Extract CSS property

Selenium Nodes for KNIME version 4.0.2.201908091817 by seleniumnodes.com

This node extracts a CSS property from a WebElement. For the specified CSS property name, the property values are appended as string column to the input table. In case, a CSS property is not present, a missing value cell is appended.

Note: “Shorthand” CSS properties such as background, font, border, etc. are usually not supported, instead you must use the explicit longhand property names, such as background-color, font-size, etc.

Color values are returned as RGBA strings, e.g. for a color property green Selenium will return rgba(0, 255, 0, 1).

Options

Input: Input column which provides the WebElement(s)
Remove input column: Removes the input column from the result table
CSS value name: The name of the CSS property to extract

Input Ports

: Table with a column providing WebElements to extract

Output Ports

: Table with appended column holding the specified property value
