+Use `compile` from `xjslt/compile` to build a transform function directly in
+Node.js without writing any files to disk. The stylesheet is passed as a parsed
+document, and the returned function can be called immediately.
+
+```ts
+import * as slimdom from "slimdom";
+import { readFileSync } from "fs";
+import { compile } from "xjslt/compile";
+
+const stylesheetPath = "jats-html.xsl";
+const xslt = slimdom.parseXmlDocument(readFileSync(stylesheetPath, "utf-8"));
+const transform = await compile(xslt);
+
+// Transform an XML document
+const input = slimdom.parseXmlDocument(readFileSync("article.xml", "utf-8"));
+const results = transform(input);
+const resultDocument = results.get("#default");
+
+const xml = slimdom.serializeToWellFormedString(resultDocument);
