Title
Body
Given the following XML-compliant HTML: <div> <a>a1</a> <b>b1</b> </div> <div> <b>b2</b> </div> <div> <a>a3</a> <b>b3</b> <c>c3</c> </div> doing //a will return: [a1,a3] The problem with above is that the third column data is now in second place, when A is not found it is completely skipped. how can you express an xpath to get all A elements which will return: [a1, null, a3] same case for //c , I wonder if it's possible to get [null, null, c3] UPDATE: consider another scenario where are no common parents <div> . <h1>heading1</h1> <a>a1</a> <b>b1</b> <h1>heading2</h1> <b>b2</b> <h1>heading3</h1> <a>a3</a> <b>b3</b> <c>c3</c> UPDATE: I am now able to use XSLT as well.
