Assembly for XML

Xembly is an Assembly-like imperative programming language for data manipulation in XML documents. Read this blog post for a more detailed explanation: Xembly, an Assembly for XML.

For example, you have an XML document:

<orders>
  <order id="553">
    <amount>$45.00</amount>
  </order>
</orders>

And you want to change the amount of the order #553 from $45.00 to $140.00. Xembly script would look like:

XPATH "orders/order[@id=553]";
SET "$140.00";

It is much simpler and compact than XSLT or XQuery.

This Java package implements Xembly:

Document document = DocumentBuilderFactory.newInstance()
  .newDocumentBuilder().newDocument();
Iterable<Directive> dirs = new Directives(
  "ADD 'orders'; ADD 'order'; ATTR 'id', '553'; SET '$140.00';"
);
new Xembler(dirs).apply(document);

Since version 0.9 you can directly transform directives to XML:

String xml = new Xembler(
  new Directives()
    .add("root")
    .add("order")
    .attr("id", "553")
    .set("$140.00")
).xml();
