HTML Encoding the string will likely alter its length. If you were expecting the content to be 100 characters that change will probably not be significant, but when you’re looking for 10 characters encoding an “&” to “&” arbitrarily removes 40% of your capacity.
It should be obvious by now that using a render tag is not the way to solve this problem. Are you publishing to PHP or ASPX? Use the runtime language support to alter the display on the fly. Are you publishing to HTML? Use JavaScript. You’re breaking a walnut with explosives.

However, I'm not sure why you get "Less then 10" (which is in fact "Less than or equal 10"). A slightly better solution for this problem could be to not insert the text placeholder into the page but to grab it from the RenderTag directly. This way you do not need any Escaping and do not run into problems with characters in the element that break the RenderTag. You can get an element of the current page this way (this should print out the length of the element txt_teaser): <%!! Context:CurrentPage.GetElementByName(txt_teaser).Value.Length !!%> If you are using an element transfered via list/dyn anchor you need to get the page first and then the element (the inf_... is an info element to get the guid of the page which is iterated in the list): <%!!

I got an off-list suggestion to change '...(<%txt_content%>)...' to just '...(txt_content)...', which got the comparison to at least render the output message. It returned 'Less than 10' as the message, despite being over 2,000 chars, so something still not right: <if> <query valuea="Escape:Text(txt_content).Length" operator=">" valueb="Int:10"> <htmltext>------ Over 10 ------</htmltext> </query> <query type="else"> <htmltext>------ Less than 10 ------</htmltext> </query> </if> -- You received this message because you are subscribed to the Google Groups "RedDot CMS Users" group.
