How do I select an XML node with the longest child #text node value with XPath?

阅读更多关于 How do I select an XML node with the longest child #text node value with XPath?

I've used XPath to select the node with the largest integer id value before using this query: //somenode[not(@id <= preceding::somenode/@id) and not(@id <= following::somenode/@id)] I was hoping that I could do something similar like: //entry[not(string-length(child::text()) <= string-length(preceding::entry/child::text())) and not(string-length(child::text()) <= string-length(following::entry/child::text()))] But it returns a bunch of nodes instead of just one. Sample XML: <xml> <entry>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</entry> <entry>Nam dignissim mi a massa mattis

Find all text nodes

阅读更多关于 Find all text nodes

I'm trying to write a bookmarklet that calls the function doSomething(textNode) on all instances of visible text on the document. doSomething() , just for fun, replaces every word with "derp" by replacing the textContent of the textNode passed into it. However, this makes some textNodes that are empty to have words in them, so it breaks the web page. Is there a way to call doSomething() on only every textNode that has words in it? function recurse(element) { if (element.childNodes.length > 0) for (var i = 0; i < element.childNodes.length; i++) recurse(element.childNodes[i]); if (element

JavaScript: Add elements in textNode

阅读更多关于 JavaScript: Add elements in textNode

I want to add an element to a textNode. For example: I have a function that search for a string within element's textNode. When I find it, I want to replace with a HTML element. Is there some standard for that? Thank you. palswim You can't just replace the string, you'll have to replace the entire TextNode element, since TextNode elements can't contain child elements in the DOM. So, when you find your text node, generate your replacement element, then replace the text node with a function similar to: function ReplaceNode(textNode, eNode) { var pNode = textNode.parentNode; pNode.replaceChild

I'm developing a Google Chrome extension that allows you to automatically apply a highlighting CSS rule to a word that you choose. I have the following code var elements = document.getElementsByTagName('*'); for (var i=0; i<elements.length; i++) { var element = elements[i]; for (var j=0; j<element.childNodes.length; j++) { var node = element.childNodes[j]; if(node.nodeType === 3) { var text = node.nodeValue; var fetchedText = text.match(/teste/gi); if(fetchedText) { var replacedText = element.innerHTML.replace(/(teste)/gi, "$1"); if (replacedText

my HTML code : <body>Firebrand will tend to burn any bricks out there. so the best idea is to ignore any active firebrand if you are a bricks. Otherwise, you can challenge a firebrand if you have the proper quality to keep up with their latest technology. And don't mess up with firebrand if you are a robber.</body> I want to find any "firebrand" inside the body and replace it with firebrand with jQuery Just recurse through the DOM, while using: .replace(/(firebrand)/gi, '$1') on each text content. function firebrand($el) { $el

Is there a 4096 character limit for JavaScript XML text nodes?

阅读更多关于 Is there a 4096 character limit for JavaScript XML text nodes?

How is it that I always get only the first 4096 chars of a valid XML text node? (using JavaScript...) is a text node limited? Yes. Some browsers limit to 4096, and split longer texts into multiple text node children of the parent element. If you look at the source to Apache CXF you will find some utility Java script to deal with this, if no place else. // Firefox splits large text regions into multiple Text objects (4096 chars in // each). Glue it back together. function getNodeText(node) { var r = ""; for (var x = 0;x < node.childNodes.length; x++) { r = r + node.childNodes[x].nodeValue; }
