Blogger AND Operator

I was skimming through this theme template XML, and I noticed there was the and being used inside the condition of b tag.

The last image above, you can see even OR operator is written conveniently as or!

Perhaps that is not new to some of you, but to me, that is NEW! 😄 I do actually implement that to my own logic in the Blogger XML template.

But of course, it again depends on the logic.

We can do this:

if (condition_1) { if (condition_2) { // condition_1 AND condition_2 are satisfied } else { // Only condition_1 (outer) is satisfied } } else { // None of the condition }

Or this:

if (condition_1 && condition_2) { // condition_1 AND condition_2 are satisfied } else { // None of the condition }

Example

I mostly implement the second one. So, it's quite convenient to write it like regular coding syntax.

For instance, this nesting:

<b:if cond='data:blog.pageType == "item"'> <b:if cond='data:blog.url != "specific-URL-on-the-blog"'> [...content1...] </b:if> <b:else /> [...content2...] </b:if>

Can be written as such:

<b:if cond='data:blog.pageType == "item" and data:blog.url != "specific-URL-on-the-blog"'> [...content1...] <b:else /> [...content2...] </b:if>

Quite nifty indeed! All hail Blogger! 🫡

Let’s Apply That to Hair Conditioner XML Tag

<b:if cond='data:hair.dryness == "extreme" and data:hair.type == "curly"'> <apply:conditioner type="deep-moisture" /> <b:else /> <apply:conditioner type="light-weight" /> </b:if>

XML in hair conditioner Blogger tag stands for eXtremely Marvelous Lice-repellent. This is an amusement

<b:if cond='data:hair.status == "infested"'> <apply:shampoo type="anti-lice" /> <b:else /> <apply:shampoo type="volumizing" /> </b:if>

For our information, Blogger implements XHTML 1.0 instead of pure XML. That is the "offspring" of XML and HTML ➡️ it has the regular HTML tags nesting syntax but with XML strictness for tag enclosing and tag attribute value. Plus, it accommodates Blogger's custom server-side data tags.

Your visit is much appreciated. Cheers 🙂
