Reading contents of XML node
I'm writing some functions in C that parses a part of a XML file (using libxml), but instead of extracting the content of the XML node that has a specific name, it outputs a string that's not in UTF-8 or ASCII.
Here's the XML file in question:
<paths>
<file_list>
<group>
<type>config_directory</type>
<file>
<name>AppData/scripts/preferences.empire_script.txt</name>
<sum>5d064a6cfdc35f4714fd31d5d99735d0</sum>
</file>
<file>
<name>preferences</name>
<sum>a0f283d89d97a00011f292cc8f9c0d24</sum>
</file>
</group>
</file_list>
</paths>
This is the first function I call, which parses the XML file and finds the XML node with name "file_list"
int
verify()
{
xmlDoc *doc = NULL;
xmlNode *root_element, *cur_node;
doc = xmlReadFile("test.xml", NULL, 0);
if (doc == NULL)
{
return 1;
}
root_element = xmlDocGetRootElement (doc);
if (root_element->type != XML_ELEMENT_NODE || !xmlStrEqual(root_element->name, (const xmlChar*) "paths"))
{
return 1;
}
cur_node = root_element->children;
while (cur_node != NULL)
{
if (cur_node->type == XML_ELEMENT_NODE && xmlStrEqual(cur_node->name, (const xmlChar*) "file_list"))
{
if (parse_file_list(cur_node, e) != 0) return 1;
}
cur_node = cur_node->next;
}
file_close(f);
return 0;
}
Then I do the same thing in this function and find "group"
static int
parse_file_list(xmlNode *cur)
{
cur = cur->children;
while (cur != NULL)
{
if (cur->type == XML_ELEMENT_NODE && xmlStrEqual(cur->name, (const xmlChar*) "group"))
{
if (parse_group(cur) != 0) return 1;
}
cur = cur->next;
}
return 0;
}
Here, it should parse the contents of the XML node "type", except I just get a segmentation fault when I call xmlNodeGetContent(cur)
static int
parse_group(xmlNode *cur)
{
cur = cur->children;
while (cur != NULL)
{
if (cur->type == XML_ELEMENT_NODE && xmlStrEqual(cur->name, (const xmlChar*) "type"))
{
xmlChar *key = xmlNodeGetContent(cur);
xmlFree(key);
break;
}
cur = cur->next;
}
return 0;
}
Am I missing something?
