The element type xs:element must be terminated by the matching end-tag </xs:element>

Question

I have an error message on my XML Schema. To start, here is my XML file:

<?xml version="1.0" encoding="UTF-8"?>
<customer xmlns:xsi="http:www.w3.org/2001/XMLSchema"
    xsi:noNamespaceSchemaLocation="customer.xsd">
    <name>
        <first>Bob</first>
        <MI>H</MI>
        <last>Jones</last>
    </name>
    <cnum>007389</cnum>
    <mail_a>
        <line1>12345 Mockingbird Lane</line1>
        <city>Omaha</city>
        <state>NE</state>
        <zip>68123</zip>
        <country>USA</country>
    </mail_a>
    <deliver_a>
        <line1>12345 Mockingbird Lane</line1>
        <city>Omaha</city>
        <state>NE</state>
        <zip>68123</zip>
        <country>USA</country>
    </deliver_a>
    <member_date>1995-10-15</member_date>
    <l_order_date>2003-08-02</l_order_date>
</customer>

And here is my schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:element name="customer"/>
  <xs:complexType>
    <xs:sequence>
      <xs:element ref="name"/>
      <xs:element ref="cnum"/>
      <xs:element ref="mail_a"/>
      <xs:element ref="deliver_a"/>
      <xs:element ref="member_date"/>
      <xs:element ref="l_order_date"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

<xs:element name="first" type="xs:string"/>
<xs:element name="MI" type="xs:string"/>
<xs:element name="last" type="xs:string"/>
<xs:element name="cnum" type="xs:integer"/>

<xs:element name="city" type="xs:string"/>
<xs:element name="state" type="xs:string"/>
<xs:element name="zip" type="xs:integer"/>
<xs:element name="country" type="xs:string"/>
<xs:element name="member_date" type="xs:date"/>
<xs:element name="l_order_date" type="xs:date"/>

<xs:element name="name">
  <xs:complexType>
    <xs:sequence>
      <xs:element ref="first"/>
      <xs:element ref="MI"/>
      <xs:element ref="last"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

 <xs:element name="mail_a">
  <xs:complexType>
    <xs:sequence>
      <xs:element ref="line1"/>
      <xs:element ref="city"/>
      <xs:element ref="state"/>
      <xs:element ref="zip"/>
        <xs:element ref="country"/>
    </xs:sequence>
  </xs:complexType>
 </xs:element>


<xs:element name="deliver_a">
  <xs:complexType>
    <xs:sequence>
      <xs:element ref="line1"/>
      <xs:element ref="city"/>
      <xs:element ref="state"/>
      <xs:element ref="zip"/>
      <xs:element ref="country"/>
    </xs:sequence>
  </xs:complexType>
 </xs:element>
</xs:schema>

The error that I'm getting is

The element type xs:element must be terminated by the matching end-tag </xs:element>

It appears that it doesn't like line 55 for some reason (element ref="line1"), which has a closing tag on it.

The XML file says that I'm missing the xs:schema end tag. Well, there it is... The editor that I'm using is oXygen.

Any thoughts? I've been fiddling around with it forever.

Answer 1

In addition to the premature closing of the customer element declaration that @randominstanceOfLivingThing mentioned, you must change

xmlns:xsi="http:www.w3.org/2001/XMLSchema"

to

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

in your XML, then your XSD will be found and your XML will validate successfully.

Here are the entire, corrected XML and XSD files:

Answer 2

Immediately after the schema declaration you closed the customer element:

Incorrect schema element:

    <xs:element name="customer"/>
    <xs:complexType>
        <xs:sequence>
            <xs:element ref="name"/>
            <xs:element ref="cnum"/>
            <xs:element ref="mail_a"/>
            <xs:element ref="deliver_a"/>
            <xs:element ref="member_date"/>
            <xs:element ref="l_order_date"/>
        </xs:sequence>
    </xs:complexType>
    </xs:element>

Correct schema element:

    <xs:element name="customer">
    <xs:complexType>
        <xs:sequence>
            <xs:element ref="name"/>
            <xs:element ref="cnum"/>
            <xs:element ref="mail_a"/>
            <xs:element ref="deliver_a"/>
            <xs:element ref="member_date"/>
            <xs:element ref="l_order_date"/>
        </xs:sequence>
    </xs:complexType>
    </xs:element>
