如何在边缘标签中转义`>`？

Question

在我的点文件中

public class MyListAdapter extends BaseAdapter implements Filterable {

    private List<Product> myList;
    private List<Product> myListFull;
    private LayoutInflater mInflater;

    public MyListAdapter(List<Product> data, Context context) {
        myList = data;
        myList = new ArrayList(myList);
        myListFull = new ArrayList(myList);
        mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return myList.size();
    }

    @Override
    public Object getItem(int position) {
        return myList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        MyListAdapter.ViewHolder holder;

        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.listitem, parent, false);
            holder = new MyListAdapter.ViewHolder();

            holder.title = convertView.findViewById(R.id.listitem_title);
            holder.description = convertView.findViewById(R.id.listitem_subtitle);

            convertView.setTag(holder);
        } else {
            holder = (MyListAdapter.ViewHolder) convertView.getTag();
        }


        Product mProduct = (Product)getItem(position);
        holder.title.setText(mProduct.getProductName());
        holder.description.setText(mProduct.getProductDescription());

        return convertView;
    }


    /**
     * View holder
     */
    static class ViewHolder {
        private TextView title;
        private TextView description;
    }

    @Override
    public Filter getFilter() {
        return exampleFilter;
    }

    private Filter exampleFilter = new Filter() {
        @Override
        protected FilterResults performFiltering(CharSequence constraint) {
            List<Product> filteredList = new ArrayList<>();

            if (constraint == null || constraint.length() == 0) {
                filteredList.addAll(myListFull);
            } else {
                String filterPattern = constraint.toString().toLowerCase().trim();

                for (Product item : myListFull) {
                    if (item.getProductName().toLowerCase().contains(filterPattern)) {
                        filteredList.add(item);
                    }
                }
            }

            FilterResults results = new FilterResults();
            results.values = filteredList;

            return results;
        }

        @Override
        protected void publishResults(CharSequence constraint, FilterResults results) {
            myList.clear();
            myList.addAll((List<Product>) results.values);
            notifyDataSetChanged();
        }
    };
}

stdin_in -> file_out [label=<<font color="blue">tee >/dev/null</font>>]; 应该是标签的文本，但是它包含tee >/dev/null，这是一个特殊字符，因此>对此有所抱怨。我该怎么办？谢谢。

Answer 1

将文本放在引号中；将行更改为

stdin_in -> file_out[ label = "tee > /dev/null" fontcolor = "blue" ];

产生期望的结果：
