XPath count() function

xml, xpath

Solution

Title with one author:

/proceedings/contents/article[count(author)=1]/title

Number of articles with more than three authors:

count(/proceedings/contents/article[count(author)>3])

Problem

Suppose I have an XML tree as below: ``` proceedings -name -contents -article -author -title -pages ``` How can I identify any title that has only one author? And the number of articles that have more than three author using XPath?
