Re: [xsl] [XSL] Calculating Length of String Variables

[jingjun long <longjingjun@xxxxxxxxx>]

Alice,

When you define image_src variable, there is a context there (The 
context is not in graphic element aparently). If there is not an url 
attribute for current element, you will get empty when you say 
<xsl:value-of select="./@url"/>. So the result is 0.

If you change your program to:

<xsl:template match="graphic">
	<xsl:value-of select="string-length(@url)"/>
</xsl:template>

OR:

<xsl:template match="graphic">
	<xsl:variable name="image_src">
       	<xsl:value-of select="./@url"/>
	</xsl:variable>
	<xsl:value-of select="string-length($image_src)"/>
</xsl:template>

It should work.

Hope this helps.
