Retrieving the Inner XML for a node

[Brian Rice]

Is there any way to retrieve the "inner" xml for a node? Essentially
node.stringValue, but without stripping out the tags.

For example:
<rss>
<channel>
<pubDate>Fri, 15 Jan 2010 16:31:02 PST</pubDate>
<textInput>
<title>Search News@Cisco</title>
<description></description>
<name>searchPhrase</name>
<link>http://www.cisco.com/pcgi-bin/search/search.pl</link>
</textInput>
</channel>
</rss>

So, for the pubDate node it would return: "Fri, 15 Jan 2010 16:31:02
PST"
But, for the textInput node it would return: "<title>News@Cisco</
title><description></description> ... </link>"

Thanks!

I believe you may be looking for the stringValue method. Let me know
if this is incorrect.

My testing seemed to indicate that xml tags are stripped out by
stringValue.

So, if you take my example, textInput node would return:
"News@CiscosearchPhrasehttp:// ..." rather than "<title>News@Cisco</

title><description></description> ... </link>"

Oops, you're right.  You could invoke the XMLString method on each of the children, and concatenate the results.  Something like this (a category method on DDXMLNode):

- (NSString *)innerXMLString

{

NSMutableString *mStr = [[NSMutableString alloc] init];

NSEnumerator *enumerator = [[self children] objectEnumerator];

NSXMLNode *child;

while(child = [enumerator nextObject])

{

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

NSString *str = [child XMLString];

if(str)

{

// From the documentation:

// The string to append must not be nil.

[mStr appendString:str];

}

[pool release];

}

return [mStr autorelease];

}

It's really too bad there is no function for this... it seems like I
would have to extract stuff from a lot of different areas. For
example... the node name, node attributes, comments, text nodes,
cdata... all kinds of things... that unfortunately I am sure I am
either unaware of or likely to forget something when I'm trying to
exactly recreate the inner xml of a node.

Any help would be appreciated! :)

Thanks.

The code that I posted passes your original 2 tests. I think it's
exactly what you want. I tested it before I posted it.
