測試XML

?

<?xml?version="1.0"?encoding="utf-8"??>
<DongFang>
??<Company>
????<cNname>1</cNname>
????<cIP>1</cIP>
??</Company>
??<Company>
????<cNname>2</cNname>
????<cIP>2</cIP>
??</Company>????
??<Company>
????<cNname>3</cNname>
????<cIP>3</cIP>
??</Company>
??<Company>
????<cNname>4</cNname>
????<cIP>4</cIP>
??</Company>
??<Company>
????<cNname>5</cNname>
????<cIP>5</cIP>
??</Company>
??<Company>
????<cNname>6</cNname>
????<cIP>6</cIP>
??</Company>
</DongFang>

使用方法

?var xmldoc=loadXML(text.xml)

?var elements = xmlDoc.getElementsByTagName("Company");

?for (var i = 0; i < elements.length; i++) {
??????????????? var?name = elements[i].getElementsByTagName("cNname")[0].firstChild.nodeValue;
??????????????? var ip?= elements[i].getElementsByTagName("cIP")[0].firstChild.nodeValue;???????????????

}
