Question

我正在解析XML文件users.xml，我希望将保存密码值的$3传递给trial.sh。 XML文件如下所示：

<Users>
<user>
<name>Veera</name>
<password>!#!veera@nbs</password>
</user>
</Users>

  awk '
    BEGIN { FS = "[<|>]" }
    {
           if ($2 == "password") 
           {
               if($3=="!#!veera@nbs")
                {
                   encrypted="'"`sh test.sh $3`"'" 
                   sub($3,encrypted)
                }
           }
            print
    }
    ' users.xml > users2.xml

XML文件包含元素password，$3包含我要传递给加密trial.sh（$3）的!#!veera@nbs的新密码，返回结果，该结果将存储在加密的awk变量中，并替换现有值。

        Intent intent = getActivity().getIntent();

    // insert data into database

    public void insertData(){

           //Insert our ContentValues

    private void deleteFromDB() {

        getActivity().getContentResolver().delete(SongContract.SongEntry.CONTENT_URI,

    private void checkFavourites() {

                        null,
                        SongContract.SongEntry.COLUMN_ID + " = ?",
                        new String[]{song.getsong_id()},
                        null);

        if (c != null) {
            c.moveToFirst();
            int index = c.getColumnIndex(SongContract.SongEntry.COLUMN_ID);

            if (c.getCount() > 0 && c.getString(index).equals(song.getsong_id())) {
                mIsFavourite = true;
                imgViewFavButton.setImageResource(android.R.drawable.btn_star_big_on);

            else{

            c.close();

        }



    }


    @Override
    public Loader<Cursor> onCreateLoader(int id, Bundle args){
        return new CursorLoader(getActivity(),
                SongContract.songEntry.CONTENT_URI,
                null,
                null,
                null,
                null);
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState){
        super.onViewCreated(view, savedInstanceState);
    }


    // Set the cursor in our CursorAdapter once the Cursor is loaded
    @Override
    public void onLoadFinished(Loader<Cursor> loader, Cursor data) {




    }

    // reset CursorAdapter on Loader Reset
    @Override
    public void onLoaderReset(Loader<Cursor> loader){

    }

}

这样：

$ awk -F'</?password>' 'NF>1{print $2}' file
!#!veera@nbs

以上假设您的文件总是与您的示例所显示的一样，并且没有（例如）与标记不同的行上的密码值。

我想在pass_flag的echo命令中传递test_var
