Tree::...unction(3pm)

💖 Tree::XPathEngine::Function 💖

okay bestie, so this little icon is a Perl module — part of the User Contributed Perl Documentation — and its whole gig is evaluating XPath functions. that's it, that's the vibe. she takes XPath functions and she evaluates them. periodt. ✨

---

🌸 METHODS 🌸

new 🌱

it makes a new one. constructor behaviour, standard issue, no notes. 💅

evaluate 🧠

evaluate the function on a nodeset. yes queen, that's the entire job description. 🫶

_execute ⚙️

evaluate the function on a nodeset. (yes, same energy as evaluate — the underscore is lowkey giving "internal, don't touch" but that's just how it's listed, iykyk.) 🔥

as_string 🎀

dump the function call as a string. textual glow-up, slay. ✨

as_xml 🦋

dump the function call as xml. same but make it markup, iconic. 🌈

reminder bestie: this page doesn't spell out what each function does — it literally says See the specs for details — so don't come for me, go read the specs. 💖

and that's a wrap on the Tree::XPathEngine::Function page, brought to you by perl v5.36.0, dated 2022-11-20, and lovingly shipped as part of the User Contributed Perl Documentation. go forth and evaluate, mwah 🫶💅🌸
