variables in xslt

Question

I am getting a particular value by using

<xsl:value-of select="@date" />

and i want to store this value as a variable say 'd' How can i do this and also tell me how can i use that caribale back in my template. Thanks in advance

Here's one I've been bitten by often: storing the results of boolean expressions in variables won't work the way you might expect. <variable name="x" select="1=2"/> will store the string "false" in x, and "false" is, of course, TRUE because it's a non-empty string. — bendin

<xsl:variable name="d" select="@date" />
<xsl:value-of select="$d" />

Looking through the basics might be worthwhile. ;-)

That would be

<xsl:variable name="date" select="@date" />

to declare a symbol referencing the node @date.

To use it later on you can reference that symbol by prefixing the name with $:

<xsl:value-of select="$date" />

Note that once the symbol is declared you cannot change its value in XSLT.

@divo: Casual nitpicking: You're not declaring a symbol with the value of @date, but rather one with a reference to the node.

Thanks Tomalak, my mistake. That's actually quite a difference.
