RES: Extracting Tables from PowerPoint

[Gerson]

Hi,

Using your example below, I was able to identify the number of cells
correctly, but the text is not coming, when I ask the length of the array of
RichTextRuns from the text boxes, it returns 0 (Zero).

Do you know why this can be happening, and a possible solution?

Thnx again,


Gerson Albuquerque

Hi,

A table in PowerPoint is a group of shapes.
It HSLF API it is represented by a org.apache.poi.hslf.model.ShapeGroup
class.
Typically a table consists of TextBox and Line objects which represent
text runs and borders.

Below is sample code how to iterate over table cells:

 Slide slide = ...;
 Shape[] sh = slide.getShapes();
 for (int i = 0; i < sh.length; i++) {
   if (sh[i] instanceof ShapeGroup){ //got a table
     ShapeGroup table = (ShapeGroup)sh[i];
     Shape[] ch = table.getShapes();
     for (int j=0; j<ch.length; j++){
       if (ch[j] instanceof TextBox){
         TextBox txt = (TextBox)ch[j];
         String text = txt.getText(); //text in a table cell
       }
     }
   }
 }

Creating new tables is not yet supported. It's clear how to implement
it, just need time.
