Parsing HTML Tables

Applies to TestComplete 14.30, last modified on November 21, 2019

TestComplete provides scripting access to web page elements as well as to their attributes, methods and events. You can use this functionality to obtain data from tables displayed on the web page under test.

A table is an HTML TABLE element with special sub-elements for the table’s header, footer and body. These sub-elements contain rows and cells.

To retrieve data from a table, you can use the “native” properties of the DOM table object. Alternatively, if you use the Tree web testing model, you can work with HTML tables using the features provided by this model.

Using Internal Properties

To retrieve data from a table, you can use the rows and cells properties of the table object (this is an object defined by the Document Object Model). The cells property belongs both to the table and to the row objects. The table’s property provides access to all cells of the table. The row’s property provides access to values displayed in the row’s cells.

The code below goes through the rows and cells of a table and posts the cell contents to the log. The sample routine works with the www.w3schools.com/html/tryit.asp?filename=tryhtml_table_intro web page displaying a sample table.

}

Note that the rows property of the table object provides access to all rows of the table, including the rows displayed in the table’s header and footer. To only process cells of the table body, you obtain the objects corresponding to the TBODY elements (note that a table can contain several TBODY elements) and then go through the rows and cells of each TBODY.

The following code demonstrates how you can do this.

  var table = page.FindChild("tagName", "table", 10);
  if (table.Exists)
    // Parses the table
    ParseTable(table);
  else
    Log.Warning("The table is not found.");

}

function ParseTable(ATable)
{

  Log.AppendFolder("Table");

  // Parses the TBODY elements

Using Properties Provided by the Tree Model

If the Tree model is used in the current project, TestComplete reflects the actual hierarchy of objects on the HTML page under test in the web object tree. In this model, a table object has child Cell objects that correspond to the table cells. Cells are addressed using their zero-based row and column indexes. For instance, the Cell(2, 1) notation corresponds to the second cell in the third row. Besides that, TestComplete extends the functionality of the DOM table object with the RowCount and ColumnCount(RowIndex) properties. The RowCount property returns the number of table rows, and the ColumnCount property lets you get the number of cells in the row with the RowIndex index (in general, different table rows can contain a different number of cells). You can use these properties for iterating through the table cells.

Below is an example that processes a table using the described approach.

Note, however, that the table’s child Cell objects provide access to all table cells, including those displayed in the table header and footer. If you only need to process the table body cells, use the approach described in the previous section.

You can call the described script routines from keyword tests. To do this, use the Run Script Routine operation. Prepare the script code and then add the operation to your keyword test. TestComplete will display the Select Test dialog where you will be able to choose the desired routine.
