Javascript 删除xml中属性等于某物的行

我有以下xml，XMLApplicationActivityType：

<ApplicantActivityType>
  <Row codeName="ALL" codeDisplayName="- All activity type(s) - " selected="1"/>
  <Row codeName="REVGNMO" codeDisplayName="Reverse Give Notice" selected="0"/>
  <Row codeName="COLLECT" codeDisplayName="Collections" selected="0"/>
  <Row codeName="COMPLT" codeDisplayName="Complaint" selected="0"/>
  <Row codeName="DCOMT" codeDisplayName="Delinquency comments" selected="0"/>
  <Row codeName="GENNOTE" codeDisplayName="General note" selected="0"/>
  <Row codeName="PCOMT" codeDisplayName="Prepaid comments" selected="0"/>
  <Row codeName="SCRNOTE" codeDisplayName="Screening note" selected="0"/>
  <Row codeName="TFRSITE" codeDisplayName="Transferred to sister site" selected="0"/>
  <Row codeName="TFRUNIT" codeDisplayName="Transferred to new unit" selected="0"/>
</ApplicantActivityType>

如何使用javascript实现这一点

我所做的如下，但我得到了错误：

var a = xmlApplicantActivityType.getElementsByTagName("ApplicantActivityType")[0];
var rows = a.childNodes;
    if(rows)
    {
        for(var i = 0; i < rows.length; i++)
        {
          var codeName = rows[i].getAttribute("codeName");


          if(codeName == "REVGNMO")
          {
          refnode = xmlApplicantActivityType.selectSingleNode("//ApplicantActivityType/Row[@codeName='REVGNMO']");

          xmlApplicantActivityType.selectSingleNode("//Row").removeChild(refnode);           
          }

         }
    }

var a=XMLApplicationActivityType.getElementsByTagName（“ApplicationActivityType”）[0]；
var rows=a.childNodes；
如果（行）
{
对于（变量i=0；i

Nevermind，在这里找到答案：

var a = xmlApplicantActivityType.getElementsByTagName("ApplicantActivityType")[0];
var rows = a.childNodes;
    if(rows)
    {
        for(var i = 0; i < rows.length; i++)
        {
          var codeName = rows[i].getAttribute("codeName");


          if(codeName == "REVGNMO")
          {
          refnode = xmlApplicantActivityType.selectSingleNode("//ApplicantActivityType/Row[@codeName='REVGNMO']");

          xmlApplicantActivityType.selectSingleNode("//Row").removeChild(refnode);           
          }

         }
    }

var a = xmlApplicantActivityTypeOnly.getElementsByTagName("ApplicantActivityType")[0];
        refnode = xmlApplicantActivityTypeOnly.selectSingleNode("//ApplicantActivityType/Row[@codeName='REVGNMO']");
        a.removeChild(refnode);
