xml parsing - Can a XML element contain text and child elements at the same time?

Question

I was looking at some xml files but didn't find the answer to my question: Can a XML element contain text and child elements at the same time?

For example:

<tree>
    <node1> 
      textTextText 
      <subnode1> text1 </subnode1>
      <subnode2> text2 </subnode2>
    </node1>
</tree>

I always see these kinds:

    <node2>
       <sub1> text </sub1>
    </node2>

Answer 1

Yes. A parent node contains zero or more child nodes. Text nodes and element nodes are two kinds of nodes and an element node can have any number of text and/or element child nodes in any order. Schemas might restrict this, though. In fact, the whitespace between element nodes actually forms text node siblings. Usually this whitespace is ignored, though.
