text() and node() are node tests, in XPath terminology (compare). Node tests operate on a set (on an axis, to be exact) of nodes and return the ones that are of a certain type. When no axis is mentioned, the child axis is assumed by default. There are all kinds of node tests: node() matches … Read more
I. Use this single XPath expression: translate(normalize-space(/tr/td/a), ‘ ‘, ”) Explanation: normalize-space() produces a new string from its argument, in which any leading or trailing white-space (space, tab, NL or CR characters) is deleted and any intermediary white-space is replaced by a single space character. translate() takes the result produced by normalize-space() and produces a … Read more
This will find the first instance of an element named bar and return the value of the attribute key. In [52]: import xml.etree.ElementTree as ET In [53]: xml=ET.fromstring(contents) In [54]: xml.find(‘./bar’).attrib[‘key’] Out[54]: ‘value’
Try this: //obtain Document somehow, doesn’t matter how DocumentBuilder b = DocumentBuilderFactory.newInstance().newDocumentBuilder(); org.w3c.dom.Document doc = b.parse(new FileInputStream(“page.html”)); //Evaluate XPath against Document itself XPath xPath = XPathFactory.newInstance().newXPath(); NodeList nodes = (NodeList)xPath.evaluate(“/html/body/p/div[3]/a”, doc, XPathConstants.NODESET); for (int i = 0; i < nodes.getLength(); ++i) { Element e = (Element) nodes.item(i); } With the following page.html file: <html> <head> … Read more
From the documentation of XPath ( http://www.w3.org/TR/xpath/#location-paths ): child::* selects all element children of the context node child::text() selects all text node children of the context node child::node() selects all the children of the context node, whatever their node type So I guess your answer is: $doc/PRESENTEDIN/X/child::node() And if you want a flatten array of … Read more
I’d probably be inclined to go with Bartek’s* namespace solution, but a general xpath solution is: //*[local-name()=’ProjectGuid’] **since Bartek’s answer has disappeared, I recommend Teun’s (which is actually more thorough)*
Wikipedia is a good place to start for questions like this. Generally, XPath is a language used to succinctly pinpoint exact XML nodes in a DOM. XQuery is a superset of XPath that also provides FLWOR syntax, which is SQL-like. Finally, XPointer includes XPath, but also provides a simpler position-based addressing scheme. Of course, you … Read more
I just found this: http://stedolan.github.io/jq/ “jq is a lightweight and flexible command-line JSON processor.” 2014 update: @user456584 mentioned: There’s also the ‘json’ command (e.g. ‘jsontool’). I tend to prefer it over jq. Very UNIX-y. Here’s a link to the project: github.com/trentm/json – in the json README at http://github.com/trentm/json there is a long list of similar … Read more
As Filburt says; but also note that it’s usually better to write test=”not(Count=”N/A”)” If there’s exactly one Count element they mean the same thing, but if there’s no Count, or if there are several, then the meanings are different. 6 YEARS LATER Since this answer seems to have become popular, but may be a little … Read more
