public CustomXmlPart()

public byte[] getData() / public void setData(byte[] value)

Gets or sets the XML content of this Custom XML Data Storage Part.

The default value is an empty byte array. The value cannot be null.

public long getDataChecksum()

Specifies a cyclic redundancy check (CRC) checksum of the Data content.

Example:

Shows how the checksum is calculated in a runtime.

Document doc = new Document();

StructuredDocumentTag richText = new StructuredDocumentTag(doc, SdtType.RICH_TEXT, MarkupLevel.BLOCK);
doc.getFirstSection().getBody().appendChild(richText);

// The checksum is read-only and computed using the data of the corresponding custom XML data part.
richText.getXmlMapping().setMapping(doc.getCustomXmlParts().add(UUID.randomUUID().toString(),
        "<root><text>ContentControl</text></root>"), "/root/text", "");

long checksum = richText.getXmlMapping().getCustomXmlPart().getDataChecksum();
System.out.println(checksum);

richText.getXmlMapping().setMapping(doc.getCustomXmlParts().add(UUID.randomUUID().toString(),
        "<root><text>Updated ContentControl</text></root>"), "/root/text", "");

long updatedChecksum = richText.getXmlMapping().getCustomXmlPart().getDataChecksum();
System.out.println(updatedChecksum);

// We changed the XmlPart of the tag, and the checksum was updated at runtime.
Assert.assertNotEquals(checksum, updatedChecksum);

public java.lang.String getId() / public void setId(java.lang.String value)

Gets or sets the string that identifies this custom XML part within an OOXML document.

ISO/IEC 29500 specifies that this value is a GUID, but old versions of Microsoft Word allowed any string here. Aspose.Words does the same for ECMA-376 format. But note, that Microsoft Word Online fails to open a document created with a non-GUID value. So, a GUID is preferred value for this property.

A valid value must be an identifier that is unique among all custom XML data parts in this document.

The default value is an empty string. The value cannot be null.

Example:

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

Document doc = new Document();

// Construct an XML part that contains data and add it to the document's collection.
// If we enable the "Developer" tab in Microsoft Word,
