やら〜やらWhether or, Things like, And … so on

やら is an adverbial particle in Japanese which expresses lack of determination or limitation in regard to (A). Due to this, it is very similar to other structures like など, and will often translate as '(A) and so on', or '(A) and the like'.

やら may appear following verbs in their dictionary form, nouns, い-Adjectives, or な-Adjectives. When repeated as (A) やら (B) やら, both (A) and (B) will often be the same type of word, although this is not a limitation when the speaker is expressing various feelings in relation to something.

Compared to とか, やら puts more emphasis on the scope of things within the category of (A) and (B), thus making it sound like (A) and (B) are only a small fraction of many different things within a complex pool of various emotions, actions, etc.

Caution

When appearing as のやら～のやら, this emphasizes that the speaker does not actually know which one out of (A) and (B) is the correct option, and is just presenting both as potential possibilities. Due to this, (A) and (B) will often be antonyms or opposites of some sort in these types of sentences, but not always.
