xml - XPath NodeSet in Java -

-

मेरे पास इस कोड को ग्रहण है 

  नोडसेट नोड्स = (नोडसेट) xPath.evaluate ( अभिव्यक्ति, इनपुट स्रोत, XPathConstants.NODESET);

और इसके द्वारा मुझे नोडसेट पर समय त्रुटि संकलन देना है।

यह वह चीज है जिसे मैंने आयात किया है। क्या आप मुझे बता सकते हैं कि ऐसा क्यों है? 

  आयात javax.xml.xpath। *; आयात org.xml.sax.InputSource; आयात करें java.io.File; आयात करें java.io.FileInputStream; आयात java.io.FileNotFoundException; Import java.util। *;

जैसा कि संकेत दिया गया है कि नोडसेट मानक पुस्तकालयों का हिस्सा नहीं है। हालांकि, नोडसेट मैप्स से एक नोडलिस्ट के लिए, इसलिए आप इसका इस्तेमाल केवल इसके बजाय कर सकते हैं। तो यह हो जाएगा:

<पूर्व> नोडलिस्ट नोड्स = (नोडलिस्ट) xPath.evaluate (अभिव्यक्ति, इनपुट स्रोत, XPathConstants.NODESET);

आपको org.w3c.dom.NodeList आयात करना होगा।

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
