it should still fix some issue You get one node for the circle and one node for the filling of the circle. Try removing circle.fillColor = UIColor.blackColor(). Now the number of nodes only increases by 1.

Exclude last occurance of duplicate nodes. Duplicates nodes are nodes with multiple attributes with same values

Exclude last occurance of duplicate nodes. Duplicates nodes are nodes with multiple attributes with same values

I think the issue was by ths following ,
I have been trying to write an XPath/XSLT for my problem of detecting and eliminating duplicate nodes. In my case, duplicate nodes are nodes with multiple attributes with same values. The way I want to eliminate duplicate is by excluding the last occurrence of the duplicate node. Please advice if there is any other method.

    <record id="4" operator1='xxx' operator2='yyy' operator3='zzz'/>

Hope this helps I had a tough time formulating the question title. Maybe the example will make more sense. , This transformation is quite simpler (only 3 templates and no modes):
code :
<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:key name="kPhNumByType" match="phone_number"
  use="@type"/>

 <xsl:key name="kAddrByType" match="email_address"
  use="@type"/>

 <xsl:variable name="vallTypes" select=
 "/*/*/*/@type
          [generate-id()
          =
           generate-id(key('kTypeByVal',.)[1])
          ]"/>

 <xsl:template match="/">
  <root>
   <addresses>
    <xsl:apply-templates select="$vallTypes"/>
   </addresses>
  </root>
 </xsl:template>

 <xsl:template match="@type">
  <xsl:variable name="vcurType" select="."/>
  <xsl:variable name="vPhoneNums" select="key('kPhNumByType',.)"/>
  <xsl:variable name="vAddresses" select="key('kAddrByType',.)"/>

  <xsl:variable name="vLonger" select=
  "$vPhoneNums[count($vPhoneNums) > count($vAddresses)]
  |
   $vAddresses[not(count($vPhoneNums) > count($vAddresses))]
  "/>

  <xsl:for-each select="$vLonger">
   <xsl:variable name="vPos" select="position()"/>
   <address name="{$vcurType}{$vPos}">
    <xsl:apply-templates select="$vPhoneNums[position()=$vPos]"/>

   </address>
  </xsl:for-each>
 </xsl:template>

Hope this helps I resolved this issue by downloading the latest version of FancyTree which is 2.3.0. The issue was when click on a node and used check it, it used to become the active row. So if were expanding another root node, it used to automatically expand the node where the active row was.

this will help You could store the path to the wanted nodes and check the same length of the pathes and the last or the element before the last for getting the relation.
code :
function getPath(node, value, path = []) {
    if (!node) {
        return;
    }
    if (node.value === value) {
        return path;
    }
    return getPath(node.left, value, path.concat(node.value))
        || getPath(node.right, value, path.concat(node.value));
}

function findRelation(root, a, b) {
    var pathA = getPath(root, a),
        pathB = getPath(root, b);

    if (pathA.length !== pathB.length) {
        return;
    }
    if (pathA.length && pathA[pathA.length - 1] === pathB[pathB.length - 1]) {
        return 'siblings';
    }

    if (pathA.length > 1 && pathA[pathA.length - 2] === pathB[pathB.length - 2]) {
        return 'cousins';
    }
}

var tree = { value: 3, left: { value: 2, left: { value: 1 } }, right: { value: 4, right: { value: 5 } } };

console.log(findRelation(tree, 2, 4));
console.log(findRelation(tree, 1, 5));
