Problem converting from zip to epub.

[nstock]

I am using calibre 3.10 [64 bit] to convert a htm file to epub format. I have done this type of conversion many times without any problem. However, during this conversion I had the following error appear:



The log shows the following errors:

Conversion error: Failed: Convert book 1 of 1 (什么是改革宗教会)

While I do typically make my mobi file from my epub file, I did try to convert from zip to mobi and ran into the same problem.

I do make the following four changes to the default conversion options:

1. In “Look & Feel” include “Simsun” in the embedded font family box. Or, checkmark the box that says “Embed all fonts in document”.
2. Set the chapter mark to “None” under “Structure Detection”.
3. In the ToC section enter the statement: “//h:p[re:test(@class)]” in box “Level 1 TOC (XPath expression).
4. Under the EPUB Output section checkmark “Preserve cover aspect ratio”. Title the ToC “目录“.

What is the problem? How do I fix the problem?

[kovidgoyal]

The xpath expression you are using for level1 toc is not valid.

Thank you very much. I should have realized that I was putting “//h[re:test(@class)]” in Structure detection instead of in the ToC menu.
