int RTT::marsh::TiXmlDocument::ErrorRow | ( | ) | [inline] |
Returns the location (if known) of the error.
The first column is column 1, and the first row is row 1. A value of 0 means the row and column wasn't applicable (memory errors, for example, have no row/column) or the parser lost the error. (An error in the error reporting, in that case.)

const TiXmlNode * RTT::marsh::TiXmlNode::IterateChildren | ( | const TiXmlNode * | previous | ) | const [inherited] |
An alternate way to walk the children of a node.
One way to iterate over nodes is:
for( child = parent->FirstChild(); child; child = child->NextSibling() )
IterateChildren does the same thing with the syntax:
child = 0; while( child = parent->IterateChildren( child ) )
IterateChildren takes the previous child as input and finds the next one. If the previous child is null, it returns the first. IterateChildren will return null when done.

TiXmlNode * RTT::marsh::TiXmlNode::LinkEndChild | ( | TiXmlNode * | addThis | ) | [inherited] |
Add a new node related to this.
Adds a child past the LastChild.
NOTE: the node to be added is passed by pointer, and will be henceforth owned (and deleted) by tinyXml. This method is efficient and avoids an extra copy, but should be used with care as it uses a different memory model than the other insert functions.

bool RTT::marsh::TiXmlDocument::LoadFile | ( | FILE * | file, |

const TiXmlElement* RTT::marsh::TiXmlDocument::RootElement | ( | ) | const [inline] |

References RTT::marsh::TiXmlNode::FirstChildElement().
int RTT::marsh::TiXmlBase::Row | ( | ) | const [inline, inherited] |
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 RTT::marsh::TiXmlBase::SetCondenseWhiteSpace | ( | bool | condense | ) | [inline, static, inherited] |
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 values is not thread safe.
void RTT::marsh::TiXmlDocument::SetTabSize | ( | int | _tabsize | ) | [inline] |
SetTabSize() allows the error reporting functions (ErrorRow() and ErrorCol()) to report the correct values for row and column.
It does not change the output or input in any way.
By calling this method, with a tab size greater than 0, the row and column of each node and attribute is stored when the file is loaded. Very useful for tracking the DOM back in to the source file.
The tab size is required for calculating the location of nodes. If not set, the default of 4 is used. The tabsize is set per document. Setting the tabsize to 0 disables row/column tracking.
Note that row and column tracking is not supported when using operator>>.
The tab size needs to be enabled before the parse or load. Correct usage:
TiXmlDocument doc; doc.SetTabSize( 8 ); doc.Load( "myfile.xml" );
void RTT::marsh::TiXmlNode::SetValue | ( | const char * | _value | ) | [inline, inherited] |
