I would like to remove consecutive duplicate node from the same parent and which also has exact same children.Input Scenario 1:\[code\]<myroot> <nodeA id="a"> <section id="i"> <item1 id="0" method="create"> <somechild>a</somechild> </item1> <item1 id="1" method="create"> <otherchild>a</otherchild> </item1> </section> <section id="i"> <item1 id="0" method="create"> <!-- second consecutive create, we remove this --> <somechild>a</somechild> </item1> <item1 id="0" method="create"> <!-- third consecutive create, but children have different value , so we don't remove this --> <somechild>bbb</somechild> </item1> <item1 id="3" method="create"> <other>xx</other> </item1> <item1 id="0" method="change"> <otherchild>a</otherchild> </item1> </section> </nodeA> <nodeA id="b"> <section id="i"> <item1 id="0" method="create"> <somechild>a</somechild> </item1> <item1 id="1" method="create"> <otherchild>a</otherchild> </item1> </section> <section id="i"> <item1 id="0" method="create"> <!-- second consecutive create, we remove this --> <somechild>a</somechild> </item1> <item1 id="0" method="create"> <!-- third consecutive create, but children have different value , so we don't remove this --> <somechild>bbb</somechild> </item1> <item1 id="3" method="create"> <other>xx</other> </item1> <item1 id="0" method="change"> <otherchild>a</otherchild> </item1> </section> </nodeA> <nodeB id="b"> <section id="i"> <item1 id="0" method="create"> <somechild>a</somechild> </item1> <item1 id="1" method="create"> <otherchild>a</otherchild> </item1> </section> <section id="i"> <item1 id="0" method="create"> <!-- second consecutive create, we remove this --> <somechild>a</somechild> </item1> <item1 id="0" method="create"> <!-- third consecutive create, but children have different value , so we don't remove this --> <somechild>bbb</somechild> </item1> <item1 id="3" method="create"> <other>xx</other> </item1> <item1 id="0" method="change"> <otherchild>a</otherchild> </item1> </section> </nodeB></myroot>\[/code\]My result:\[code\]<myroot> <nodeA id="a"> <section id="i"> <item1 id="0" method="create"> <somechild>a</somechild> </item1> <item1 id="1" method="create"> <otherchild>a</otherchild> </item1> </section> <section id="i"> <item1 id="0" method="create"> <somechild>bbb</somechild> </item1> <item1 id="3" method="create"> <other>xx</other> </item1> <item1 id="0" method="change"> <otherchild>a</otherchild> </item1> </section> </nodeA> <nodeA id="b"> <section id="i"/> <section id="i"/> </nodeA> <nodeB id="b"> <section id="i"/> <section id="i"/> </nodeB></myroot>\[/code\]Expected Output:\[code\]<myroot> <nodeA id="a"> <section id="i"> <item1 id="0" method="create"> <somechild>a</somechild> </item1> <item1 id="1" method="create"> <otherchild>a</otherchild> </item1> </section> <section id="i"> <item1 id="0" method="create"> <somechild>bbb</somechild> </item1> <item1 id="3" method="create"> <other>xx</other> </item1> <item1 id="0" method="change"> <otherchild>a</otherchild> </item1> </section> </nodeA> <nodeA id="b"> <section id="i"> <item1 id="0" method="create"> <somechild>a</somechild> </item1> <item1 id="1" method="create"> <otherchild>a</otherchild> </item1> </section> <section id="i"> <item1 id="0" method="create"> <somechild>bbb</somechild> </item1> <item1 id="3" method="create"> <other>xx</other> </item1> <item1 id="0" method="change"> <otherchild>a</otherchild> </item1> </section> </nodeA> <nodeB id="b"> <section id="i"> <item1 id="0" method="create"> <somechild>a</somechild> </item1> <item1 id="1" method="create"> <otherchild>a</otherchild> </item1> </section> <section id="i"> <item1 id="0" method="create"> <somechild>bbb</somechild> </item1> <item1 id="3" method="create"> <other>xx</other> </item1> <item1 id="0" method="change"> <otherchild>a</otherchild> </item1> </section> </nodeB></myroot>\[/code\]In the first scenario above: only the second consecutive create has the same children and the third consecutive \[code\]create\[/code\] method has different children that's why we only remove the second one.
