使用Delphi7 TClientDataSet:是否可以将XML内容以缩进格式保存? [英] Using Delphi7 TClientDataSet: is it possible to have it save its XML contents in an indented format?
问题描述
我正在使用Delphi7 TClientDataSet 读取和写入某些数据的XML文件.
I am using Delphi7 TClientDataSet to read and write XML files for some of my data.
但是，当我想在程序外部浏览此文件时(在Windows资源管理器中双击XML)，我得到了在文本内容中发现一个无效字符.错误处理资源"-即使数据可以在Delphi中正常读取和写入.
However, when I want to browse this outside the program (double clicking the XML in Windows Explorer) I get the 'An invalid character was found in text content. Error processing resource' - even though the data reads and writes fine from within Delphi.
是否有一种方法可以强制 TClientDataSet 以缩进方式而不是一行写入内容?
Is there a way to force TClientDataSet to write its contents in an indented way instead of in one line?
这样，我可以轻松地将其打开到文本编辑器中，并找到将触发上述错误的字符.
That way I could easily open it into a text editor and find what character will trigger the above error.
无论如何:我发现使用CR/LF编写XML文件和缩进仍然更加清晰.
Anyway: I find it much clearer for an XML file to be written with CR/LF and indents anyway.
推荐答案
这是因为正确的编码(例如<?xml version ="1.0" encoding ="UTF-8"?> )尚未在输出文件中指定，但其中包含一些编码不兼容的字符.
It's because the proper encoding (like <?xml version="1.0" encoding="UTF-8"?>) has not be specified in your output file, yet it contains some characters with an incompatible encoding.
As RRUZ mentioned, specifying explicitly the TDataPacketFormat as dfXMLUTF8 when writing the file will most certainly solve the 'Invalid Character' error, as it will write the encoding tag first:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <DATAPACKET Version="2.0">[...]
You can also add the encoding manually at the beginning of the file for already existing files.
对于可读格式，某些读者可以阅读原始的一线内容并为您进行格式设置(浏览器如FireFox或Internet Exporer，以及XML编辑器如
As for the readable formatting, some readers can read the raw one-liner and do the formatting for you (browsers like FireFox or Internet Exporer, and XML editors like XMLNotePad)
