Question

我有以下文字：

xml = '''
<accessibility_info>
    <accessibility role="captions" available="true" />
</accessibility_info>
<crew_member billing="top"
    <display_name>John Viscount</display_name>
</crew_member>
<products>
    <territory>GB</territory>
</products>'''

我需要删除以下<crew_member>块。这就是我目前正在做的事情：

clean_xml = re.sub('<crew_member>.*</crew_member>', '', metadata_contents, 
                    flags=re.DOTALL)

但是，它还添加了换行符：

<accessibility_info>
    <accessibility role="captions" available="true" />
</accessibility_info>

<products>
    <territory>GB</territory>
</products>

我如何更改正则表达式以剥离换行符，所以它看起来像：

<accessibility_info>
    <accessibility role="captions" available="true" />
</accessibility_info>
<products>
    <territory>GB</territory>
</products>'

Answer 1

试试这个

print re.sub('<crew_member([^\>]*)>.*</crew_member>\n', '', xml, flags=re.DOTALL)

Answer 2

我知道这有点旧，但我想说新行实际上来自用于将新文本写入文件的方法。如果我使用public class DetailedActivity extends AppCompatActivity { //declared variables TextView txtName, txtEmail, txtPhone; Bundle img; String name; String email; String phone; ImageView imageView; Context mContext; Bitmap bitmap; @RequiresApi(api = Build.VERSION_CODES.M) @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_detailed); //Get Intent Intent i = getIntent(); //items to receive intent name = i.getStringExtra("name"); email = i.getStringExtra("email"); phone = i.getStringExtra("phone"); bitmap = i.getParcelableExtra("imageView"); //Assign values to layout file items txtName = (TextView) findViewById(R.id.tvName); txtEmail = (TextView) findViewById(R.id.tvEmail); txtPhone = (TextView) findViewById(R.id.txtPhone); imageView = (ImageView) findViewById(R.id.profilPic); /** * Set parsed Text */ txtName.setText(name); txtEmail.setText(email); txtPhone.setText(phone); imageView.setImageBitmap(bitmap);，则会添加新行，但如果我使用print()，则不会添加新行。

re.sub在python中添加换行符
