The below code loads the data from the XML to asp.net listbox and assign default selected value to first item.  How could i code so that it will selecte all items  by default?  and also show me how to select the items dynamically based on value from XML (refer below the XML structure)

dsIndexes.ReadXml(filepath);
lstIndexList.DataSource = dsIndexes.Tables[0];
//LBIndexList.DataMember = Indexes;
lstIndexList.DataTextField = dsIndexes.Tables[0].Columns[1].ToString();
lstIndexList.DataValueField = dsIndexes.Tables[0].Columns[2].ToString();
lstIndexList.DataBind();
 lstIndexList.SelectedIndex = 0;

XML structure is as below

<?xml version="1.0" encoding="utf-8" ?>
<Indexes>
  <Index>
    <Index_ID Selected=true>01</Index_ID>
    <Index_Name>dfdfdfdsf</Index_Name>
    <Index_URL>dsdsfdfdf</Index_URL>
  </Index>
 <Index>
    <Index_ID Selected=false>02</Index_ID>
    <Index_Name>dfdfdfddererer</Index_Name>
    <Index_URL>dfsdfdfdfd</Index_URL>
  </Index>
</Indexes>
