SpreadsheetML Reference Material - Table of Contents

xmlColumnPr (XML Column Properties)

An element defining the XML column properties for a column. This is only used for tables created from XML mappings.

[Example: Here is a simple example showing a table column that has an xmlColumPr.

<tableColumn id="1" uniqueName="SomeElement" name="SomeElement">
<xmlColumnPr mapId="1" xpath="/xml/foo/element" xmlDataType="string"/>

end example]

Parent Elements



Child Elements


extLst (Future Feature Data Storage Area)





denormalized (Denormalized)

A Boolean that indicates whether the contents of the column have been filled down due to flattening. True if it has been filled down (denormilized), false otherwise.


This should be used when an XML mapping parent value has many children, and both the parent and child fields are mapped to their own column in the table.



<Order ID="3">


The resulting table in the spreadsheet application would have two columns, the first with the item ID, filled down for each item in the table as follows:


Item ID Item

3 Milk

3 Bread

3 Cheese


end example]


The possible values for this attribute are defined by the XML Schema boolean datatype.

mapId (XML Map Id)

An integer representing the ID of the XML map this table field is associated with.


The XML map will be defined in the xml maps part, and the Map element should have the corresponding id.


The possible values for this attribute are defined by the XML Schema unsignedInt datatype.

xmlDataType (XML Data Type)

An enumeration indicating which XML data type is used by this column.


The possible values for this attribute are defined by the ST_XmlDataType simple type (§3.18.95).

xpath (XPath)

A string representing the XML path to the element this column is associated with.


The spreadsheet application should support XPath limited to the following

The XPath is an absolute path to a simple-content element or attribute


"/ns1:root/ns1:row/ns1:column1" is supported if 'column1' is a child-most node, but not "/ns1:root/ns1:row" for the same document since 'row' is not a child.

end example]


The XPath does not express axes, but uses the default child axes


"/ns1:root/ns1:row" is supported but not "/ns1:root/child::ns1:row

end example]


An optional filter can be expressed at the end of the xpath


"/ns1:root/ns1:row/ns1:column1[@foo='abc']" is supported but not "/ns1:root/ns1:row[@foo='abc']/ns1:column1"

end example]


The filter can only contain a single expression comparing a named attribute to a specific value

Filters are only supported on XPaths that resolve to a simple-content element (not attributes)

The named attribute must be defined as an attribute of the simple-content element

The attribute name must be preceded by the short-hand (@) symbol representing the axes 'attribute'


"/ns1:root/ns1:row/ns1:column1[@foo='abc']" is supported not "/ns1:root/ns1:row/ns1:column1[attribute::foo='abc']"

end example]


An arbitrary amount of white-space can be embedded between filter tokens


"/ns1:root/ns1:row/ns1:column1[ @ foo='abc']" is valid

end example]


The possible values for this attribute are defined by the ST_Xstring simple type (§3.18.96).

The following XML Schema fragment defines the contents of this element:

<complexType name="CT_XmlColumnPr">


   <element name="extLst" type="CT_ExtensionList" minOccurs="0" maxOccurs="1"/>


   <attribute name="mapId" type="xsd:unsignedInt" use="required"/>

   <attribute name="xpath" type="ST_Xstring" use="required"/>

   <attribute name="denormalized" type="xsd:boolean" use="optional" default="false"/>

   <attribute name="xmlDataType" type="ST_XmlDataType" use="required"/>
