Scanning data attributes

Sitemap Creator has a fixed set of rules which govern how it crawls a document such as a HTML page or style sheet for additional resources. With the rise of responsive websites, these default rules might not always be sufficient - for example custom data attributes may be applied to the img tag in order to support retina images. Sitemap Creator allows you to specify additional attributes to scan, either by using simple names or more complex XPath expressions.

To scan custom attributes for links to other resources

1. From the Project Properties dialogue, expand the Advanced category and select Custom Attributes
2. In the edit field, enter each additional custom attribute you wish to scan

For more advanced scenarios, you can use XPath expressions. For example, if a document contained a p tag and an img tag, each with a custom attribute named data-original, you can scan only those on the img tag by using the expression //img/@data-original.
