too many nodes returned from child nodes array property

too many nodes returned from child nodes array property

Hello.

 

I've got some problems with extracting an array of elements (nodes) from a non-labview XML file. It does return an array containing the right elements, but I also get a lot of dummy-elements, which contains no data at all.

 

If I extract all the child nodes of an element by using the 'ChildNodesArray' property on an element which have got n child nodes, I ought to get an n-length array. Instead I get a (n*2)+1-length array, where the first and then every other element is an empty Text_Node and the interleaved elements are Element_Nodes containing the data of the actual child nodes. So for a node with 3 children it ends up something like this:

 

<node>

    <child>value1</child>

    <nextchild>value2</nextchild>

    <nextchild>value3</nextchild>

</node>

 

is converted to the array:

 

[0] Text_Node - no value

[1] Element_Node - value1

[2] Text_Node - no value

[3] Element_Node - value2

[4] Text_Node - no value

[5] Element_Node - value3

[6] Text_Node - no value

 

The values are then available by using the 'Get Node Text Content VI" function on the correct elements. To open the XML file in the first place I use the Load File Method.

 

It all seems rather unnecessary.

Re: too many nodes returned from child nodes array property

Hi!

The fake text nodes you see are probably due to end of line characters.

 

Try this:

removing all end of line characters you get only the 3 nodes you are looking for.
