使用xpath.js NPM模块解析XML

Question

My XML looks like this:

<jobs>
  <job>
    <title>Engineer - System Planning</title>
    <url>http://my.jobs/0629cdc680d04cf3bcd711a1c0b69836321</url>
    <company>Iberdrola USA</company>
    <location>Augusta, ME</location>
    <dateacquired>2013-3-22 6:24 PM</dateacquired>
    <jvid>0629cdc680d04cf3bcd711a1c0b69836321</jvid>
  </job>
  <job>
    <title>Engineer - Hydro</title>
    <url>http://my.jobs/61cccbfba50c4f93a5169aafc13c82b2321</url>
    <company>Iberdrola USA</company>
    <location>Rochester, NY</location>
    <dateacquired>2013-7-5 8:33 PM</dateacquired>
    <jvid>61cccbfba50c4f93a5169aafc13c82b2321</jvid>
  </job>
</jobs>

And I am wanting to use the XPath.js NPM Module ( https://www.npmjs.org/package/xpath.js ). but I am just not sure how to loop through each job in the XML document using that module

Answer 1

From the first example in the xpath.js documentation , with an XPath expression like //job you'll get a node-set:

var nodes = select(doc, "//job");

which you can loop using regular JavaScript, since it's an array. You can then pass each node as a parameter in another XPath expression and obtain the data inside the other nodes:

for (i = 0; i < nodes.length; i++) {
    var title   = select(nodes[i], "title/text()")[0].data;
    var url     = select(nodes[i], "url/text()")[0].data;
    var company = select(nodes[i], "company/text()")[0].data;
    ...
}
