Examples

Shows how to trim whitespace when loading plaintext documents.

System::String textDoc = System::String(u"      Line 1 \n") + u"    Line 2   \n" + u" Line 3       ";

// Create a "TxtLoadOptions" object, which we can pass to a document's constructor
// to modify how we load a plaintext document.
auto loadOptions = System::MakeObject<Aspose::Words::Loading::TxtLoadOptions>();

// Set the "LeadingSpacesOptions" property to "TxtLeadingSpacesOptions.Preserve"
// to preserve all whitespace characters at the start of every line.
// Set the "LeadingSpacesOptions" property to "TxtLeadingSpacesOptions.ConvertToIndent"
// to remove all whitespace characters from the start of every line,
// and then apply a left first line indent to the paragraph to simulate the effect of the whitespaces.
// Set the "LeadingSpacesOptions" property to "TxtLeadingSpacesOptions.Trim"
// to remove all whitespace characters from every line's start.
loadOptions->set_LeadingSpacesOptions(txtLeadingSpacesOptions);

// Set the "TrailingSpacesOptions" property to "TxtTrailingSpacesOptions.Preserve"
// to preserve all whitespace characters at the end of every line.
// Set the "TrailingSpacesOptions" property to "TxtTrailingSpacesOptions.Trim" to
// remove all whitespace characters from the end of every line.
loadOptions->set_TrailingSpacesOptions(txtTrailingSpacesOptions);
