PyXB - AssertionError:http://www.w3.org/1999/xhtml中没有元素绑定

我正在尝试使用PyXB为WSDL生成绑定,并且它在标题中给出了AssertionError异常。

根据PyXB文档,我的理解是,http://www.w3.org/1999/xhtml的包存档包含在PyXB中。然而,似乎有些不对劲。它要么没有被使用,要么内容不正确。

我使用以下命令行尝试生成绑定:

python c:\Python27\Scripts\pyxbgen.py --wsdl-location=http://xx.xxx.xxx.xxx/YYY.asmx?WSDL --module=client --write-for-customization

追溯:

Traceback (most recent call last):
File "c:\Python27\Scripts\pyxbgen.py", line 51, in <module> generator.resolveExternalSchema()

assert 'elementBinding' in elt_en.namespace()._categoryMap(), 'No element bindings in %s' % (elt_en.namespace(),)
AssertionError: No element bindings in http://www.w3.org/1999/xhtml

另外,我将PYXB_ARCHIVE_PATH环境变量设置为:

C:\Python27\Lib\site-packages\pyxb\bundles\common\raw

我不确定这是否是正确的方法。我也尝试过指定--archive-path命令行选项,但我得到了同样的错误。

1 个答案:

答案 0 :(得分:0)

可能你需要使用:

--archive-path=${PYXB_ROOT}/pyxb/bundles/common//:+

作为论点。这将首先在公共包中递归搜索可用的命名空间,然后包括任何其他搜索路径。有一个example in the manual与此接近。
