Hi,
I'm using Saxon-B 9.0.0.6 that comes with Oxygen 9 for profiling. My Stylesheet is quite long so i don't wan't to post the whole thing but my problems seems to reside within one template anyway.
I have the following template:
<xsl:template match="*[self::p or self::ul][following::text()[starts-with(.,'Zum aktuellen Rechtsstand')] and ancestor::div[@class='comm.body'] and text()][1]" priority="20"> ***something happens*** </xsl:template>
When i change the xpath to
<xsl:template match="*[not(ancestor-or-self::span[@class='heading' and count(preceding::span[@class='heading']) = 0])][self::p or self::ul or self::span[not(@class='heading' and count(preceding::span[@class='heading']) = 0)]][following::text()[starts-with(.,'Zum aktuellen Rechtsstand')] and ancestor::div[@class='comm.body'] and .//text()][1]" priority="20"> **still same things happens** </xsl:template>
it adds 104 seconds to the execution time. Problem is i need to change it because otherwise it matches thing it's not supposed to.
Can anyone tell me what exactly I'm doing that is causing this performance break ? As soo as i revert that one change execution time goes down again.
cheers
