如何解析带有特殊字符的xml?专门用于&符号 [英] how to parse xml with special character? specifically for ampersand

问题描述

我从文本框中获取数据并将其更改为 xml 格式并将其存储在数据库中.为了允许特殊字符，我编写了 javascript 函数来用它的 html 实体替换特殊字符.

I am getting data from text box and change it into xml format and store it in data base. For allowing special characters i wrote javascript function to replace special character with its html entities.

 "     "
 &     &
 <     &lt;
 >     &gt;

对于引号，小于，大于"它的工作正常.对于&"它显示 xml 解析器错误我用javascript用它的实体替换特殊字符

for "quotes , less than , greater than" its working fine. for "&" it is showing xml parser error i used javascript to replace special character with its entity

  string.replace(/</g, '&lt;').replace(/>/g, '&gt;').replace(/&/g, '&amp;').replace(/"/g, '&quot;').replace(/'/g, "\\'");

  for "&" allow showing warning but it get stored in data base. please help me to sort out this problem . 


 i begin with string.replace(/&/g, '&amp;') even though i am getting 

警告:SimpleXMLElement::__construct():实体:第 9 行:解析器错误:EntityRef:期望 ';'在/var/www/我也试过这个 &如此链接中所述stackoverflow.com/questions/1328538/...
之后没有警告，但在保存在数据库中时，它保存为ab &amp cd"

Warning: SimpleXMLElement::__construct(): Entity: line 9: parser error : EntityRef: expecting ';' in /var/www/ i tried this also & as mentioned in this link stackoverflow.com/questions/1328538/…
After that there is no warning but while saving in db it saved as "ab &amp cd"

推荐答案

Start 替换 & 字符，then 替换另一个人物.否则，您将用 &

Start with replacing the & character, then replace the other characters. Otherwise you will replace & from the previous entities (< etc.) by &

string.replace(/&/g, '&amp;amp;') //<= start with
      .replace(/</g, '&lt;')
      .replace(/>/g, '&gt;')
      .replace(/"/g, '&quot;')
      .replace(/'/g, '&apos');
// &apos; may be "\\'",  depends on how te OP wants to use it

[edit based on comments]使用&替换&符号

[edit based on comments] use & to replace the ampersand character
