XPath Search Syntex {Resolved}

[wrack]

Hi

Give the XML Schema provided here, how can I search for complexType where the name attribute's value is "OptTmsTimesheetEntry"

I have this XPath Syntex but it's not working...???

  FXmlSchema : IXmlDocument;
  aSelectNode : IDOMNodeSelect;
  aNode : IDOMNode;
  iRootNode: IXMlNode;

  FXmlSchema := LoadXMLDocument(XmlSchemaLocation);

  iRootNode := FXmlSchema.DocumentElement;

  aSelectNode := FXmlSchema.DOMDocument.documentElement as IDOMNodeSelect ;

  aNode := aSelectNode.selectNode('complexType[@name = "OptTmsTimesheetEntry"]');

I also tried this...

aNode := aSelectNode.selectNode('/xs:schema/xs:complexType/[@name = "OptTmsTimesheetEntry"]');

Any suggestions...?

A similar query in VB would be

Set oxmlNodeList = XSDDoc.documentElement _
                            .selectNodes("xsd:complexType[@name='classdescType']")

Thank you martin but I am getting an error.

"Reference to an undeclared prefix 'xsd' "

what do u make out of it...?

[MartinLiss]

I'm not a schema expert, but the schema that that code assumes looks like this

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
	<xsd:element name="kb">
		<xsd:annotation>
			<xsd:documentation>Root element of each Pact Knowledge Base</xsd:documentation>
		</xsd:annotation>
		<xsd:complexType>
			<xsd:sequence>
				<xsd:element name="class" type="classType" minOccurs="0" maxOccurs="unbounded">
					<xsd:annotation>
						<xsd:documentation>A class represents a single PACT object</xsd:documentation>
					</xsd:annotation>
					<xsd:unique name="Attrib_Name_Unique">
						<xsd:selector xpath="attrib"/>
						<xsd:field xpath="@name"/>
					</xsd:unique>
				</xsd:element>
				<xsd:element name="resource" type="resourceType" minOccurs="0" maxOccurs="unbounded"/>
			</xsd:sequence>
			<xsd:attribute name="kb-id" type="xsd:string" use="required"/>
			<xsd:attribute name="kb-version" type="xsd:string" use="required"/>
		</xsd:complexType>

Well my schema is same as urs but I have xs: instead of xsd: everything else is same.

Am I using correct type of data types to declare variables...???

[MartinLiss]

Then I would use xs:

My var is defined this way

Dim oxmlNodeList As IXMLDOMNodeList

[wrack]

can you please tell me the type of XSDDOC variable you have declared...?

[MartinLiss]

Public XSDDoc As MSXML2.DOMDocument40

The 40 is because I use MSXML4.

[wrack]

I think I am getting closer to solve this. Thank Matrin.

more question.

how do u load the schema into DOMDocument40 variable ...?

[MartinLiss]

XSDDoc.Load strSchemaPathAndName

[wrack]

Cool thanks Martin.

Now I am stuck in another problem. I suppose that you don't work with Delphi. Do you...?

[MartinLiss]

No, sorry.

[wrack]

No worries. Thanks for all ur input. I atleast came to right track. I was using wrong type of variables now I am using the correct one. Just a matter of figuring it out what I did wrong.

[MartinLiss]

I don't do Delphi but what problem are you having?

[wrack]

Access violation. That happens when some variable is set to nothing and I try to access it but in this case I am sure that it exists and I can see a pointer to it.

DOH: DOH: DOH:

I was using LoadXML method to load Schema and it was expecting schema file as a string not as it's location and name so all after that went to drain.

I was so desperate to make it work that I missed what u said Martin. Thanks for all ur help.

Cheers.
