I need to select MarkNameNodes (with MarkObjectType='TEXT') and its LaserFontNodes, InkFontNodes from a xml document. If a LaserFont or InkFont nodes are not found, display '-".

I have this code :

var MarkNameNodes=theRoot.selectNodes("//MarkTemplate["0"]/MarkingObjects/MarkObject[MarkObjectType='TEXT']/MarkName");
var LaserFontNodes=theRoot.selectNodes("//MarkTemplate["0"]/MarkingObjects/MarkObject[MarkObjectType='TEXT']/LaserFont");
var InkFontNodes=theRoot.selectNodes("//MarkTemplate["0"]/MarkingObjects/MarkObject[MarkObjectType='TEXT']/InkFont");

var strMarkObjectTable="<table border='1' id='MarkObjectGroup'>";
strMarkObjectTable += "<tr><td>MarkName</td><td>Laser</td><td>Ink</td></tr>";

for (i=0;i<MarkNameNodes.length;i++){
      if ( MarkNameNodes.item(i) != null ) {
              strMarkObjectTable += "<tr><td>"+ MarkNameNodes.item(i).text +"</td>";
      } else {
                strMarkObjectTable += "<td>-</td>";
      }

       if (LaserFontNodes.item(i) != null ) {
              strMarkObjectTable += "<tr><td>"+ LaserFontNodes.item(i).text +"</td>";
      } else {
                strMarkObjectTable += "<td>-</td>";
      }

       if ( InkFontNodes.item(i) != null ) {
              strMarkObjectTable += "<tr><td>"+ InkFontNodes.item(i).text +"</td>";
      } else {
                strMarkObjectTable += "<td>-</td>";
      }

       strMarkObjectTable += "</tr>";
}
strMarkObjectTable += "</table><br>";
divMarkObject.innerHTML=strMarkObjectTable;          


it returns me the result of :

MarkName     Laser      Ink
----------------------------------
001               12           12
002               12            9
003               -            -

the correct result should be :  
MarkName     Laser      Ink
----------------------------------
001                -            12
002               12            9
003               12            -

this is the xml :

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfMarkTemplate>
  <MarkTemplate>
    <MarkType>MARKTYPE001</MarkType>
    <ImageId>854</ImageId>
    <MarkingObjects>
      <MarkObject>
        <MarkName>001</MarkName>
        <MarkObjectType>TEXT</MarkObjectType>
        <InkFont>12</InkFont>
      </MarkObject>
      <MarkObject>
        <MarkName>002</MarkName>
        <MarkObjectType>TEXT</MarkObjectType>
        <LaserFont>12</LaserFont>
        <InkFont>9</LaserFont>
       </MarkObject>
      <MarkObject>
        <MarkName>003</MarkName>
        <MarkObjectType>TEXT</MarkObjectType>
        <LaserFont>12</LaserFont>      
      </MarkObject>
      <MarkObject>
        <MarkName>004</MarkName>
        <MarkObjectType>GRAPHIC</MarkObjectType>
        <ObjectText>GRAPHIC001</ObjectText>
         <InkFont>10</InkFont>
      </MarkObject>
    </MarkingObjects>
  </MarkTemplate>
  <MarkTemplate>
   ......
  </MarkTemplate>

</ArrayOfMarkTemplate>

Please advise in what is the right way to code to get the correct result.

Hi sherly,

selectNodes gives you the set of nodes that do exist
so your result is a pretty logical one

why don't you select the MarkObject
and access the childNodes, if existent as childnodes of this MarkObject node
Then you are sure that the allignment is correct

Cheers!

sherly,

here is an example (I simply add nodenames and content to a string "test")

         var MarkObjectNodes=oXML.selectNodes("//MarkTemplate[1]/MarkingObjects/MarkObject[MarkObjectType='TEXT']");
                    for (i=0; i<MarkObjectNodes.length; i++)
                    {
                        for (j=0; j<MarkObjectNodes[i].childNodes.length; j++)
                              {
                                  test = test + (MarkObjectNodes[i].childNodes[j].nodeName);
                                  test = test + ("=");
                                  test = test + (MarkObjectNodes[i].childNodes[j].childNodes[0].nodeValue);
                                  test = test + ("<br />");
                              }                        
                    }        

you can fill in your logic yourself, by testing for the nodeName and adding the value or a "-"

cheers

I believe you'd want something like this, with <tr> tags, and <td> tags
Each of the 3 nodes are tied to the particular object node.
Also, the data is replaced with '-' if the node is empty.

var MarkObjectNodes=oXML.selectNodes("//MarkTemplate[1]/MarkingObjects/MarkObject[MarkObjectType='TEXT']");
for (i=0; i<MarkObjectNodes.length; i++)
{
        strMarkObjectTable += "<tr>";            
      var MarkObjectNode = MarkObjectNodes.Item(i);
      var MarkNameNode   = MarkObject.SelectSingleNode("MarkName");
      var LaserFontNode  = MarkObject.SelectSingleNode("LaserFontNode");
      var InkFontNode    = MarkObject.SelectSingleNode("InkFontNode");


        strMarkObjectTable += "<td>";                  
        if (MarkNameNode != null) {
            strMarkObjectTable += MarkNameNode.text;
        } else {
                strMarkObjectTable += "-";
        }
        strMarkObjectTable += "</td>";                  

        strMarkObjectTable += "<td>";                  
        if (LaserFontNode != null) {
            strMarkObjectTable += LaserFontNode.text;
        } else {
                strMarkObjectTable += "-";
        }
        strMarkObjectTable += "</td>";            

        strMarkObjectTable += "<td>";                        
        if (InkFontNode != null) {
            strMarkObjectTable += InkFontNode.text;
        } else {
                strMarkObjectTable += "-";
        }
        strMarkObjectTable += "</td></tr>";            
}
