Detailed Description

Xml base class.

TiXmlBase is a base class for every class in TinyXml. It does little except to establish that TinyXml classes can be printed and provide some utility functions.

In XML, the document and elements can contain other elements and other types of nodes.

*   A Document can contain:
*     Element (container or leaf) 
*     Comment (leaf) 
*     Unknown (leaf) 
*     Declaration( leaf ) 
* 
*   An Element can contain: 
*     Element (container or leaf) 
*      Text (leaf) 
*      Attributes (not on tree)
*      Comment (leaf)
*      Unknown (leaf) 
* 
*   A Decleration contains: 
*      Attributes (not on tree) 
*

static void ConvertUTF32ToUTF8 ( unsigned long  input,
char *  output,
int *  length

Convert from UTF-32 to UTF-8

static const char* GetChar ( const char *  p,
char *  _value,
int *  length,
TiXmlEncoding  encoding 
)
inlinestaticprotected

Get a character, while interpreting entities. The length can be from 0 to 4 bytes.

References GetEntity().

static const char* GetEntity ( const char *  in,
char *  value,
int *  length,
TiXmlEncoding  encoding 
)
staticprotected

If an entity has been found, transform it into a character

void* GetUserData ( )
inline

Get a pointer to arbitrary user data.

References userData.

const void* GetUserData ( ) const
inline

Get a pointer to arbitrary user data.

static int IsAlpha ( unsigned char  anyByte,
TiXmlEncoding  encoding 
)
staticprotected

None of these methods are reliable for any language except English. Good for approximation, not great for accuracy.

static int IsAlphaNum ( unsigned char  anyByte,
TiXmlEncoding  encoding 
)
staticprotected

See IsAlpha()

static bool IsWhiteSpaceCondensed ( )
inlinestatic

Return the current white space setting

virtual void Print ( FILE *  cfile,
int  depth 
) const
pure virtual

All TinyXml classes can print themselves to a filestream or the string class (TiXmlString in non-STL mode, std::string in STL mode.) Either or both cfile and str can be null.

This is a formatted print, and will insert t abs and newlines.

(For an unformatted stream, use the << operator.)

Implemented in TiXmlDocument, TiXmlUnknown, TiXmlDeclaration, TiXmlText, TiXmlComment, TiXmlElement, and TiXmlAttribute.

Referenced by TiXmlAttribute::Print(), and TiXmlDeclaration::Print().

static void PutString ( const edelib::String str,
edelib::String out 
)
staticprotected

Puts a string to a stream, expanding entities as it goes. Note this should not contian the '<', '>', etc, or they will be transformed into entities!

static const char* ReadName ( const char *  p,
edelib::String name,
TiXmlEncoding  encoding 
)
staticprotected

Reads an XML name into the string provided. Returns a pointer just past the last character of the name, or 0 if the function has an error.

static const char* ReadText ( const char *  in,
edelib::String text,
bool  ignoreWhiteSpace,
const char *  endTag,
bool  ignoreCase,
TiXmlEncoding  encoding 
)
staticprotected

Reads text. Returns a pointer past the given end tag. Wickedly complex options, but it keeps the (sensitive) code in one place.

int Row ( ) const
inline

Return the position, in the original source file, of this node or attribute. The row and column are 1-based. (That is the first row and first column is 1,1). If the returns values are 0 or less, then the parser does not have a row and column value.

Generally, the row and column value will be set when the TiXmlDocument::Load(), TiXmlDocument::LoadFile(), or any TiXmlNode::Parse() is called. It will NOT be set when the DOM was created from operator>>. The values reflect the initial load. Once the DOM is modified programmatically (by adding or changing nodes and attributes) the new values will NOT update to reflect changes in the document.

There is a minor performance cost to computing the row and column. Computation can be disabled if TiXmlDocument::SetTabSize() is called with 0 as the value.

static void SetCondenseWhiteSpace ( bool  condense)
inlinestatic

The world does not agree on whether white space should be kept or not. In order to make everyone happy, these global, static functions are provided to set whether or not TinyXml will condense all white space into a single space or not. The default is to condense. Note changing this value is not thread safe.

void SetUserData ( void *  user)
inline

Set a pointer to arbitrary user data.

References userData.

static bool StringEqual ( const char *  p,
const char *  endTag,
bool  ignoreCase,
TiXmlEncoding  encoding 
)
staticprotected

Return true if the next characters in the stream are any of the endTag sequences. Ignore case only works for english, and should only be relied on when comparing to English words: StringEqual( p, "version", true ) is fine.

static int ToLower ( int  v,
TiXmlEncoding  encoding 
)
