[opencms-dev] need help on CmsJspXmlContentBean.contentshow(I_CmsXmlContentContainer container)

[Jonathan Woods]

That sort of String-stashing is what some of the OpenCms code does instead
of returning null, so if you're committed to using that method then you'll
have to check for the "???..." String.
 
Alternatively, you could use some of the other XML-related API, and process
XML element content more directly.

CmsJspXmlContentBean.contentshow(I_CmsXmlContentContainer container) 


I am using CmsJspXmlContentBean.contentloop and
CmsJspXmlContentBean.contentshow to read data from structured content.
I wonder how to check existance of a field before I do contentshow.
I expect contentshow(I_CmsXmlContentContainer container) return null on a
non-exist field (for that field I didnt click the Add button which showing
"(Click on the New button on right side...)"). 
but it returns "??? fieldname ???"

any help?


Joe
