js代码如下:
<html>
<body>
<script type="text/vbscript">
set xmlDoc=CreateObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.load("/example/xpth/books.xml")
set nodes=xmlDoc.selectNodes("/bookstore/book/price/text()")
for each x in nodes
document.write("<xmp>")
document.write(x.xml)
document.write("</xmp>")
next
</script>
</body>
</html>
显示结果如下：
30.00
29.99
我想问的是
for each x in nodes
document.write("<xmp>")
document.write(x.xml)
document.write("</xmp>")
next
这段代码中：for each x in nodes .....next 这个循环是js里面定义的吗？还是xml dom里面定义的？document.write("<xmp>")是xhtml的标签，它表示什么意思？
