Guest eleven Posted October 21, 2006 Share Posted October 21, 2006 Hi all,I am a newbie to XML and have been trying to learn how to use schema to validate my entries. Can anyone try to help me spot what is wrong with my XSD because it keeps having error? I am not sure if I have used it correctly. Thank you for your help.My XML Doc<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="vehicles.xsl" ?><vehicle> <car> <reg>1FTN-707</reg> <date>2006-07-28</date> <start>10001</start> <end>10010</end> <id>101786J</id> <purpose>demo</purpose> <fuel>20.5</fuel> <cost>31</cost> </car> <car> <reg>1FTN-707</reg> <date>2006-07-28</date> <start>10010</start> <end>10015</end> <id>101786J</id> <purpose>demo</purpose> </car> <car> <reg>1FTN-707</reg> <date>2006-07-27</date> <start>9100</start> <end>10001</end> <id>101786J</id> <purpose>seminar</purpose> <fuel>95</fuel> <cost>133</cost> </car> <car> <reg>1CBL-099</reg> <date>2006-07-02</date> <start>1001</start> <end>1050</end> <id>195767B</id> <purpose>to conference</purpose> </car> <car> <reg>1CBL-099</reg> <date>2006-07-02</date> <start>1050</start> <end>1100</end> <id>195767B</id> <purpose>from conference</purpose> </car> <car> <reg>1CBL-099</reg> <date>2006-07-03</date> <start>1100</start> <end>1500</end> <id>195767B</id> <purpose>Customer tour</purpose> <fuel>80</fuel> <cost>120</cost> </car> <car> <reg>1ADA-095</reg> <date>2006-07-10</date> <start>27675</start> <end>27700</end> <id>234100K</id> <purpose>private</purpose> </car> <car> <reg>1ADA-095</reg> <date>2006-07-11</date> <start>27700</start> <end>27710</end> <id>234100K</id> <purpose>private</purpose> </car> <car> <reg>1ADA-095</reg> <date>2006-07-11</date> <start>27710</start> <end>27730</end> <id>234100K</id> <purpose>private</purpose> <fuel>50</fuel> <cost>70.5</cost> </car> <car> <reg>1CPP-101</reg> <date>2006-07-21</date> <start>30054</start> <end>30090</end> <id>101001A</id> <purpose>Service call</purpose> <fuel>25.5</fuel> <cost>32.3</cost> </car> <car> <reg>1BSC-303</reg> <date>2006-07-09</date> <start>45171</start> <end>45221</end> <id>100101B</id> <purpose>Test drive</purpose> </car> <car> <reg>1BSC-303</reg> <date>2006-07-10</date> <start>45221</start> <end>45250</end> <id>100101B</id> <purpose>Car service</purpose> </car> <car> <reg>1BSC-303</reg> <date>2006-07-11</date> <start>45250</start> <end>45300</end> <id>100101B</id> <purpose>private</purpose> </car> <car> <reg>1BSC-303</reg> <date>2006-07-11</date> <start>45300</start> <end>45375</end> <id>100101B</id> <purpose>demo</purpose> <fuel>60</fuel> <cost>75.5</cost> </car> <car> <reg>1BSC-303</reg> <date>2006-07-11</date> <start>45375</start> <end>45420</end> <id>100101B</id> <purpose>Service call</purpose> </car></vehicle>My XSD<?xml version="1.0" encoding="utf-8"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"><xs:element name="vehicle"><xs:complexType><xs:sequence><xs:element ref="car" maxOccurs="unbounded" /></xs:sequence></xs:complexType></xs:element><xs:element name="car"><xs:complexType><xs:sequence><xs:element ref="reg"/><xs:element ref="date"/><xs:element ref="start"/><xs:element ref="end"/><xs:element ref="id"/><xs:element ref="purpose"/><xs:element ref="fuel" minOccurs="0"/><xs:element ref="cost" minOccurs="0"/></xs:sequence></xs:complexType></xs:element><xs:element name="reg"><xs:simpleType><xs:restriction base="xs:string"><xs:pattern value="1[a-z][a-z][a-z]-[0-9][0-9][0-9]"/></xs:restriction></xs:simpleType></xs:element><xs:element name="date" type="xs:gYear"/><xs:element name="start" type="xs:integer"/><xs:element name="end" type="xs:integer" /><xs:element name="id"><xs:simpleType><xs:restriction base="xs:string"><xs:pattern value="[0-9][0-9][0-9][0-9][0-9][0-9][a-z]" /></xs:restriction></xs:simpleType></xs:element><xs:element name="purpose" type="xs:string"/><xs:element name="fuel" type="xs:decimal" /><xs:element name="cost" type="xs:decimal" /></xs:schema> Link to comment Share on other sites More sharing options...
boen_robot Posted October 22, 2006 Share Posted October 22, 2006 Regular expressions are case sencetive. So [a-z] is different then [A-Z]. If you want to allow both lower case and upper case letters, you need to use [A-Za-z].Also, your <date> element contains a whole date, not only years, so you need to use xs:date for it instead of xs:gYear.Last, but not least. Try to shorten repeating patterns. Instead of writing [0-9][0-9][0-9][0-9][0-9][0-9], you could write [0-9]{6,6}. The first digit in the parenthesis means the minimum amount of times the previous character (in this case: a number from 0 to 9) must appear, and the second is the maxumum number of times. You may omit the comma and/or any of the numbers, but that doesn't work with all validators. The above way works in every validator that supports parenthesis.
