火狐浏览器+Firebug+FirePath测试Xpath

由 梦想与她 提交于 2020-03-24 08:14:08
前言 抓取网页数据时使用HtmlAgilityPack分析，需要通过xpath定位页面元素。如果有个xpath的生成和验证工具就事半功倍了，火狐浏览器插件FirePath配合Firebug就能完美实现。 FirePath介绍如下： FirePath is a Firebug extension that adds a development tool to edit, inspect and generate XPath 1.0 expressions, CSS 3 selectors and JQuery selectors.With FirePath you can: * Edit XPath expressions, CSS3 selectors and JQuery selectors (Sizzle selector engine) with auto completion for XPath (using TAB or up and down arrows). * Evaluate the expression/selector on any HTML or XML documents. * Display the result of evaluations in a Firebug-like DOM tree. * Highlight the results

Python ElementTree find() using namespaces

由 时光怂恿深爱的人放手 提交于 2020-03-24 00:38:02
问题 I am attempting to use Python’s ElementTree to parse and modify an xml file. The confusion comes with the XML Namespace. I can use the findall and finditer to get all of the servers names. However, I can't get the xpath query to work to find a specific server. instead the find just brings back the parent element. What I need to do is find the correct server by the “name” or “machine” element and modify the “arguments”. <? xml version=’1.0’ encoding=’UTF-8’?> <domain xmlns=”http://xmlns.oracle

【复习】selenium中用Xpath定位

由 佐手、 提交于 2020-03-23 18:23:34
一、基础属性定位 id/class/name 百度一下按钮：//input[@id="su"]* text()定位 更多产品链接定位：//*[text()="更多产品"] 二、索引过滤 当定位出现多个兄弟结果时，可以索引过滤，坐标从1开始，最后用last() 新闻链接：//a[@class="mnav"][1] 学术链接 //a[@class="mnav"][last()] 三、逻辑运算定位 新闻链接：//a[@class="mnav" and text()="新闻"] 四、轴定位（轴名称::节点名称） ancestor：祖先节点包括父节点 parent：父节点 preceding-sibling: 选取当前节点之前的所有同级节点（html页面位置） preceding：当前节点之前的所有节点（html页面位置） following-sibling：当前节点之后的所有兄弟节点（html页面位置） following：当前元素节点之后的所有节点（html页面位置） 例：查找地图的兄弟节点新闻： //a[@name="tjtrmap"]/parent::div/[text()="新闻"] 来源： 51CTO 作者： wx57a1620925627 链接： https://blog.51cto.com/11926720/2481077

SQL Server XML querying: Query multiple child elements with same name

由 ￡可爱￡侵袭症＋ 提交于 2020-03-23 09:51:43
问题 In a previous question I wanted to know how I can use SQL to JOIN different XML elements based on an identifier. I was provided with several nice solutions as you can see here. Now I am in the process of adapting this solution to my actual data. Unfortunately I stumbled upon a new obstacle that was not present in the minimum viable example I provided in the linked question. In my actual data I also have several child elements of the same name. See the element <subElement> in the following

XPath: select node that contains normalized text, excluding ancestor nodes

由 心不动则不痛 提交于 2020-03-23 08:01:58
问题 I'm looking for a performant, generic query to select "The quick brown fox jumped over the lazy dog." similar to how a simple CMD+C would copy the text. It seems that I need to use the textContent , but my XPath is also selecting the ancestors (up to body), rather than just the first (few) ancestors. How can I limit the scope? example node.textContent " The quick brown fox jumped over the lazy dog. " Run Code Snippet → Full Page → Follow instruction <div id='dont-select-this' style='text

利用updatexml()报错注入mysql

由 徘徊边缘 提交于 2020-03-22 20:16:57
基本介绍一下updatexml() updatexml(XML_document, XPath_string, new_value) XML_document是文档对象的名称 XPath_string是XPath格式的字符串( 如果XPath_string不是XPath格式，则会报错并显示出XPath_string的值 ) new_value替换查找到的数据 XPath语法介绍:https://blog.csdn.net/dearbaba_8520/article/details/81557827 再看看常用的语句 updatexml(1,concat(1, payload ),1)。 concat()函数用于将多个字符串连接成一个字符串,目的是让拼接后的字符串不符合XPath格式使其报错,显示出要查的对象。 最终的目的是使其报错，至于拼接的值多种多样，并不局限于1。 以sqli-labs为例: 可以看到，把payload位置改为database()后报错返回了当前数据库的名称 之后按照注入流程爆出表名，字段名即可 来源： https://www.cnblogs.com/remon535/p/12547932.html
