How can i get the string in &lt;image&gt; tags with getValue?&lt;image&gt;https://i2.cnnturk.com/i/cnnturk/75/720x490/5e6f7a9a70380e0cc8f49313&lt;/image&gt;

i need https://i2.cnnturk.com/i/cnnturk/75/720x490/5e6f7a9a70380e0cc8f49313 as value.

I'm able to show image, if it's &lt;media:content url=&quot;&quot;/&gt; &lt;media:thumbnail url=&quot;&quot;/&gt; &lt;enclosure url=&quot;&quot;/&gt; and need to show &lt;image&gt; too.

Also is there any way to format RSS publish date GMT to GMT+3? I need to show as different timezone.

RSS Item:

  1. &lt;item&gt;

你可以尝试使用正则表达式 \&lt;(\Qimage\E)\&gt;(.*?)\&lt;\/\1\&gt; 来匹配相应的字符。它可以匹配所有图像标签的内容。

  1. public static void main(String[] args){
  2.     String s = "&lt;image&gt;https://x.com/image.jpg&lt;/image&gt;"
  3.                 + "&lt;image&gt;https://x.com/image1.jpg&lt;/image&gt;"
  4.                 + "&lt;image&gt;https://x.com/image2.jpg&lt;/image&gt;";
  5.     Pattern p = Pattern.compile("\\&lt;(\\Qimage\\E)\\&gt;(.*?)\\&lt;\\/\\1\\&gt;");
  6.     Matcher m = p.matcher(s);
  7.     while(m.find()){
  8.         System.out.println(m.group(2));
  9.     }
  10. }

如果你不想使用正则表达式：

  1. int record = 0;
  2. while(record != -1){
  3.     int a = qName.indexOf("&lt;image&gt;", record);
  4.     if(a == -1){
  5.         break;
  6.     }
  7.     int b = qName.indexOf("&lt;/image&gt;", a);
  8.     String url = qName.substring(a + 7, b + 8);
  9.     System.out.println(url);
  10. }
英文:

You can try the regular expression \&lt;(\Qimage\E)\&gt;(.*?)\&lt;\/\1\&gt;To match the corresponding characters.It can match contents of all image labels.

  1. public static void main(String[] args){
  2. String s=&quot;&lt;image&gt;https://x.com/image.jpg&lt;/image&gt;&quot;
  3. + &quot;&lt;image&gt;https://x.com/image1.jpg&lt;/image&gt;&quot;
  4. + &quot;&lt;image&gt;https://x.com/image2.jpg&lt;/image&gt;&quot;;
  5. Pattern p = Pattern.compile(&quot;\\&lt;(\\Qimage\\E)\\&gt;(.*?)\\&lt;\\/\\1\\&gt;&quot;);
  6. Matcher m = p.matcher(s);
  7. while(m.find()){
  8. System.out.println(m.group(2));
  9. }
  10. }

Update: I just updated the code. I'm sorry I wrote it wrong before.

if you don't want to use the regular expression

  1. int record = 0;
  2. while(record!=-1){
  3. int a = qName.indexOf(&quot;&lt;image&gt;&quot;,record);
  4. if(a==-1){
  5. break;
  6. }
  7. int b = qName.indexOf(&quot;&lt;/image&gt;&quot;,a);
  8. String url=qName.substring(a+7,b+8);
  9. System.out.println(url);

}

  1. String sete = "<image>https://x.com/a.jpg</image>";
  2. String sete2 = sete.replace("<image>", "");
英文: 
  1. String sete = &quot;&lt;image&gt;https://x.com/a.jpg&lt;/image&gt;&quot;;
  2. String sete2 = sete.replace(&quot;&lt;image&gt;&quot;, &quot;&quot;);
