Finding the position of an element

To find the position of element <b>col_d</b> in the following xml:

1 2 3 4 5 6 7

<a> <b>col_a</b> <b>col_b</b> <b>col_c</b> <b>col_d</b> <b>col_e</b> </a>

U can probably use the following xpath:

count(//b[normalize-space(text())="col_d"]/preceding-sibling::b)+1

But it doesn't work for me in nokogiri, so what i did was:

1 2	doc = Nokogiri::XML(above_xml_string) doc.xpath('//b[normalize-space(text())="col_d"]/preceding-sibling::b').count + 1

That's all !!
