Question

我在下面有XML参数;如您所见，这是两个“网关”节点。第一个有接口内部，第二个有接口Uplink。

我想添加新的 IpRange ， StartAddress 和 EndAddress 子节点。但首先，我需要找到具有上行链路接口的Gateway节点，并在此处附加IpRange参数。像x.x.x.x。

我是XML新手，我使用的是javascript和HTML DOM。

<Gateways>
            <Gateway>

                <Subnet>
                    <Gateway>1.1.1.2</Gateway>
                    <Netmask>255.255.255.0</Netmask>
                    <IpAddress>1.1.1.1</IpAddress>
                </Subnet>             
            </Gateway>          
            <Gateway>
                <Interface>uplink</Interface>
                <Subnet>
                    <Gateway>2.2.2.2</Gateway>
                    <Netmask>255.255.255.0</Netmask>
                    <IpAddress>2.2.2.1</IpAddress>
                    <IpRanges>
                        <IpRange>
                            <StartAddress>x.x.x.x</StartAddress>
                            <EndAddress>x.x.x.x</EndAddress>
                        </IpRange>
                           <IpRange>
                            <StartAddress>x.x.x.x</StartAddress>
                            <EndAddress>x.x.x.x</EndAddress>
                        </IpRange>
                    </IpRanges>
                </Subnet>
            </Gateway>
</Gateways>

try with this JS code mad by XML DOM function:

  var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function () {
    if (this.readyState == 4 && this.status == 200) {
      readXML(this);
    }
  };
  xhttp.open("GET", "yourFile.xml", true);
  xhttp.send();

  function readXML(xml) {
    var newElement, xmlDoc;
    //New xmlDoc
    xmlDoc = xml.responseXML;
    //Looking for the right interface node
    var InterfaceNode = xmlDoc.getElementsByTagName("Interface").nodeValue;
    for (let i = 0; i < xmlDoc.getElementsByTagName("Interface").length; i++) {
      //The one with value = 'uplink'
      if (xmlDoc.getElementsByTagName("Interface")[i].nodeValue == 'uplink') {
        var IpRangesNode = xmlDoc.getElementsByTagName("IpRanges")[i];
        //Creating the new node IpRange
        newElement = xmlDoc.createElement("IpRange");
        //Adding 2 new nodes StartAddress and EndAddress both with  x.x.x.x as value
        var newStartAddress = newElement.createElement("StartAddress");
        newStartAddress.nodeValue = "x.x.x.x";
        var newEndAddress = newElement.createElement("EndAddress");
        newEndAddress.nodeValue = "x.x.x.x";
        //Appending to the initial Node
        IpRangesNode.appendChild(newElement);
      }
    }
  }

Hope this could help, Laura.
