[src]
macro_rules! vtd_for_children { ($vn: ident, $tag: expr, $default: expr, $code: block) => { ... }; ($vn: ident, $tag: expr, $code: block) => { ... }; }
Loop over the immediate children with the given tag name.
The loop might return a value using the break value
mechanics.
For example:
let xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><foo>bar</foo>"; let mut vg = VtdGen::new(); vg.parse_vec (false, Rc::new (xml.into()), 0, xml.len()); let mut vn = VtdNav::new (&mut vg); let first_bar = vtd_for_children! (vn, "foo", String::new(), {break vn.text().clone()});
vn
-VtdNav
instance. Children are searched for immediately under the current position.tag
- The name of the child XML tag. We skip any children not matching the tag name.default
- Default return value of the loop. Set it to()
if you're not returning a value.code
- A block of code that is run for every child matching thetag
