Review on PDFTron by Rob Kerr

Our software development group has built several applications with their SDK. As an industry we are starting to use XML much more frequently. We use XODO for extracting XML from our PDF documents and have been happy with the results. However, recently we have encountered an issue where our PDF documents are being rejected because the "XML content is too large" error message. This happens when the size of the xml is larger than 100k bytes. This is happening intermittently and is affecting our application. After reviewing the code and seeing that there is no way to change the size limit of the xml the only option left was to move to another SDK. Unfortunately, we decided to move away from XODO and went back to PDFTron. Our new applications still require us to extract xml from PDF documents and although it works fine for small documents it is causing issues when we have a large document. The problem is that PDFTron requires that you specify a maximum byte size before they will accept your document.
