Several questions about Xerces-3.0
Hi,
I'm using Xerces-c-3.0 in my project under Linux. I have several questions.
1. What are pros and cons of using ICU library as a Transcoder?
2. I want to create a static version of my application.
I compiled Xerces with parameters *--enable-static --disable-shared*.
But when I try to compile my application I get following linker's errors:

You generally shouldn't convert the XML document data to UTF-16.
Instead, let the parser determine the encoding from the data itself.
For output, you should probably convert all UTF-16 strings to UTF-8, to
preserve data fidelity. This is usually not a problem, because UTF-8 is
compatible with US-ASCII.
You might have some issues displaying some strings to the console if
those strings have characters that aren't supported by the current code
page, but it's the best compromise to maintain data fidelity.
To transcode from UTF-16 to and from UTF-8, you need a UTF-8 transcoder.
You should search the archives of the user and developer list, as you
will find other emails that discuss this topic, along with code snippets.
Dave
RE: XMLString Class and ordinary C-strings
Posted by John Lilley <jl...@datalever.com>.
If they are really ASCII, you can just convert each character to n XMLCh and append them to the string one at the time.
You can also use Xerces' transcoder to transcode from the native locale's 8-bit code page, which unless it is something like EBCDIC will have ASCII as its lower 127 characters.

Using the DOMCount sample as a guide, I am developing a module with a

all output to cerr is to be converted to go to status strings in the

Re: Extracting data from nodes deep down in the hierarchy
Posted by Brian and Victoria <bn...@nc.rr.com>.
You could walk the document nodes using a xerces::DOMTreeWalker and its
functions...
::nextSibling()
::firstChild()
::nextChild()
::parentNode()
Each of these returns a xerces::DOMNode pointer and you can use its
functions (e.g., ::getNodeValue()) to extract the node data.
Since your document conforms to a schema, you know how the nodes are
ordered and nested.

Extracting data from nodes deep down in the hierarchy
Posted by "Rackl, Robert G" <ro...@boeing.com>.
Attached is a sample XML file from which I need to extract data. I am
using the DOM document approach, learning from the DOMCount sample code.
I am able to extract the data from the "Identification", "Grid",
"Solution", and "Results" nodes. I am also able to list the Names of the
three nodes called "Panel" using the getElementsByTagName method from
the document root. Where I am running into trouble is extracting the
attribute data for each element called "Node" [sorry about the use of
"Node" here for the corners of an aircraft fuselage panel] for a
particular Panel. What should be the approach here, please? (I tried
using getElementsByTagName from a "Panel" node - did not work; I tried
descending down the subtree using child nodes - could not make it work;
I thought about using filters - did not know where/how to start). Can
you point me to sample code for the approach you would recommend,
please?

Using XMLString::transcode() is dangerous when you don't know if the
strings you're transcoding are compatible with the local code page. The
safest approach is to use UTF-8, since it can represent all Unicode
characters.

Re: XMLString Class and ordinary C-strings

See XMLString::transcode(). Works boths ways. Just remember to use XMLString::release() as well.
char* myCString = "some string";
XMLCh* myXMLString = XMLString::transcode(myCString);
// use it
...
if (myXMLString != NULL) XMLString::release(&myXMLString);
or
...
const XMLCh* myXMLString = someNode->getTagName();
char* myCString = XMLString::transcode(myXMLString);
// use it
...
if (myCString != NULL) XMLString::release(&myCString);

RE: Using Schema in DOMCount
Posted by "Rackl, Robert G" <ro...@boeing.com>.
Thank you, Alberto.
Modified the command like so:
./DOMCount.g++ -v=always -n -s -f ~/practice/SamplePanelDat.xml
Modified the first few lines of the input file as follows:
<?xml version="1.0" encoding="UTF-8"?>
<PanelData xmlns="http://www.w3schools.com"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:namespaceSchemaLocation="http://www.w3schools.com
~/practice/ADINB_PanelData.xsd">
<Identification ID="12345" Case="Sample for demonstrating XML
format, successful aero data extraction, fictitious data"/>
Schema file not changed.
I am still getting the same errors. Do you see anything else wrong?

Two things are wrong here:
1) you need the -n option to enable namespaces
2) the schema is for the namespace http://www.w3schools.com, the XML
document uses that namespace, but you bind them by using the
xsi:noNamespaceSchemaLocation (that should be used for documents that
don't use namespaces). You should use an attribute
xsi:namespaceSchemaLocation="http://www.w3schools.com
~/practice/ADINB_PanelData.xsd"

Using Schema in DOMCount
Posted by "Rackl, Robert G" <ro...@boeing.com>.
After having used xml on Windows, I am now trying to use xml in Linux
using xerces. I am new to xerces and fairly new to C++. Successfully
compiled the DOMCount sample program. But I am unsuccessful in trying to
have DOMCount validate the input xml file using the command
./DOMCount -v=always -s -f ~/practice/SamplePanelDat.xml
(tried various combinations of -n, -s, -f options - to no avail)
Many errors are reported as if the schema file did not exist (but it
does). The first few lines of the input file are thus:
<?xml version="1.0" encoding="UTF-8"?>
<PanelData xmlns="http://www.w3schools.com"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="~/practice/ADINB_PanelData.xsd">
<Identification ID="12345" Case="Sample for demonstrating XML
format, successful aero data extraction, fictitious data"/>
The first few lines of the schema file ADINB_PanelData.xsd are thus:
<?xml version="1.0" encoding="UTF-8"?>

Re: Several questions about Xerces-3.0
Posted by Alberto Massari <am...@datadirect.com>.
Same as for ICU: plain socket requires no external libraries, but it
supports a very limited set of HTTP (no proxy resolving, no
authentication, no compression, etc... it barely supports redirection);
libcurl requires cUrl to be availbale, but it handles the full HTTP specs.

I figured out what the problem was. Yes, I added -lxerces-c option but it
was added at the beginning of the libraries list. I add it to the end of the
list and application links with no errors.
Can you also clarify the difference between plain sockets and libcurl?

How to createElement from CString variable
Posted by Rupanu Ranjaneswar <ru...@yahoo.com>.
I have a CString variable and when I invoke createElement it crashes.(I am using VC++ 6.0)Code snippet given below..
XMLCh* elementTag = strMyCString.AllocSysString();pElement = pDOMDocument->createElement(elementTag);
Re: Several questions about Xerces-3.0
Posted by Alberto Massari <am...@datadirect.com>.
ICU gives you the capability of processing a lot more encodings than the
plain Xerces, but it requires you to bundle an external library that is
pretty big.
Did you add the -L<xerces path> -lxerces-c options to the link command
line ?
