XML Marker is an XML Editor that uses a synchronized table-tree-and-text display to show you both the hierarchal and the tabular nature of your XML data.

It automatically produces a tabular display of any selected tag by collecting repeating attribute and tag names and then arranging them into columns. The result is a clutter-free and informative tabular display.

The implementation is very efficient in memory and CPU resources so you can quickly navigate through very large XML files - up to hundreds of megabytes and even gigabytes of XML data on a standard personal computer.

XML Marker is the perfect tool to work with plain-text debugging output and log files. You can dramatically increase their usefulness by modifying your programs to produce them in XML format. After that, you can use the graphical features of XML Marker to spot hidden trends and to solve your bugs faster.

More features include table sorting, syntax-highlighting editor, automatic indentation/pretty-printing of exiting code, drill down and as-you-type syntax checking.
