RE: Pattern Matching a sting value

In this specific example I would think you could use

substring-before(
    substring-after($x, 'font-family'),
    ";")

But of course what you really need is the regex handling offered by XSLT
2.0.

How in XSLT 1.0 do you interogate a specific portion of a string?
   



 

$stg = "font:...;font-family:Arial;color:#FFFFF;...."

I am only interested in the portion of this string that
contains Arial.
   


Not sure what interested means, if you want to test for the 
existance 
use the boolean contains() function;

    contains($stg,'Arial') would return true

Otherwise use the following string based functions

    string substring-before(string, string)
    string substring-after(string, string)
    string substring(string, number, number?)
    string concat(string, string, string*)
    number string-length(string?)

You might need these as well;

    string normalize-space(string?)
    string translate(string, string, string)

Check out here for specific techniques;

Otherwise if you want something with regular expressions or more 
advanced string handling like replacing text check out www.exslt.org.

Jim,

specifically I have a attribute that contains many values 
that I have to 
break apart and set to individual attribute values so
a string that contains 
"color:#FFFFF;font-family:Arial;font-weight:bold;" I would need to 
select only the value begining after the : in font-family and ending 
with;before font-weight.

Do any of the string function above support the functionality I am 
looking for? Thanks for the tip on the contains function. 
Already using 
that function to determine if a attribute string value contains 
font-family in the first place.
