Aspose::Words::Markup::CustomXmlPartCollection class

CustomXmlPartCollection class

Represents a collection of Custom XML Parts. The items are CustomXmlPart objects. To learn more, visit the Structured Document Tags or Content Control documentation article.

class CustomXmlPartCollection : public System::Collections::Generic::IEnumerable<System::SharedPtr<Aspose::Words::Markup::CustomXmlPart>>

Remarks

You do not normally need to create instances of this class. You can access custom XML data stored in a document via the CustomXmlParts property.

Examples

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

auto doc = System::MakeObject<Aspose::Words::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,
// we can find elements from this collection in the "XML Mapping Pane", along with a few default elements.
System::String xmlPartId = System::Guid::NewGuid().ToString(u"B");
System::String xmlPartContent = u"<root><text>Hello world!</text></root>";
System::SharedPtr<Aspose::Words::Markup::CustomXmlPart> xmlPart = doc->get_CustomXmlParts()->Add(xmlPartId, xmlPartContent);

ASPOSE_ASSERT_EQ(System::Text::Encoding::get_ASCII()->GetBytes(xmlPartContent), xmlPart->get_Data());
ASSERT_EQ(xmlPartId, xmlPart->get_Id());

// Below are two ways to refer to XML parts.
// 1 -  By an index in the custom XML part collection:
ASPOSE_ASSERT_EQ(xmlPart, doc->get_CustomXmlParts()->idx_get(0));

// 2 -  By GUID:
ASPOSE_ASSERT_EQ(xmlPart, doc->get_CustomXmlParts()->GetById(xmlPartId));

// Add an XML schema association.
xmlPart->get_Schemas()->Add(u"http://www.w3.org/2001/XMLSchema");

// Clone a part, and then insert it into the collection.
System::SharedPtr<Aspose::Words::Markup::CustomXmlPart> xmlPartClone = xmlPart->Clone();
xmlPartClone->set_Id(System::Guid::NewGuid().ToString(u"B"));
doc->get_CustomXmlParts()->Add(xmlPartClone);

ASSERT_EQ(2, doc->get_CustomXmlParts()->get_Count());

// Iterate through the collection and print the contents of each part.
{
    System::SharedPtr<System::Collections::Generic::IEnumerator<System::SharedPtr<Aspose::Words::Markup::CustomXmlPart>>> enumerator = doc->get_CustomXmlParts()->GetEnumerator();
    int32_t index = 0;
    while (enumerator->MoveNext())
    {
        std::cout << System::String::Format(u"XML part index {0}, ID: {1}", index, enumerator->get_Current()->get_Id()) << std::endl;
        std::cout << System::String::Format(u"\tContent: {0}", System::Text::Encoding::get_UTF8()->GetString(enumerator->get_Current()->get_Data())) << std::endl;
        index++;
    }
}

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

ASSERT_EQ(1, doc->get_CustomXmlParts()->get_Count());

// Clone the XML parts collection, and then use the "Clear" method to remove all its elements at once.
System::SharedPtr<Aspose::Words::Markup::CustomXmlPartCollection> customXmlParts = doc->get_CustomXmlParts()->Clone();
customXmlParts->Clear();

// Create a structured document tag that will display our part's contents and insert it into the document body.
auto tag = System::MakeObject<Aspose::Words::Markup::StructuredDocumentTag>(doc, Aspose::Words::Markup::SdtType::PlainText, Aspose::Words::Markup::MarkupLevel::Block);
tag->get_XmlMapping()->SetMapping(xmlPart, u"/root[1]/text[1]", System::String::Empty);

doc->get_FirstSection()->get_Body()->AppendChild<System::SharedPtr<Aspose::Words::Markup::StructuredDocumentTag>>(tag);

doc->Save(get_ArtifactsDir() + u"StructuredDocumentTag.CustomXml.docx");
