pub fn attr(

tree: element.ElementTree,
) -> List(#(String, String))Gets attributes of the given element. TextNodes will return []
pub fn children(
tree: element.ElementTree,

pub fn find_all(
from in: a,
with fun: fn(a) -> List(a),
) -> List(a)Runs the given function recursively over the result until it no longer results in items. Returns the found nodes from every level
pub fn find_leaf(
from in: a,
with fun: fn(a) -> List(a),
) -> List(a)Runs the given function recursively over the result until it no longer returns items. Returns only the deepest matching nodes

) -> Result(element.ElementTree, Nil)pub fn get_children_by_tag(
