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:

&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。

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

如果你不想使用正则表达式:

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

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

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

if you don't want to use the regular expression

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

}

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