Java:将格式化的xml文件转换为一行字符串 [英] Java : Convert formatted xml file to one line string

问题描述

我有一个格式化的XML文件，我想将其转换为一个行字符串，我该怎么做.

示例xml:

<?xml version="1.0" encoding="UTF-8"?>
<books>
   <book>
       <title>Basic XML</title>
       <price>100</price>
       <qty>5</qty>
   </book>
   <book>
     <title>Basic Java</title>
     <price>200</price>
     <qty>15</qty>
   </book>
</books>

预期产量

<?xml version="1.0" encoding="UTF-8"?><books><book> <title>Basic XML</title><price>100</price><qty>5</qty></book><book><title>Basic Java</title><price>200</price><qty>15</qty></book></books>

谢谢.

解决方案

//filename is filepath string
BufferedReader br = new BufferedReader(new FileReader(new File(filename)));
String line;
StringBuilder sb = new StringBuilder();

while((line=br.readLine())!= null){
    sb.append(line.trim());
}

使用StringBuilder效率要比concat http://kaioa.com/node/59

I have a formatted XML file, and I want to convert it to one line string, how can I do that.

Sample xml:

<?xml version="1.0" encoding="UTF-8"?>
<books>
   <book>
       <title>Basic XML</title>
       <price>100</price>
       <qty>5</qty>
   </book>
   <book>
     <title>Basic Java</title>
     <price>200</price>
     <qty>15</qty>
   </book>
</books>

Expected output

<?xml version="1.0" encoding="UTF-8"?><books><book> <title>Basic XML</title><price>100</price><qty>5</qty></book><book><title>Basic Java</title><price>200</price><qty>15</qty></book></books>

Thanks in advance.

//filename is filepath string
BufferedReader br = new BufferedReader(new FileReader(new File(filename)));
String line;
StringBuilder sb = new StringBuilder();

while((line=br.readLine())!= null){
    sb.append(line.trim());
}

using StringBuilder is more efficient then concat http://kaioa.com/node/59
