ezXML - XML Parsing C Library

version 0.8.5

ezXML is a C library for parsing XML documents inspired by simpleXML for PHP.

As the name implies, it's easy to use. It's ideal for parsing XML configuration

files or REST web service responses. It's also fast and lightweight (less than

20k compiled). The latest verions is available here:

http://prdownloads.sf.net/ezxml/ezxml-0.8.6.tar.gz?download

Example Usage

Given the following example XML document:

  

    

      Kimi Raikkonen

      112

    

    

      Juan Pablo Montoya

      60

    

  

This code snippet prints out a list of drivers, which team they drive for,

and how many championship points they have:

ezxml_t f1 = ezxml_parse_file("formula1.xml"), team, driver;

const char *teamname;

for (team = ezxml_child(f1, "team"); team; team = team->next) {

    teamname = ezxml_attr(team, "name");

    for (driver = ezxml_child(team, "driver"); driver; driver = driver->next) {

        printf("%s, %s: %s\n", ezxml_child(driver, "name")->txt, teamname,

               ezxml_child(driver, "points")->txt);

    }

}

ezxml_free(f1);

Alternately, the following would print out the name of the second driver on the

first team:

ezxml_t f1 = ezxml_parse_file("formula1.xml");

printf("%s\n", ezxml_get(f1, "team", 0, "driver", 1, "name", -1)->txt);

ezxml_free(f1);

The -1 indicates the end of the argument list. That's pretty much all

there is to it. Complete API documentation can be found in ezxml.h.

Known Limitations

- ezXML is not a validating parser

- Loads the entire XML document into memory at once and does not allow for

  documents to be passed in a chunk at a time. Large XML files can still be

  handled though through ezxml_parse_file() and ezxml_parse_fd(), which use mmap

  to map the file to a virtual address space and rely on the virtual memory

  system to page in data as needed.

- Does not currently recognize all possible well-formedness errors. It should

  correctly handle all well-formed XML documents and will either ignore or halt

  XML processing on well-formedness errors. More well-formedness checking will

  be added in subsiquent releases.

- In making the character content of tags easy to access, there is no way

  provided to keep track of the location of sub tags relative to the character

  data. Example:

  line one


  line two

  The character content of the doc tag is reported as "line one\nline two", and

  
 is reported as a sub tag, but the location of 
 within the

  character data is not. The function ezxml_toxml() will convert an ezXML

  structure back to XML with sub tag locations intact.
