Detailed Description

The csvdom class implements a minimal CSV DOM parser.

It parses a file or string of CSV-formatted data and produces a dom tree representing the data. It creates an "h" element for the header, "c" element for each column, "r" element for each row, and "f" element for each field. To each "c" and "f" element, it adds a "v" attribute, containing the value, and a "q" element which can contain "y" or "n" indicating whether or not the value is quoted.

For example, the following CSV:

"col1","col2",col3,col4 field11,field12,"field13","field14" "field21",field22,field23,"field24" field31,"field32",field33,field34

would produce the following dom tree:

<h> </h> <r> <f v="field11" q="n"> <f v="field12" q="n"> <f v="field13" q="y"> <f v="field14" q="y"> </r> <r> <f v="field21" q="y"> <f v="field22" q="n"> <f v="field23" q="n"> <f v="field24" q="y"> </r> <r> <f v="field31" q="n"> <f v="field32" q="y"> <f v="field33" q="n"> <f v="field34" q="n"> </r>

Constructor & Destructor Documentation

◆ csvdom() [1/2]

csvdom::csvdom ( )

Creates a new instance of the csvdom class.

◆ csvdom() [2/2]

csvdom::csvdom ( bool stringcacheenabled )

Creates a new instance of the csvdom class, allowing the user to enable or disable the "string cache" for this instance.

By default, as each csvdomnode is added to the csvdom tree, tag and attribute names and values are stored in a string cache and pointers into the cache are assigned to each node. Reference counters are kept and the string is removed from the cache when no more nodes are using it. If the data is highly repetitive this conserves memory at the cost of speed.

If the string cache is disabled then memory is allocated in each csvdomnode for names and values and freed when the csvdomnode is freed. This is faster but uses much more memory.

◆ ~csvdom()

virtual csvdom::~csvdom ( )

virtual

Deletes this instance of the csvdom class.
