Storing base64 data in XML?

阅读更多关于 Storing base64 data in XML?

问题 How I can store base64 strings in XML? Do you use CDATA to store base64 strings in XML? Would it help as it allows use of < > within the strings? Is base64 configurable where you tell it not to use certain chars if they conflict with XML? 回答1: You can just store it as a text or attribute value; no escaping or CDATA sections needed. The standard base 64 characters + and / (other than a-z , A-Z and 0-9 ) do not interfere with XML parsing at all. 回答2: Base64 only uses alphanumeric characters and

I have this difficult situation where I need to use the CDATA tags inside another CDATA tags. The situation is simple to explain though. I have the following thing: <edit> <![CDATA[ <script type="text/javascript"> <![CDATA[ window.onload = function() { document.getElementById('block').onclick = function() { this.onclick = ''; this.value = '{LA_SEND_CONFIRM}'; this.className = this.className.replace('button1',''); document.getElementById('replacement').value = '{LA_BLOCK_CODE}'; } } ]]> </script> ]]> </edit> I need to wrap my Javascript inside CDATA too for showing purposes, so when I open that

How can i grab CData out of BeautifulSoup

阅读更多关于 How can i grab CData out of BeautifulSoup

I have a website that I'm scraping that has a similar structure the following. I'd like to be able to grab the info out of the CData block. I'm using BeautifulSoup to pull other info off the page, so if the solution can work with that, it would help keep my learning curve down as I'm a python novice. Specifically, I want to get at the two different types of data hidden in the CData statement. the first which is just text I'm pretty sure I can throw a regex at it and get what I need. For the second type, if i could drop the data that has html elements into it's own beautifulsoup, I can parse

Using NSXMLParser with CDATA

I'm parsing an RSS feed with NSXMLParser and it's working fine for the title and other strings but one of the elements is an image thats like <!CDATA <a href="http:image..etc> How do I add that as my cell image in my table view? Would I define that as an image type?

Decode CDATA section in C#

问题 I have a bit of XML as follows: <section> <description> <![CDATA[ This is a "description" that I have formatted ]]> </description> </section> I'm accessing it using curXmlNode.SelectSingleNode("description").InnerText but the value returns \r\n This is a "description"\r\n that I have formatted instead of This is a "description" that I have formatted. Is there a simple way to get that sort of output from a CDATA section? Leaving the actual CDATA tag out seems to have it return the same way.

Use CDATA to store raw binary streams?

阅读更多关于 Use CDATA to store raw binary streams?

Instead of the overhead with saving binary as Base64 , I was wondering if you could directly store double-byte binary streams into XML files, using CDATA, or commenting it out, or something? You can store it as CDATA, but there's the risk that some byte sequences will evaluate to valid XML that closes the CDATA section. After a quick look at http://www.w3.org/TR/2006/REC-xml-20060816/#sec-cdata-sect , it seems you can have any sequence of chars except "]]>". Have a look at what is a valid XML char too. The Nul character ( '\0' in C ) is not valid anywhere in XML, even as an escape ( & #0; ).

I need to serialize my object in such a way that the properties I want, would get wrapped around CData sections.
