Bug 26302 – GDOM-Binding: errors when executing XPath

• Component: WebKit API
• Status: RESOLVED INVALID

[Leon Winter]

Hi,

during execution of XPath via GDOM Binding there is intersting output:

 (test:32645): GLib-GObject-CRITICAL **: g_param_spec_double: assertion
  `default_value >= minimum && default_value <= maximum' failed

  (test:32645): GLib-GObject-CRITICAL **:
  g_object_class_install_property: assertion `G_IS_PARAM_SPEC (pspec)'
  failed

Investigation and fix would be nice.

Sample code:

    GdomXPathResult *res;
    char* exp = "//*[@href or @src]";
    GdomDocument *doc = get_dom_document();
    GdomNodeList *els = gdom_document_get_elements_by_tag_name(doc,
"body");
    GdomNode *body = gdom_node_list_item(els, 0);
    GdomXPathNSResolver *resolver =
gdom_document_create_ns_resolver(doc, body);
    GdomNode *node;
    GdomCSSStyleDeclaration *style;
    int i = 0;

    res = gdom_document_evaluate(doc, exp, body, resolver, 0, NULL);
    while(res && (node = gdom_x_path_result_iterate_next(res))) {
        g_object_get(node, "style", &style, NULL);
        gdom_css_style_declaration_set_css_property(style, "border",
"1px dashed red", "");
        gdom_css_style_declaration_set_css_property(style,
"background", "yellow", "");
        g_object_unref(style);
        g_object_unref(node);
        ++i;
    }
    g_object_unref(resolver);
    g_object_unref(body);
    g_object_unref(els);
    g_object_unref(doc);
    g_object_unref(res);

    g_warning("found elements: %d\n", i);

 yehh, it's one of something like 20,000 properties _somewhere_.  tracking it down is going to be one of those lairy by-rote tasks.  i'll see if i can find it but it's not a high priority item, but still important all the same.  thanks for raising it.

WebKitGtk do not have an official DOM bindings yet in the WebKit tree.
