Write directly to file from BaseX GUI

由 孤街醉人 提交于 2020-08-04 17:18:36
问题 I wrote an XQuery expression that has a large result of about 50MB and takes a couple of hours to compute. I execute it in the BaseX GUI, but this is a little inconvenient: it crops the result to a result window, which I then have to save. At this time, BaseX becomes unresponsive and may crash. Is there a way to directly write the result to a file? 回答1: Have a look at BaseX' file module, which provides broad functionality to read and write from files and traverse the file system. For you,

一、简介 　　XPath 是一门在 XML 文档中查找信息的语言。XPath 可用来在 XML 文档中对元素和属性进行遍历。XPath 是 W3C XSLT 标准的主要元素，并且 XQuery 和 XPointer 都构建于 XPath 表达之上。 二、安装 pip3 install lxml 三、使用 选取节点 常用的路径表达式 nodename（表达式、） 选取nodename节点的所有子节点 （描述） xpath(‘//div’) 选取了div节点的所有子节点（实例） / 从根节点选取 xpath(‘/div’) 从根节点上选取div节点 // 选取所有的当前节点，不考虑他们的位置 xpath(‘//div’) 选取所有的div节点 . 选取当前节点 xpath(‘./div’) 选取当前节点下的div节点 .. 选取当前节点的父节点 xpath(‘..’) 回到上一个节点 @ 选取属性 xpath（’//@calss’）选取所有的class属性 谓词：被嵌在方括号内，用来查找某个特定的节点或包含某个制定的值的节点 xpath(‘/body/div[1]’)   选取body下的第一个div节点 xpath(‘/body/div[last()]’)   选取body下最后一个div节点 xpath(‘/body/div[last()-1]’)

问题 Working with latest MarkLogic-10.0-2.1-amd64 on win10 In a xquery I invoke an xslt transformation: xdmp:xslt-invoke("/tidy2html.xslt", doc($docurl)) And within that xslt transformation, I want to retrieve an additional doc (with uri sdp/xref.xml) from the content database where $docurl resides. <xsl:variable name="xref-uri" select="doc('sdp/xref.xml')"/> I'm sure by looking at query console that doc('sdp/xref.xml') exists using XQuery context pointed to the content database. In XSLT I'm a bit

How do I use RESTXQ with BaseX for a simple web app?

由 耗尽温柔 提交于 2020-07-22 12:19:12
问题 I'm trying to create a really basic web app that lets a user upload an xml file with a form, runs an XQuery script which I already have written as a function, and returns the result. I have BaseX running on Tomcat, but for the life of my I cannot understand RESTXQ even though I have a lot of experience with complex XQuery scripts. The BaseX documentation has been no help (http://docs.basex.org/wiki/RESTXQ). What is the basic architecture? From what I can see, its all keyed on this restxq.xqm
