How can I sort lists which have tables as entries, and decide upon which entry the sort should be based.

In the attached example each entry in the list has the values material, name and type.

• How would I sort the list based on the material name for example?
• Are there any better methods to define and store the data?

Just curious about an output in an if statement.

Why do I need to use Print() in an if statement, when I don't need it otherwise? Why doesn't "hei" show in the output of the attached example?

Here's part of the XML file.

How can I convert this string value ("10.*Units:-Unit(m)") to a number attached the defined units?

Why do I get an error when using this:/// during readin of a xml attachment in Maple workbook?
