Detailed Description

A little DOM-style library to handle parsing and processing an XML file.

It only handles elements, attributes and pcdata content. <! ... > and <? ... > are silently ignored. pcdata is collected into one string, sans leading whitespace first line.

The following is an example of a cannonical usage for the lilxml library. Initialize a lil xml context and read an XML file in a root element.

    #include <lilxml.h>
    
    LilXML *lp = newLilXML();
    char errmsg[1024];
    XMLEle *root, *ep;
    int c;

    while ((c = fgetc(stdin)) != EOF) {
        root = readXMLEle (lp, c, errmsg);
        if (root)
        break;
        if (errmsg[0])
        error ("Error: %s\n", errmsg);
    }
 
        // print the tag and pcdata content of each child element within the root 

        for (ep = nextXMLEle (root, 1); ep != NULL; ep = nextXMLEle (root, 0))
        printf ("%s: %s\n", tagXMLEle(ep), pcdataXMLEle(ep));


    // finished with root element and with lil xml context

    delXMLEle (root);
    delLilXML (lp);
