So in case of your file the Name Tree for the embedded files does not merely have a leaf node but intermediate nodes, too. (Name Trees are described in ISO 32000-1 section 7.9.6.) Such non-minimal tree structures are seldomly used for embedded files (there generally aren't a lot of embedded files, so the minimal structure is usually sufficient). Therefore, most likely, (and because it was created with iText-generated files in mind) the example code from listing 16.7 assumes a minimal tree here. sselvia wrote > If I change the code to be KIDS and execute the rest of the code the refs > item is null. Intermediate nodes in a name tree (KIDS indicates that you have such a node) are built differently than leaf nodes (using NAMES). Thus, you have to insert code to walk the KIDS nodes until you reach a leaf node. Table 36 – Entries in a name tree node dictionary Kids - array - (Root and intermediate nodes only; required in intermediate nodes; present in the root node if and only if Names is not present) Shall be an array of indirect references to the immediate children of this node. The children may be intermediate or leaf nodes. Names - array - (Root and leaf nodes only; required in leaf nodes; present in the root node if and only if Kids is not present) Shall be an array of the form [key1 value1 key2 value2 … keyn valuen] where each keyi shall be a string and the corresponding valuei shall be the object associated with that key. The keys shall be sorted in lexical order, as described below. Limits - array - (Intermediate and leaf nodes only; required) Shall be an array of two strings, that shall specify the (lexically) least and greatest keys included in the Names array of a leaf node or in the Names arrays of any leaf nodes that are descendants of an intermediate node.
