灵格斯LDX,LD2等格式分析
词典格式是这样的
struct {
int Flag; //?LD2,?LDX等标记
byte[16] MD5;//估计是MD5值，LD2转换为LDX时只有前两个字段有变化
byte[4] byteorder;
short majorversion;
short minorversion;
byte[16] ID;
int version;
int flags;
byte[16] MD52;
int unknown1;
int unknown2;
int unknown3;
int unknown4;
} Header; //以上为词典头
int unknown; //总为1
int xmllength; //词典信息的xml长度
[Encrypted("DES")]
byte[xmllength] infoxml; //此xml保存词典信息，由DES加密。
struct {
int dicttype; //取值0,1,2,3,5
[Switch(dicttype)]
union {
[Case(3)] //dicttype=3则为本地词典
{
int dictlength;
[Length(dictlength)]
{
int indexLength; //索引表长度
int uncompressedwordoffset; //单词表在解压后文件的起始位置
int uncompressedxmloffset; //xml在解压后文件的起始位置
int uncompressedxmldatalength; //解压后的xml数据长度
int compresseddatalength;
[Length(indexLength)]
int[] indexes; //索引表
[Length(compresseddatalength)]
struct {
int compressedblockindexlength; //解压后每块数据大小
int uncompressedTotalLength; //解压后总大小
int[] compressedindexes; //每块数据在compresseddata中的起始位置，下一
个为结束位置
byte[] compresseddata;
} compresseddata;
}
}
[Case(0)] //dicttype=0则表示词典结束
}Dictcontent;
} Dict[];
解压后的数据结构：
byte[] wordindexdata;
byte[] worddata;
byte[] xmldata;
每个单词的索引值乘以10就是wordindexdata中的偏移量
在这里读取以下数据结构
struct
{
int WordOffset; //单词在worddata中的偏移量
int XmlOffset; //单词在xmldata中的偏移量
byte Flag1;
byte Flag2; //若为1则表示在worddata中的数据是索引值，读取一个整型，然后用此索引重新计算word和xml
int NextWordOffset;//可计算出word的长度，读取
int NextXmlOffset;//可计算出xml的长度，读取
} WordInfo;
读出的word即为单词
xml为单词释义，是变形的html格式，需要用xslt转换为标准html读取。
解密后词典信息的内容是这种格式的，图标应该是base64编码的。
