# ChildrenRangeRegex<N>

The `ChildrenRangeRegex<N>` parameter defines part of a document that is split into one or more child documents. The part of the document identified must include the content and all the fields to be extracted into the child documents. This parameter returns the entire document by default.

This parameter accepts one or more regular expressions. The regular expression can contain sub-matches (enclosed in parentheses). If there are multiple matches, the content is concatenated.

For example, to define all content that is enclosed by `<html> </html>` tags, set the parameter to:

    ChildrenRangeRegex0=<html>(.*)</html>
