Subject: Re: [xsl] Count a substring of an attribute in childnodes From: David Carlisle <davidc@xxxxxxxxx> Date: Wed, 9 Mar 2005 10:58:47 GMT |
> But this one gives me <Output>NaN</Output> does it? what system? <xsl:variable name="total-colwidth" select="'count(number(colspec[contains(@colwidth,'*')]/substring-before(@colwidth,'*')))'"/> That selects the string 'count(number(colspec[contains(@colwidth,'*')]/substring-before(@colwidth,'*')))' which you output using <xsl:value-of select="$total-colwidth"/> so you should get <Output>count(number(colspec[contains(@colwidth,'*')]/substring-before(@colwidth,'*')))</Output> Unless something is seriously wrong with your system. If you took away the string quotes so it was an XPath expression you woul dget an error as count() counts items in a node set (it doesn't calculate totals which is what you indicated you wanted to do) but number() returns a number not a node set. In Xpath2 draft you could do <xsl:value-of select="sum(colspec/@colwidth/number(translate(.,'*','')))" In XSLT11 you have to use a recursive template to accumulate the sum by hand adding a new value on each iteration, you could use one of Dimitre's FXSL procedures for example, or just code it directly.
