Subject: [xsl] What does //distinct-values(...) mean? From: "Costello, Roger L. costello@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Wed, 8 Apr 2020 12:18:50 -0000 |
Hi Folks, I executed this XPath query in Oxygen: //distinct-values(//Row[matches(Advertiser, 'TS3', 'i')]/Subscribers) The two slashes at the beginning were an accident. At the bottom of the screen Oxygen shows the matches. All of a sudden it showed 111,000 matches, then a moment later 438,000 matches, and then finally 525,946 matches. "Yikes!" I thought, "What is going on? There is supposed to be around 17 matches. How can there be half a million matches?" Then I saw the two slashes at the start. "Hmm, what is the meaning of two slashes preceding the distinct-values function?" I thought. So, I ask you: what is the meaning of two slashes preceding the distinct-values function? Why does its evaluation result in so many matches? /Roger
