When enabling the RELAXED_ESCAPES option while constructing an XSD regular expression using CL_ABAP_REGEX=>CREATE_XSD, a character sequence x that does not appear in the table above or has no other special meaning will match a literal x. Otherwise, if the RELAXED_ESCAPES option was disabled, such a character sequence x will raise an exception.

.any character except line feed and carriage return
da digit (respecting Unicode character properties)

Quantifiers SyntaxDescription
?0 or 1, greedy
*0 or more, greedy
+1 or more, greedy
{n}exactly n
{n,m}at least n, no more than m, greedy
{n,}n or more, greedy
Lazy quantifiers (also known as reluctant quantifiers) are not supported.

Grouping and Capturing SyntaxDescription
(...)capture group
Technically the concept of capturing groups does not exist in the XSD standard as there are no pure standard means to refer to the content of a group. As the ABAP implementation of XSD regular expressions allows for a PCRE-style replacement syntax, all groups are regarded as capturing.

Alternation SyntaxDescription
|start of alternative branch

Character Classes SyntaxDescription
[...]positive character class
[^...]negative character class
[x-y]range
[a-[b]]character class subtraction (can be nested)

Replacement Syntax
While the XSD standard only defines the match operation for regular expressions, the ABAP implementation also allows all other operations as defined by CL_ABAP_REGEX and CL_ABAP_MATCHER.
The syntax of replacement patterns for XSD regular expressions is the same as for PCRE regular expressions .
