Rust-Etree

XML DOM library with XPath support.

Usage

Put this in your Cargo.toml:

toml [dependencies] etree = "0.1"

```rust use etree::*; use std::path::Path;

fn createxml>(path:P) { let mut tree:ETree = ETree::from(ETreeNode::new("ROOT")); tree.setencoding("UTF-8"); tree.setstandalone("no"); let rootpos = tree.root();

// append first child
let mut child1:ETreeNode = ETreeNode::new("CHILD-A");
child1.set_attr("DEST", "CHN");
let child1_pos = tree.append_child_node(root_pos, child1).unwrap();
// append another child after first child
let mut child2:ETreeNode = ETreeNode::new("CHILD-B");
child2.set_text("Shanghail");
tree.append_next_node(child1_pos, child2);
// append another child before first child
let mut child3:ETreeNode = ETreeNode::new("CHILD-C");
child3.set_attr("DEST", "CHN");
child3.set_text("Shanghail");
tree.append_previous_node(child1_pos, child3);
// append a child in the first child
let mut child4:ETreeNode = ETreeNode::new("SUBCHILD-A");
child4.set_text("EAST");
let pos = tree.find("//CHILD-A"); // after inserting child3, child1_pos becomes invaild
tree.append_child_node(pos[0], child4);
tree.pretty("\n  ");
tree.write_file(path).ok();

}

fn modifyxml>(pathin:P, pathout:P) { let mut tree = ETree::parsefile(pathin); let subtreepos = tree.find("//CHILD-A"); assert!(subtreepos.len() == 1); let mut subtree = tree.subtree(subtreepos[0]); let subtreechildpos = subtree.find("/SUBCHILD-A"); assert!(subtreechildpos.len() == 1); if let Some(node) = subtree.nodemut(subtreechildpos[0]) { node.settext("WEST"); } // tree.appendnexttree(subtreepos[0], subtree.clone()); let parentpos = tree.parent(subtreepos[0]).unwrap(); tree.appendchildtree(parentpos, subtree); tree.writefile(pathout).ok(); } ```
