Tracked content

Use XPath to define tracked parts of page.

• Block wrapper - main wrapper of tracked block
• Content ID - unique part inside of wrapper which will be used as identifier for tracked record, that means that any other record with same value will be skipped
• Content unique ID context
  • global - ID is checked against all records (e.g. if you use multiple trackers for one domain)
  • website - ID is checked only against other website's IDs
• Content item # - content parts that will be used in notification message
• Default content item # - placeholder for missing item

Example:

<div class="news">
    <span class="label">NEW!</span>
    <a href="http://www.news.com/lorem-ipsum"><h2>Lorem ipsum!</h2></a>

    <img src="http://img.news.com/lorem-ipsum.jpg" />

    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip...</p>

    <a href="http://www.news.com/lorem-ipsum">Read more</a>
</div>

In this example, block wrapper is <div class="news"> and unique ID can be post's URL.

Variable	Value	Result
Block wrapper	//div[@class="news"]	-
Content ID	/a[1]/@href	http://www.news.com/lorem-ipsum
Content item 1	/a[1]/h2	Lorem ipsum!
Content item 2	/p[1]	Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip...
Content item 3	/img[1]/@src	http://img.news.com/lorem-ipsum.jpg
