How to use the less than < character in labelling expression?

[VaL]

Hi,

I have a labelling expression that need to input the '<' character.

I also have some text formatting like

a="<CLR red = '255'> <SUP>1</SUP></CLR>"
if [Qualifier] =='<':
b=' \x3c'
return [PointID]+b+[maxres]+a

and adding < simply break everything.

If I dont use the formatting, < can be added.

So how do I escape it?

The Text Formatting Tags help documentation says to use &lt; in place of an angle bracket and &amp; in place of an ampersand when using text formatting tags. Your formula becomes:

def FindLabel ( [Qualifier], [PointID], [maxres] ):
    a="<CLR red = '255'> <SUP>1</SUP></CLR>"
    if [Qualifier] =='<':
        b=' &lt;'
        return [PointID] + b + [maxres] + a
