This attribute defines what levels of the source tree should be considered when numbering elements. The three valid values for this attribute are
Counts items at one level only. The XSLT processor goes to the first node in the
ancestor-or-selfaxis that matches the

Counts items at multiple levels. The XSLT processor looks at all ancestors of the current node and the current node itself, then it selects all of those nodes that match the
Includes all of the current node’s ancestors (as
level="multiple"does) as well as all elements in the
In all of these cases, if the
fromattribute is used, the only ancestors that are examined are descendants of the nearest ancestor that matches the
fromattribute. In other words, with
from="h1", the only nodes considered for counting are those that appear under the nearest
fromattribute is an XPath expression that defines where counting starts. For example, you can use the
fromattribute to say that counting should begin at the previous
