Managing Headers

Headers are special tags in XML files which describe the document (such as <?xml?> or <!DOCTYPE>).

If the flag GWEN_XML_FLAGS_HANDLE_HEADERS is on upon reading of files these special toplevel tags are added to the current node's header list instead of the normal children node list.

If the same flag is given when writing files the header tags of the given root node are written to the output stream before its children.

Header nodes are identified as nodes whose name begins with '?' or '!'.

GWENHYWFAR_API void GWEN_XMLNode_ClearHeaders (GWEN_XMLNODE *root)

Managing Properties/Attributes

A property (in XML notation this is called attribute) is given within a tag (in XML notation this is called element), like in this example:

 <tag property="1" />

Usage Counter

The usage counter of a node is only used by applications, not by Gwenhywfar itself. So if the application does not set this counter it will always be zero.

An application could use this counter to check whether a given node is still in use by some parts of the application in order to free unused nodes.

Handling Tags As Variables

These functions look for a tag, read their first data element and return it as if it was a DB variable. This simplifies access to simple tags containing simple data tags only. E.g. if your XML structure is this:

 <test>
   <X> 15 </X>
   <Y> 10 </Y>
 </test>

... then you can access the value of X with the following call:

 x=GWEN_XMLNode_GetIntValue(testNode, "X", 0);

If the given variables do not exist or have no value then the also given default value will be returned.

If this flag is given this module will be more tolerant when encountering and end element (e.g. </html>). If the name of the end element does not match the currently open element then the element to be closed is searched above the currently open element. This works around problems with malformed XML files.

Adds a node as a child to another one. This function does not make deep copies. Instead it takes over ownership of the new child.

Parameters:
nnode to which the new node is to be added (i.e. the node which becomes the parent of the second argument)
childchild which is to be added (this function takes over ownership of that node, so you MUST NOT free the node yourself)

Searches for the first matching tag/element below the given one. Lets say you have the following XML file:

  <DEVICES>
    <DEVICE id="dev1" />
    <DEVICE id="dev2" />
  </DEVICES>

If you are looking for a device called "dev2" then you should call this function like this:

   tag=GWEN_XMLNode_FindFirstTag(root, "DEVICE", "id", "dev2");
Returns:
pointer to the tag/element if found, 0 otherwise
Parameters:
ntag/element below which to search
tnametag/element name (e.g. if the tag is "<TESTTAG>" then the tag name is "TESTTAG"). Wildcards (like "*") are allowed.
pnamename of the property/attribute to check (if 0 then no property/attribute comparison takes place). No wildcards allowed.
pvalueoptional value of the property/attribute to compare against, wildcards allowed.

This function does the same as GWEN_XMLNode_GetCharValue, but it looks for an element with the attribute "lang" which matches the currently selected locale (e.g. "lang=de" for Germany). If there is no localized version of the given element then the first element of that name is used (withouth "lang" attribute). Therefore XML documents used with this function should contain unlocalized elements along with localized ones to provide a fallback.

GWENHYWFAR_API int GWEN_XMLNode_IsChildOf ( const GWEN_XMLNODE parent,
const GWEN_XMLNODE child 
)

Checks whether the second node is a child of the first one.

Returns:
0 if statement is not true, !=0 otherwise

INTERNAL. Iterates on the same level in the XML tree from the given node to the next one on the same level (i.e. the returned node has the same parent node as the given element). The returned node may be a tag/element node, or a property/attribute node, or a data node. You will probably prefer to use GWEN_XMLNode_GetNextTag() instead of this function.

Returns:
The next node on the same level, or NULL if no more element exists.

Unlinks the given child node from its parent without freeing it. This function relinquishes the ownership of the child to the caller who thereby becomes responsible for freeing this node.

Parameters:
nnode which is suspected to be the parent of the second argument
childnode which is to be unlinked
