问题 I could read the content of the xml file to a string and use string operations to achieve this, but I guess there is a more elegant way to do this. Since I did not find a clue in the docus, I am sking here: Given an xml (see below) file, how do you count xml tags, like count of author-tags in the example bewlow the most elegant way ? We assume, that each author appears exactly once. <root> <author>Tim</author> <author>Eva</author> <author>Martin</author> etc. </root> This xml file is trivial,

问题 The setup: I have a project that is using CouchDB. The documents will have a field called "tags". This "tags" field is an array of strings (e.g., "tags":["tag1","tag2","etc"]). I am using couchdb-lucene as my search provider. The question: What function can be used to get couchdb-lucene to index the elements of "tags"? If you have an idea but no test environment, type it out, I'll try it and give the result here. 回答1: Well it was quite easy after I figured it out. Please realize that the $

问题 [former title: Is there a way to force a relationship structure on a tag-based organizational methodology?] I have some entities, and they have a series of attributes. Some of the attributes affect what other attributes the entity can have, many of the attributes are organized into groups, and occasionally entities are requited to have certain numbers of attributes from certain groups, or possibly a range of attributes from certain groups. Is there a way to model these sorts of tag-to-tag

问题 I'm beginning with MongoDb and nodejs (using mongoose). I have a collection of Stories , each of them can have one or more Tags , it's something like that: { title: "The red fox", content: "The red fox jumps away...", tags: [ { tagname: "fairytale", user: "pippo" }, { tagname: "funny", user: "pluto" }, { tagname: "fox", user: "paperino" } ] }, ... other stories Now I want to make a tag cloud . It means querying Stories for all tags. In a relational world (e.g. MySQL) I would have a Stories

问题 The JS snippet I created relies on the forloop.counter variable being available within a {% for key, value in data.items %}..{% endfor %} tag. Is there a way to use mathematical operators (*, -, +, /) together with the forloop.counter variable? 回答1: There is the filter add add from the documentation. I'm pretty sure there are no built-in way to use the other mathematical operations over numbers in Django templates. You can always make your own however. It is not always a good idea to do so.

问题 I found two approaches to let an Android app detect and process NFC tags: NfcAdapter.enableReaderMode(activity, callback, flags, extras) and then receive the tag info in the callback. NfcAdapter.enableForegroundDispatch(activity, intent, filters, techLists) and then receive the tag info in the onNewIntent(intent) activity method. I currently use the second approach, however, I recently discovered the enableReaderMode approach and wonder if it's better to use that to process NFC tags. So what

问题 Is it possible to combine the meta description and Open Graph Protocol description… <meta name="description" content="My meta description copy." /> <meta property="og:description" content="My meta description copy." /> …into one when they contain the same content? <meta name="description" property="og:description" content="My meta description copy." /> 回答1: Yes, you can combine them. To test it, I made the simple HTML page below, uploaded it to a server, then ran the page through Facebook's

问题 I can't seem to find a way to select the beginning of a bracket and jump to the end of it through some key combination or something in VS Code . For example, in atom , this is done with Ctrl + m . I know there is a way to jump to the beginning and end of a bracket or curlybraces with Cmd + Shift + \ but that does not work for tags. Any ideas? 回答1: It is possible to do, but either using Ctrl + Shift + P -> " Emmet: Go to Matching Pair " or by manually setting a shortcut for it ( Ctrl + K Ctrl
