JS获取XML内容!-优快云博客

XML

<?xml version="1.0" encoding="GB2312"?>

<email>ajie@aolhoo.com</email>

</myfile>

JS:

<html>

<head>

var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");

xmlDoc.async="false";

xmlDoc.load("myfile.xml");

root = xmlDoc.documentElement;

//nodes = xmlDoc.documentElement.childNodes;

document.all("title").innerText = root.childNodes.item(0).text;

document.all("author").innerText = root.childNodes.item(1).text;

document.all("email").innerText = root.childNodes.item(2).text;

document.all("date").innerText = root.childNodes.item(3).text;

</script>

<title>在HTML中调用XML数据</title>

</head>

这里XMLDoc相当于.NET里的,
XmlDocument这样就可以通过XPATH来选择XML里的内容了:

items = xmldoc.selectNodes("invoices/invoice");
items = xmldoc.selectNodes("*/invoice");
items = xmldoc.documentElement.selectNodes("invoice");

function invoiceTotal(invoice)
{
  invoice = invoice.nextNode()
  items = invoice.selectNodes("items/item");
  var sum = 0;
  for (var item = items.nextNode(); item; item = items.nextNode())
  {
    var price = item.selectSingleNode("price").nodeTypedValue;
    var qty = item.selectSingleNode("qty").nodeTypedValue;
    sum += price * qty;
  }
  return sum;
}
