Adding separators between vrnlist attributes (CSS based PDF)

I set the version number in the topicmeta of the map:
Code: Select all
<prodinfo>
<prodname>ABC </prodname>
<vrmlist>
<vrm version="6" release="2"/>
</vrmlist>
</prodinfo>
I need to display vrm attributes on the cover page, separated with dots, eg. "6.3.2"
But if only two attributes are set it should be "6.3"
I got this so far but of course it always adds a dot no matter if an attribute is set or not:
Code: Select all
*[class ~= "front-page/front-page-title"]:after {
display:block;
content: "Number: " oxy_xpath('(//*[contains(@class, " map/topicmeta ")]/*[contains(@class, " topic/prodinfo ")]/*[contains(@class, " topic/vrmlist ")]/*[contains(@class, " topic/vrm")]/@version)[1]')"." oxy_xpath('(//*[contains(@class, " map/topicmeta ")]/*[contains(@class, " topic/prodinfo ")]/*[contains(@class, " topic/vrmlist ")]/*[contains(@class, " topic/vrm")]/@release)[1]') "."oxy_xpath('(//*[contains(@class, " map/topicmeta ")]/*[contains(@class, " topic/prodinfo ")]/*[contains(@class, " topic/vrmlist ")]/*[contains(@class, " topic/vrm")]/@modification)[1]');
}
I don't know how to set a conditon at this point, so I could really use a hint here

Finally solved it. Used the merged2merged extension point to create an additional div with the version attributes as value.

Hello,
I'm glad you succeed using XSL and the extension point.
If you still want to do this only using CSS you can use the following selector:
Code: Select all
*[class ~= "front-page/front-page-title"]:after {
display:block;
content: "Number: " oxy_xpath('(//*[contains(@class, " map/topicmeta ")]/*[contains(@class, " topic/prodinfo ")]/*[contains(@class, " topic/vrmlist ")]/*[contains(@class, " topic/vrm")]/@version)[1]')
"." oxy_xpath('(//*[contains(@class, " map/topicmeta ")]/*[contains(@class, " topic/prodinfo ")]/*[contains(@class, " topic/vrmlist ")]/*[contains(@class, " topic/vrm")]/@release)[1]')
oxy_xpath('if ((//*[contains(@class, " map/topicmeta ")]/*[contains(@class, " topic/prodinfo ")]/*[contains(@class, " topic/vrmlist ")]/*[contains(@class, " topic/vrm")]/@modification)[1]) then concat(".", (//*[contains(@class, " map/topicmeta ")]/*[contains(@class, " topic/prodinfo ")]/*[contains(@class, " topic/vrmlist ")]/*[contains(@class, " topic/vrm")]/@modification)[1]) else ""');
}
For simple conditions, XPath support the 'if then else' structure.

Julien

You are right, we will add an example using 'if then else' structure in oxy_xpath() functions inside our documentation.
