从服务器收到的XML响应中的特殊字符

Question

In my Scala code, I am fetching a response from a server using the getInputStream method of HttpUrlConnection class. The response is XML data. However the data contains HTML entities like & and ' .

Is there a way I can replace these characters with their text equivalent so that I can parse the XML properly?

Answer 1

It's necessary to encode those entities in xml so they don't interfere with its syntax. The < (<) and > (>) entities make this more obvious. It would be impossible to parse XML whose content was littered with < and > symbols.

Scala's scala.xml package should give you the tools you need to parse your xml. Here's some guidance from the library's author.
