Aspose::Words::Saving::HtmlSaveOptions::get_DocumentSplitHeadingLevel method

HtmlSaveOptions::get_DocumentSplitHeadingLevel method

Specifies the maximum level of headings at which to split the document. Default value is %2.

int32_t Aspose::Words::Saving::HtmlSaveOptions::get_DocumentSplitHeadingLevel() const

Remarks

When DocumentSplitCriteria includes HeadingParagraph and this property is set to a value from 1 to 9, the document will be split at paragraphs formatted using Heading 1, Heading 2 , Heading 3 etc. styles up to the specified heading level.

By default, only Heading 1 and Heading 2 paragraphs cause the document to be split. Setting this property to zero will cause the document not to be split at heading paragraphs at all.

Examples

Shows how to split an output HTML document by headings into several parts.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);

// Every paragraph that we format using a "Heading" style can serve as a heading.
// Each heading may also have a heading level, determined by the number of its heading style.
// The headings below are of levels 1-3.
builder->get_ParagraphFormat()->set_Style(builder->get_Document()->get_Styles()->idx_get(u"Heading 1"));
builder->Writeln(u"Heading #1");
builder->get_ParagraphFormat()->set_Style(builder->get_Document()->get_Styles()->idx_get(u"Heading 2"));
builder->Writeln(u"Heading #2");
builder->get_ParagraphFormat()->set_Style(builder->get_Document()->get_Styles()->idx_get(u"Heading 3"));
builder->Writeln(u"Heading #3");
builder->get_ParagraphFormat()->set_Style(builder->get_Document()->get_Styles()->idx_get(u"Heading 1"));
builder->Writeln(u"Heading #4");
builder->get_ParagraphFormat()->set_Style(builder->get_Document()->get_Styles()->idx_get(u"Heading 2"));
builder->Writeln(u"Heading #5");
builder->get_ParagraphFormat()->set_Style(builder->get_Document()->get_Styles()->idx_get(u"Heading 3"));
builder->Writeln(u"Heading #6");

// Create a HtmlSaveOptions object and set the split criteria to "HeadingParagraph".
// These criteria will split the document at paragraphs with "Heading" styles into several smaller documents,
// and save each document in a separate HTML file in the local file system.
// We will also set the maximum heading level, which splits the document to 2.
// Saving the document will split it at headings of levels 1 and 2, but not at 3 to 9.
auto options = MakeObject<HtmlSaveOptions>();
options->set_DocumentSplitCriteria(DocumentSplitCriteria::HeadingParagraph);
options->set_DocumentSplitHeadingLevel(2);

// Our document has four headings of levels 1 - 2. One of those headings will not be
// a split point since it is at the beginning of the document.
// The saving operation will split our document at three places, into four smaller documents.
doc->Save(ArtifactsDir + u"HtmlSaveOptions.HeadingLevels.html", options);

doc = MakeObject<Document>(ArtifactsDir + u"HtmlSaveOptions.HeadingLevels.html");

ASSERT_EQ(u"Heading #1", doc->GetText().Trim());

doc = MakeObject<Document>(ArtifactsDir + u"HtmlSaveOptions.HeadingLevels-01.html");

ASSERT_EQ(String(u"Heading #2\r") + u"Heading #3", doc->GetText().Trim());

doc = MakeObject<Document>(ArtifactsDir + u"HtmlSaveOptions.HeadingLevels-02.html");

ASSERT_EQ(u"Heading #4", doc->GetText().Trim());

doc = MakeObject<Document>(ArtifactsDir + u"HtmlSaveOptions.HeadingLevels-03.html");

ASSERT_EQ(String(u"Heading #5\r") + u"Heading #6", doc->GetText().Trim());
