Tree::...ariable(3pm)

🌸 NAME 🌸

Tree::XPathEngine::Variable — bestie, it's literally a variable in a Tree::XPathEngine object 💖

So this lil page is part of the User Contributed Perl Documentation situation, and the module it's hyping up is Tree::...ariable (yes that's how the title bar shows it, she's shy, she truncates). Anyway. Sit down, grab a strawberry 🍓, let's talk variables.

✨ METHODS ✨

okay so REAL TALK first, because this trips everyone up: this class does NOT contain 1 instance of a variable. Not even one. The actual variable instance lives in the Tree::XPathEngine class, periodt. What this class does is hold the name of the var — that's it, that's the whole job — so the engine can go find it when it's evaluating the query. She's the name tag, not the person 💅

🎀 new

makes a new one. iconic behaviour.

🦋 xpath_set_value

sets the value. (iykyk)

💜 xpath_get_value

this one is a synonym of get_value — same energy, different spelling, she contains multitudes ✨

🌈 evaluate

evaluates. go off queen 👑

👑 as_string

dump the variable call in the XPath expression as a string. fr fr, that's the whole thing — she turns the variable call into string form.

🌸 as_xml

dump the variable call in the XPath expression as xml. same vibe as as_string but make it XML 🎀

lowkey a tiny class but highkey essential — without the name-holder, the engine wouldn't know which variable to grab when it's out here evaluating queries. not me being emotionally attached to a Perl class 😭

Tree::...ariable(3pm) — that's a wrap, bestie 🌈💅
