I have checked the documentation; I found a method to set text of of struct elements. Is there any method to extract text of struct elements. I have seen a method to extract actualtext but my objective is to extract text of struct elements along with tag.
Example: If there ia a tag H1 and text Heading 1 in a tagged PDF, can you let me know how this can be achieved using Aspose.PDF

You can access and get the Tag as well as Actual Text using below properties:

string tag = structureElement.StructureType.Tag;
string actualText = structureElement.ActualText;

Complete Code:

// Open Pdf Document
Document document = new Document(dataDir + "StructureElementsTree.pdf");

// Get Content for work with TaggedPdf
ITaggedContent taggedContent = document.TaggedContent;

// Access to root element(s)
ElementList elementList = taggedContent.StructTreeRootElement.ChildElements;
foreach (Element element in elementList)
{
    if (element is StructureElement)
    {
        StructureElement structureElement = element as StructureElement;

        // Get properties
        string title = structureElement.Title;
        string language = structureElement.Language;
        string actualText = structureElement.ActualText;
        string expansionText = structureElement.ExpansionText;
        string alternativeText = structureElement.AlternativeText;
    }
}

// Access to child elements of first element in root element
elementList = taggedContent.RootElement.ChildElements[1].ChildElements;
foreach (Element element in elementList)
{
    if (element is StructureElement)
    {
        StructureElement structureElement = element as StructureElement;

        // Set properties
        structureElement.Title = "title";
        structureElement.Language = "fr-FR";
        structureElement.ActualText = "actual text";
        structureElement.ExpansionText = "exp";
        structureElement.AlternativeText = "alt";
        // Get Properties
        string tag = structureElement.StructureType.Tag;
        string actualText = structureElement.ActualText;
    }
}
