C语言 Oracle Outside In Parse SCCCA content

Question

我正在使用文档Oracle Outside In来输出pdf文档的文本内容。

我正在使用以下参数从的内容访问传递到CASample.c文件的主函数https://www.oracle.com/middleware/technologies/outside-in-technology-downloads.html#

C:adobe-acrobat.pdf -u C:adobe-acrobat.txt";

这给了我以下格式的文本。

SCCCA_TEXT: dwSubType = 0x08020001, Number of Characters = 8, Character Set = 0x00030100.
Outside 
SCCCA_TEXT: dwSubType = 0x08020001, Number of Characters = 3, Character Set = 0x00030100.
In 
SCCCA_TEXT: dwSubType = 0x08020001, Number of Characters = 8, Character Set = 0x00030100.
Unlocks 
SCCCA_TEXT: dwSubType = 0x08020001, Number of Characters = 9, Character Set = 0x00030100.
Business 
SCCCA_TEXT: dwSubType = 0x08020001, Number of Characters = 10, Character Set = 0x00030100.
Documents 
SCCCA_TEXT: dwSubType = 0x08020001, Number of Characters = 4, Character Set = 0x00030100.
for 
SCCCA_TEXT: dwSubType = 0x08020002, Number of Characters = 1, Character Set = 0x00030100.

那么，如何在没有元数据的情况下只从中获取文本呢？我只需要Outside In Unlocks Business Documents for，而不是整个元数据内容，或者我必须制作自己的解析器来获取这些数据吗？

在他们下载的文件中也有一个tademo.vcxproj，它可以提取文本。它是一个桌面应用程序，您可以将其转换为库。

在将其转换为库之后，我在tademo.c文件中创建了以下函数，该函数将接受输入文件并将文本文件导出为输出。

int callableMain(char* inputPath, char* outputPath) {
strncpy(szInputPath,inputPath, PATHSIZE);
DAInitEx(SCCOPT_INIT_NOTHREADS, OI_INIT_DEFAULT);
DoTextClose();
dwBlockNum = 0;
DoTextOpen(1);
DoSaveTextAs(outputPath);
DoTextClose();
return 1;
}
