Haxe与XPath有友谊吗?

我需要通过它的XPath获取一些XML节点,我该怎么做?

我尝试使用此库https://github.com/djcsdy/haxe-xpath,但错误https://github.com/djcsdy/haxe-xpath/issues/26

对于我的任务来说,xml-fast并不是一个好的解决方案,因为它看起来更糟糕"比起XPath,我想:

js(xpath):

xml_doc.get('//project/classpaths/class[@path="' + src_path + '"]')
haxe(xml-fast):

(new Fast(xml_doc))).node.project.node.classpaths.nodes.class.filter(function (x:Fast) return x.has.path ? x.att.path == src_path : false)

感谢

答案 0 :(得分:2)

结果发现有两个库,都需要一些修复。

1。 "Haxe XPath"

只有当克隆目录“haxe-xpath / src / xpath”进入您的源(haxelib repo不包含此库)时才可以使用它。

此库需要一些修复:thisthis

示例(删除第一个找到的元素):

package;

import xpath.XPathHx;
using Lambda;

class Main {
    public static function main () {
        var xml = Xml.parse("<a> <b> <c>qwe</c> <c>asd</c> </b> </a>");
        trace(xml.toString());

        var xpExpr = new XPathHx("//a/b/c"); // create new XPath expression object
        var result = xpExpr.selectNodes(xml).array()[0]; // get first element from array of founded xml-nodes

        result.parent.removeChild(result); // remove selected node from xml-tree
        trace(xml.toString());
    }
}

2。 "xmlTools"

可以使用haxelib安装:

haxelib install xmlTools
haxelib install composure

Some fix was needed for this library (in my task)和一个nuance for xpath

示例(删除第一个找到的元素):

package;

import xmlTools.XPath;
using Lambda;

class Main {
    public static function main () {
        var xml = Xml.parse("<a> <b> <c>qwe</c> <c>asd</c> </b> </a>");
        trace(xml.toString());

        var xpath  = new XPath(); // create new XPath expression object
        var result = xpath.resolve(xml, "*/a/b/c").array()[0]; // get first element from array of founded xml-nodes

        result.parent.removeChild(result); // remove selected node from xml-tree        
        trace(xml.toString());
    }
}
