Structured Data and XML Documents

Work with structured data and Extensible Markup Language documents

Read and write structured data in XML files. Develop advanced applications that create, read, write, transform, or query XML documents using the MATLAB^® API for XML Processing (MAXP). To use MAXP, you need to be familiar with XML, DOM, XSLT, XPath, and the associated W3C standards.
