Escaping an xml string in java

Question

I read elements with CDATA sections from a rss-feed which I need to convert to valid xml. The content in the CDATA section is mostly valid xhtml, but some times characters like ampersand appear in attributes (url's).

I can use .replaceAll("&", "&") to solve this but thinking a bit forward it may be that other invalid characters show up in attributes or text.

The CMS to which I'm importing the element, won't accept CDATA sections without setting up another configuration for the content, so my question is: is there any simple way to escape the string, only for attributes and text?

I'm using the jdom library to manipulate the xml after the import.

Edit: I've checked out apache's StringEscapeUtils, but this is escaping the whole string. I need something that will only escape attribute values and text inside elements.

Answer 1

Apache Commons 为此提供了方便的函数： StringEscapeUtils

When you use JDOM it will automatically correctly escape ay content that needs it. Is your CMS loaded with the output of JDOM, or are you using some other library to populate the CMS...?

In essence, if you have valid XML input, and you use JDOM (something from org.jdom2.output.*) to output the data, then you will always have good output.... so, what are you doing to have broken output?
