Chapter Eleven — SGML Functions (continued)

HTMLGetContext Function

Overview

The HTMLGetContext scans an HTML file and returns the context stack, as it stands, from the last scan.

Syntax/Parameters

Syntax

string [][] = HTMLGetContext ( handle hObject );

Parameters

hObject

A handle to an HTML Context, SGML, Mapped Text or Edit Object.

Return Value

A string table containing a row entry for every element in the element stack or an empty array on failure. Use the GetLastError function to retrieve a formatted error code.

Remarks

The function will dump the HTML element stack, as is standard from the end of the last scan.

A table with the following column keys are returned:

  Key Name   Description  
  element_token   Hexadecimal version of the element token.  
  element   String version of the element, as translated by the DTD.  
  s_x   Decimal zero-based x position of the start of the tag.  
  s_y   Decimal zero-based y position of the start of the tag.  
  e_x   Decimal zero-based x position of the end of the tag.  
  e_y   Decimal zero-based y position of the end of the tag.  
  e_type   Hexadecimal version of the bitwise element type.  
  d_cnt   Descendant Count.  
  s_pos   Zero-based sibling position.  
  i_no   Decimal value of the list item number.  
  l_type   Hexadecimal version of the list type.  
  t_no   Decimal value of the serial table number.  
  t_tl   Decimal value of the table level. If zero, not in a table.  
  t_r_no   Decimal value of the row number.  
  t_c_no   Decimal value of the column number.  
  t_c_pos   Decimal value of the column position (accounting for spans).  
  t_c_span   Decimal value of the column span value.  
  c_i1   Decimal value of the caller integer.  
  c_i2   Decimal value of the caller integer.  
  c_d1   Hexadecimal version of the caller dword.  
  c_d2   Hexadecimal version of the caller dword.  

 

A point of interest must be set for the scan in order to read the stacked elements at the position. The scan must have a stop position. If the overall file is not balanced and a stop position not set, any extra open tags will show up at the end point context.

The e_type parameter is a complex bitwise value with the following defined bits:
