I'm trying to create a simple XML document which holds information
regarding text styling, so it is important to maintain white space
between words, but I'm having difficulty achieving this. Here's an
example.
I'd like to form this string into an XML element:
NSString *xmlString =@"<paragraph>The <bold>cat</bold>
<italic>sat</italic> on the <bold>mat</bold></paragraph>";
if I try this:
NSXMLElement *xml = [[[NSXMLElement alloc]
initWithXMLString:xmlString error:&err]autorelease];
then I lose the spacing between 'cat' and 'sat'.
I can use:
NSXMLDocument *xml = [[[NSXMLDocument alloc]
initWithXMLString:xmlString options:NSXMLNodePreserveWhitespace
error:&err]autorelease];
which preserves spacing, though I don't want a new NSXMLDocument,
I need a new element to add to an existing document.
Is there a way of creating an NSXMLElement with
'options:NSXMLNodePreserveWhitespace'?
I've attempted using:
NSXMLElement *xml = [[[NSXMLElement alloc]
initWithKind:NSXMLElementKind options:NSXMLNodePreserveAll]
autorelease];
and then setting the name and string. However, the XML in the
string is then escaped as thus: <bold>cat</bold>
Your problem has nothing to do with Cocoa…
XML-in-XML is a classic question in XML forums…
- escaping <, > as entities,
- using CDATA, e.g. @"<![CDATA[<paragraph>The <bold>cat</bold>
<italic>sat</italic> on the <bold>mat</bold></paragraph>]]>"
- encoding the XML-in-XML in base64
- using a related DTD with CDATA section definitions
- …
are among the classic solutions…
True, but maybe there is a simple Cocoa solution:
NSXMLDocument *fragment = [[[NSXMLDocument alloc]
initWithXMLString:xmlString
options:NSXMLNodePreserveWhitespace error:&err] autorelease];
Then add [fragment rootElement] to your document.
