Firstly, don't use this construction:
<xsl:variable name="image_src">
<xsl:value-of select="./@url"/>
</xsl:variable>
Instead, write:
<xsl:variable name="image_src" select="./@url"/>
That's nothing to do with this problem but it's a bad and very common coding
habit that you should try to break.
If the variable is a global variable, as you seem to be suggesting, then "."
is the root (document) node, and document nodes don't have any attributes.
If your XML only contains the one element you showed, then you should do
select="/graphic/@url".

Subject: [xsl] [XSL] Calculating Length of String Variables
Hi,
I am trying to create different sets of output based on the
length of the "string" of my variable. Below are the lines I
used for calculation:
<xsl:variable name="image_src">
<xsl:value-of select="./@url"/>
</xsl:variable>
<xsl:template match="graphic">
<xsl:value-of select="string-length($image_src)"/>
</xsl:template>
If I have XML like: <graphic url="0125"/>. the result is
supposed to come out with 4. And, likewise, <graphic
url="123456"/> should come out with 6. However, when I run
the XSLT, it only gives me "0". Is there something I have done wrong?
Thanks to those who may help.
Alice
