Add(CustomXmlPart)

Adds an item to the collection.

public void Add(CustomXmlPart part)
ParameterTypeDescription
partCustomXmlPartThe custom XML part to add.

Examples

Shows how to create a structured document tag with custom XML data.

Document doc = new Document();

// If we enable the "Developer" tab in Microsoft Word,
// we can find elements from this collection in the "XML Mapping Pane", along with a few default elements.

Assert.AreEqual(xmlPartId, xmlPart.Id);

// Below are two ways to refer to XML parts.
// 1 -  By an index in the custom XML part collection:
Assert.AreEqual(xmlPart, doc.CustomXmlParts[0]);

// Add an XML schema association.
xmlPart.Schemas.Add("http://www.w3.org/2001/XMLSchema");

// Clone a part, and then insert it into the collection.

        Console.WriteLine($"\tContent: {Encoding.UTF8.GetString(enumerator.Current.Data)}");
        index++;
    }
}

// Use the "RemoveAt" method to remove the cloned part by index.
doc.CustomXmlParts.RemoveAt(1);

// Clone the XML parts collection, and then use the "Clear" method to remove all its elements at once.

customXmlParts.Clear();

// Create a structured document tag that will display our part's contents and insert it into the document body.
