Można użyć MATCH element, aby wymusić wartości w polu typu ciąg wykonaj deseń, który określisz.W przypadku zdefiniowania wielu MATCH elementów, wartość będzie ważne w przypadku, gdy to pokrywa się z wzorców, które określisz dla pola.Jeśli co najmniej jeden element powiedzie się, pole ma prawidłową wartość.

MATCH Element Syntax Structure

You use the MATCH element to enforce basic pattern matching by defining a pattern that values in String type fields must match.

<MATCH pattern="patternValue" for="userGroupName" not="userGroupName" />

Atrybuty

You can specify to which users the MATCH rule applies.If you do not define any optional attributes, all valid users and groups in Team Foundation Server must specify a value that matches the pattern.

Atrybut	Opis
pattern	Wymagane.Enforces basic pattern matching for strings only.Valid values for the patternValue are "A", "N", and "X", which denote the following types of characters: "A" represents an alphabetical character. "N" represents a numeric character. "X" represents any alphanumeric character. All other values are taken as literals.Minimum length: 1; maximum length: 255. Pattern value: ^[^\\]*$ Pattern value example: xxxxx.nn.nn
for	Opcjonalne.Specifies the name of a user or group in Team Foundation to whom the rule applies.Valid names consist of a string of text that contains between 1 and 255 characters. Pattern value: ^[^\\]+\\[^\\]+$ Pattern value example: Domain\UserID
not	Opcjonalne.Specifies the name of a user or group in Team Foundation to whom the rule does not apply.Valid names consist of a string of text that contains between 1 and 255 characters. Pattern value: ^[^\\]+\\[^\\]+$ Pattern value example: Domain\UserID

Pattern value example: xxxxx.nn.nn

for

Opcjonalne.Specifies the name of a user or group in Team Foundation to whom the rule applies.Valid names consist of a string of text that contains between 1 and 255 characters.

Pattern value: ^[^\\]+\\[^\\]+$

Pattern value example: Domain\UserID

not

Opcjonalne.Specifies the name of a user or group in Team Foundation to whom the rule does not apply.Valid names consist of a string of text that contains between 1 and 255 characters.

Pattern Matching Examples

The following examples illustrate successful and unsuccessful pattern matches for a variety of field uses.

Release Number

Pattern: ANN.NN.NN

Validates	R01.03.04 or V05.08.99
Fails validation	1.3.4 or V5.8.99 or v1.3

A Flexible Identifier

Pattern: XXX-XXX

Validates	001-abc or a00-b02
Fails validation	1-abc or 001.abc

Priorytet

Pattern: PN

Validates	P1 or P5 or P9
Fails validation	1 or P10

Match tags are case-insensitive.Therefore, "PN" matches both P1 and p1.
