In modern contexts, XML has emerged as a widely accepted standard for publishing multimedia and technical documents across various platforms. Numerous editing applications, management systems, and publishing tools, alongside multiple industry standards, depend significantly on XML. However, despite its broad usage, XML has encountered challenges in certain areas because of its clear distinction between document structure and presentation. Many editors favor word processors such as Microsoft Word, which allow text and formatting to be developed simultaneously, offering immediate visual feedback. In contrast, XML necessitates a more conceptual approach, where content is embedded with structural tags, and the visual layout is determined at later stages of production. Meanwhile, SimQin improves the user experience by allowing documents to be viewed in layout mode right from the start while simultaneously showcasing the underlying XML structure and organization. This ability to see both aspects concurrently can streamline the editing workflow and may enhance XML's attractiveness to those familiar with conventional word processing applications. Ultimately, the combination of layout visibility and structural clarity offered by SimQin could encourage more users to embrace XML for their publishing needs.
