Hi every one,
I am new to xml data files,I have two xml files with same data but only small difference as shown below

Code:

<List>
    <number>1101</number>
  <Area>inner walls in a room.</Area>
  <Detection>less pressure.</Detection>
  <reason>
    <normal>
      <Component Num="15" Type="electric">
        <Beha Num="97" working="yes" acceptrate="100"/>
      </Component>
    </normal>
  </reason>
  <reaction>
    <Informal/>
  </reaction>
  <action>
    <Informal>some data here.
</Informal>
  </action>
</list>

second xml file

Code:

<List>
    <number>1102</number>
  <Area>outer  of  room.</Area>
  <Detection>more pressure.</Detection>
  <reason/>
  <reaction>
    <Informal/>
  </reaction>
  <action/>
</list>

In the above two xml files the difference is in second xml file i Have two empty tag elements One is action and another is reason tags. I created one xsd file file using xmlpad for frist xml file and validated using that xsd , Its giving no errors, but when I tried same xsd for second xml file it giving error like.

Code:

element action{}has invalid structure for schema definition:(informal)

used xsd is like this

Code:

  <xs:element name="Action">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="Informal" minOccures="0"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
<xs:element name="Informal" type="xs:string"/>

same error for reason tags also, I tried in different ways but problem not solved can any one suggest me how to solve this problem.
Thanks in advance.

Your general approach is correct - define minOccurs="0" to make the contained element optional. But the code you have shown us contains basic spelling mistakes, so it can't be your real code. Show us your real code, and the actual error messages, and we should be able to help you.

Hi mhkay,
provided code is not original but the format is same, due to security problems i cant post my original code but it look likes as above code, my problem is in one xml file i have some content in the action tag but in another xml i have empty tag, so how can i solve this problem because already i tried with minOccurs but still problem is there. any more suggestions.
thanks in advance.
