current position, properties and other characteristic are made available through various ‘get’ functions.

Since SGMLFindElement only reads tags, the tag will be parsed into its components.
