[gdal-dev] RE: CPLXMLNode, no GetChilds()'like method ?

[Aurélien Kamel]

Actually I have one more question for you. Imagine you have an xml file like
this :

---- start of xml file ----
<?xml version="1.0"?>

<a b="xxx">
  <b>
    ...
  </b>
</a>
---- end of xml file ----

How can you access to the node "a" if you don't know its name ? I tried to
do a recursive function that would loop on all the nodes of the file
starting from ROOT.

With the following code I'll only recurse on the "<?xml version="1.0"?>"
node.

bool
MyDriver::parse(const char *filename) {
  CPLXMLNode* xmlNode = CPLParseXMLFile(filename);
  If (!xmlNode) return false;
  return parseLoop(xmlNode);
}

bool
MyDriver::parseLoop(CPLXMLNode *node) {
  std::cout << "Currently recursing on node: " << node->pszValue <<
std::endl;
  
  for (CPLXMLNode *brother = node->psChild;
       brother;
       brother = brother->psNext)
    if (!parseLoop(brother)) return false;

  return true;
}

Any idea how I'll could recurse on all the nodes that are child of ROOT ?

Thanks,
aurel

I found my answer. I can use the public attribute psNext that point to the
next sibling.

Sorry.

Hello,

I have to parse a XML file in a driver I'm writing for OGR and I would like
to do a recursive method that would take a xml node as argument and then
call itself on each of the child of this node.

Is there a way to get the child list of a node with CPLXMLNode ? For the
moment I can't figure how I could do this with cpl_minixml...

Thanks,
