Hi,

One of my pattern matching validation attribute failed without understandeable reason:

The following schema is used :

Code: Select all


....

	<xd:simpleType name="t_no.oj">

		<xd:restriction base="xd:string">

			<xd:pattern value="\d{1,3}(A|E){0,1}"/>

		</xd:restriction>

	</xd:simpleType>

....

                                 <xd:element ref="NO.OJ" minOccurs="0"/>

....

	<xd:element name="NO.OJ" type="t_no.oj"/>

....

The following instance extract is refused :

Code: Select all




<NO.OJ>876</NO.OJ>

My environment seems to be correct :

Windows 2000 workstation

Code: Select all


java version "1.4.1_02"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06)

Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)

Best,

Dear Pierre,

The schema snippet you posted cannot be validated so I changed it as follows:

Code: Select all


<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:simpleType name="t_no.oj">

        <xs:restriction base="xs:string">

            <xs:pattern value="\d{1,3}(A|E){0,1}"/>

        </xs:restriction>

    </xs:simpleType>

    <xs:element name="NO.OJ" type="t_no.oj"/>

</xs:schema>

If you name this as sample.xsd and in the same directory create an XML file with the following content:

Code: Select all


<?xml version="1.0" encoding="UTF-8"?>

<NO.OJ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="sample.xsd">876</NO.OJ>

the validation check will report no errors.

If you still have problems please post the exact sample files you are using.

Best Regards,
George

Dear George,

Thank you for your endevour. I finally found the problem origin.
The pattern matching is correct but the apparence is well described in the previous post. The reason is simple. UTF-8 Hidden characters exist between <NO.OJ> and 876. With the oxygen editor, I didn't see them. The illegal characters were in hexadecimal EF BB BF.

Is it anyway to view special or hidden characters ?

Best regards,

Pierre

Hi Pierre,

There is no way currently to view special characters. We will provide support for this in the next version.

Best Regards,
George
