Recognise Self Closing Tags with JavaScript via C++

Contents
[ ]

HTML can have a variety of tag formatting for empty tags like <td></td> or <td/>. Aspose.Cells for JavaScript via C++ supports both these formats now whereas earlier it was supporting only <td></td> like tags. This feature can be tested by converting the attached sample HTML file to an Excel file. The sample HTML file and output Excel file can be downloaded from the following links for testing.
