PDF documents are widely used but the extraction and the manipulation and of their structured content is not an easy task. It requires sophisticated pre-processing and reverse engineering techniques to get such achievements. In this paper, we present an improvement of XED in order to handle unresolved issues related to the analysis of Arabic documents. A set of rules were proposed and implemented to enhance the extraction of Arabic content, by taking care of the different Arabic fonts, through mapping the un-interpreted Unicode values to the other interpreted sets as well as applying a reverse algorithm whenever needed. We finally expose concrete evaluations for the improvement of XED.
