Enhance Blog Design Expansions to The Blogger Template

Earlier Blogger introduced a new set of XML expansions to the Blogger template engine, designed to let you flexible editing and customization of blogger’s each blog post and page HTML codes. These expressions containing a set of widget tags which are used to comparison, conditional  and loops to change the design and outputs of each blog post and pages.

Blogger now, supports many more expression operators, including:

    Inversion of Boolean data true/false values with !/not

    Like <b:if cond='!data:post.allowComments'>...

    Preference conditional values with ?:

    e.g. <a expr:class='data:post.allowComments ? "comments" : "no-comments"' ...

    Checking if a value is a member of a set or array, with in/contains

    e.g. <b:if cond='data:blog.pageType in {"index", "archive"}'>...

    Relating multiple conditions with Logical Operators and/or

    e.g. <b:if cond='data:blog.pageType == "index" and data:post.allowComments'>...

    Changing the order of operations with Postfix operator ()

    e.g. <div expr:style='"max-width: " + (data:width + 10) + "px;"'>...

Now you can try out new design tags, like:

    <b:elseif for a simpler multiple-case b:if branch.

   <b:switch and b:case for succinctly handling several possible cases of a variable.

    <b:eval for evaluation of more complex expressions involving data variables.

    <b:with for creating a nicer variable alias for a calculated value.
