From the help file in StringTools - Split:


There is no information about how this is done, though.

Accessing components from library...

procedure library

Apparently it isn't possible to access components in a workbook from procedures from a library.

Just wanted to know if that is correct, or if I am missing something here.

E.g. this procedures should delete contents of TextAreas with endings defined in a list of variables. Works nicely in the workbook, but when putting the procedure in a library, it apparently doesn't work anymore.

XML - colon in strings...

Apparently a colon within a string causes some issues when generating a XMLElement.

Didn't find anything in Maple Help about that though.

with(XMLTools)

dummy := "NS-EN 1995-1-1, part 1-1, Section 6"

"NS-EN 1995-1-1, part 1-1, Section 6"

 (1)

XMLElement(dummy)

_XML_Element(_XML_ElementType("NS-EN 1995-1-1, part 1-1, Section 6"), [], [])

 (2)

dummy1 := "NS-EN 1995-1-1, part 1-1, Section 6: Ultimate"

"NS-EN 1995-1-1, part 1-1, Section 6: Ultimate"

 (3)

XMLElement(dummy1)

Error, (in XMLTools:-XMLElement) element tag name `NS-EN 1995-1-1, part 1-1, Section 6: Ultimate' contains the namespace prefix `NS-EN 1995-1-1, part 1-1, Section 6', but there is no `xmlns' attribute

Convert variable name to string...

Is there any way to convert a variable name to a string?

In that example, the content of the variable is converted to string, not the name of the variable.


 

a := 2

2

 (1)

convert(a, string)

"2"

 (2)

NULL
