Re: [exslt] Need help on using Math Functions
& XSLT Hi there,
I want to call math:sqrt(input_argument) function. If I assign value of
price is a hard code, <xsl:variable name="price" select="25" /> , and
<xsl:variable name="sqrtOfPrice" select="math:sqrt($price)" /> , I don't
have any problem; However, if I define the price represents a value of a
node set, like <xsl:variable name="price"
select="catalog/cd/price[position()=1]" /> , then the
math:sqrt(input_argument) function can not recognize the value of price.
The error that I got as "Microsoft JScript runtime error Wrong number of
arguments or invalid property assignment line = 2, col = 20 (line is
offset ...". I tried to call math function at xsl:stylesheet section and
at xsl:template section. I still don't have any luck Please, some body
help me.
Below are my sample codes to call math:sqrt() function.
