XML : getting values from xml with conditions given using c#

hi guys im kinda new with using xml with c#.

XML CODE:

  <LVL2>    <Tables>      <TBL_ID>1</TBL_ID>      <TBL_Name>test1</TBL_Name>      <MD_ID>1</MD_ID>    <Tables>    <Tables>      <TBL_ID>2</TBL_ID>      <TBL_Name>test2</TBL_Name>      <MD_ID>1</MD_ID>    </Tables>    <Tables>      <TBL_ID>3</TBL_ID>      <TBL_Name>test3</TBL_Name>      <MD_ID>1</MD_ID>    </Tables>  </LVL2>    <LVL2>    <Tables>      <TBL_ID>1</TBL_ID>      <TBL_Name>test4</TBL_Name>      <MD_ID>2</MD_ID>    </Tables>    <Tables>      <TBL_ID>2</TBL_ID>      <TBL_Name>test5</TBL_Name>      <MD_ID>2</MD_ID>    </Tables>    <Tables>      <TBL_ID>3</TBL_ID>      <TBL_Name>test6</TBL_Name>      <MD_ID>2</MD_ID>    </Tables>  </LVL2>    

how do I insert to a checklistbox the text values from tbl_name that has an md_id = 1 only. here is my current code.

  while (xmlReader.Read())                  {                      switch (xmlReader.NodeType)                      {                            case XmlNodeType.Element:                              elName = xmlReader.Name;                              break;                          case XmlNodeType.Text:                                if (elName == "TBL_Name" && MD_ID == "1")                              {                                  checkedListBox2.Items.Add(xmlReader.Value);                              }                                break;                          }                  }    

i cant seem to figure out on how to get the text that has MD_ID = "1" and output

  test4  test5  test6
