Converting Javascript XML Object to String

I recently ran through a problem of XMLSerializer object. This is not working with IE. Fortunately IE support this simple method to convert an XML Objet to a String."XMLObject.xml".

What if you are unable to use any commercial tool available and still you want to design a pretty complex design, slice it, and convert it to html/css. How do I know this? I know this since once I ran in to this situation by myself. What I did first was to download Inkscape , which is a free vector graphic program. Creating a design in Inkscape is same as other vector graphic applications. But unfortunately there is no straight forward way of slicing the design and exporting. This is what I did as a workaround. I simply add a new layer to the project and named it as “slicing”. I made sure to keep the “slicing” layer above from the rest of the layers and locked all the other layers below it. I drew a rectangle surrounding the area I wanted to export. If the rectangle has stroke or fill it was critical to disable them since I wanted to export onl
