Aspose::Words::Replacing::ReplacingArgs::get_MatchNode method

ReplacingArgs::get_MatchNode method

Gets the node that contains the beginning of the match.

System::SharedPtr<Aspose::Words::Node> Aspose::Words::Replacing::ReplacingArgs::get_MatchNode() const

Examples

Shows how to insert an entire document’s contents as a replacement of a match in a find-and-replace operation.

void InsertDocumentAtReplace()
{
    auto mainDoc = MakeObject<Document>(MyDir + u"Document insertion destination.docx");

    // We can use a "FindReplaceOptions" object to modify the find-and-replace process.
    auto options = MakeObject<FindReplaceOptions>();
    options->set_ReplacingCallback(MakeObject<ExRange::InsertDocumentAtReplaceHandler>());

    mainDoc->get_Range()->Replace(MakeObject<System::Text::RegularExpressions::Regex>(u"\\[MY_DOCUMENT\\]"), u"", options);
    mainDoc->Save(ArtifactsDir + u"InsertDocument.InsertDocumentAtReplace.docx");

}

        InsertDocument(para, subDoc);

        // Remove the paragraph with the matched text.
