How to visualize my xml data?

Question

Hi everyone,

I'm trying to open a xml file with yEd to visualise data in hirachical binary tree structure. First, when I import my xml file, it asks XSL file that I don't have! Secondly the nodes in my tree must have either 2 children or no child (Binary tree). 

Here I bring my xml file :

<?xml version="1.0" encoding="UTF-8"?>

Could anyone help me to visualize my binary tree?

Thank you

Answer 1

First, the data you posted is not XML. There are lots of '-<' character sequences in your sample which are not valid in XML.

Second, even after sanitizing your sample (i.e. replacing '-<' with '<'), your data does not describe a binary tree. E.g. element <SpatialDecomposition> has 15 child elements.

Third, although yEd asks for a custom XSLT stylesheet when using the "XML+XSL" import, it does provide a couple of predefined stylesheets as well. These predefined stylesheets are available through the "XSL File for" drop down list. E.g. importing a sanitized version of your sample with the predefined stylesheet "XML-Tree" results in this diagram.
