import com.groupdocs.watermark.contents.WordProcessingShape;

// Iterate through all shapes in the first section of the document
for (WordProcessingShape shape : content.getSections().get_Item(0).getShapes()) {
    // Check if the shape contains the target text
    if (shape.getText().contains("Some text")) {
        // Replace the text with new text
        shape.setText("Another text");
    }
}
