在Sulu模板中包含带有xpointer的属性

问题描述

我已经设置了一些Sulu模板,并且能够使用此处描述的方法将整个文件的内容包含在多个模板中:

https://docs.sulu.io/en/2.1/book/templates.html

我正在使用:

<xi:include href="fragments/common-properties.xml"/

这很好用

然后我尝试使用xpointer方法包括另一个模板的属性(为了使我可以在一个文件中的所有模板中包含一堆通用属性,并且还要为各个模板定义特定的属性)

我的根模板在这里:(root-page-test.xml)

<?xml version="1.0" ?>
<template xmlns="http://schemas.sulu.io/template/template"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xmlns:xi="http://www.w3.org/2001/XInclude"
          xsi:schemaLocation="http://schemas.sulu.io/template/template http://schemas.sulu.io/template/template-1.0.xsd">

    <key>my-account-page-react</key>

    <view>pages/my-account-page-react</view>
    <controller>App\Controller\Headless\HeadlessWebsiteController::indexAction</controller>
    <cacheLifetime>604800</cacheLifetime>

    <meta>
        <title lang="en">Test including properties</title>
    </meta>
    
    <properties>
        <property name="header" type="text_line">
            <meta>
                <title lang="en">Header</title>
            </meta>
        </property>

        <xi:include href="include.xml"
            xpointer="xmlns(sulu=http://schemas.sulu.io/template/template)
                      xpointer(/sulu:properties/sulu:property)"/>

    </properties>
    
    

    
</template>

包含要包含的属性的模板在此处:(include.xml)

<?xml version="1.0" ?>
<template xmlns="http://schemas.sulu.io/template/template"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xmlns:xi="http://www.w3.org/2001/XInclude"
          xsi:schemaLocation="http://schemas.sulu.io/template/template http://schemas.sulu.io/template/template-1.1.xsd">

    <key>include-test</key>
    
    <view>pages/my-account-page-react</view>
    <controller>App\Controller\Headless\HeadlessWebsiteController::indexAction</controller>
    <cacheLifetime>604800</cacheLifetime>
    
    <meta>
        <title lang="en">Test include</title>
    </meta>
    
    <properties>
        
        <property name="url" type="resource_locator" mandatory="true">
            <meta>
                <title lang="en">Resourcelocator</title>
            </meta>

            <tag name="sulu.rlp"/>
        </property>
        
        <property name="title" type="text_line" mandatory="true"> 
            <meta>
                <title lang="en">Title</title> 
            </meta>
            <params>
                <param name="headline" value="true"/> 
            </params>

            <tag name="sulu.rlp.part"/>
        </property>

        <property name="article" type="text_editor">
            <meta>
                <title lang="en">Article</title>
            </meta>
        </property>

    </properties>
</template>

在加载管理界面时,我从ajax请求之一中收到以下错误:

[ERROR 1612] XPointer evaluation failed: #xmlns(sulu=http://schemas.sulu.io/template/template) xpointer(/sulu:properties/sulu:property) (in C:\xampp\htdocs\<vhost>/config/templates/pages\root-page-test.xml - line 26,column 0)↵[ERROR 1604] could not load include.xml,and no fallback was found (in C:\xampp\htdocs\<vhost>/config/templates/pages\root-page-test.xml - line 26,column 0)↵[ERROR 1871] Element '{http://www.w3.org/2001/XInclude}include': This element is not expected. (in C:\xampp\htdocs\<vhost>/config/templates/pages\root-page-test.xml - line 26,column 0)

两个文件都在同一目录中

我要去哪里错了?

解决方法

您的XPointer是不正确的,因为如果您以/开头,则意味着您是从文档的根目录开始的。因此,如果您执行/sulu:properties/sulu:property,则XPointer会假定您要包含的文件的根目录处应该有一个properties标记。我的建议是您制作一个这样的文件(this is also shown in the last code snippet in our documentation in this heading):

<?xml version="1.0" ?>
<properties xmlns="http://schemas.sulu.io/template/template"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://schemas.sulu.io/template/template http://schemas.sulu.io/template/template-1.1.xsd">
    <property name="url" type="resource_locator" mandatory="true">
        <meta>
            <title lang="en">Resourcelocator</title>
        </meta>

        <tag name="sulu.rlp"/>
    </property>
        
    <property name="title" type="text_line" mandatory="true"> 
        <meta>
            <title lang="en">Title</title> 
        </meta>
        <params>
           <param name="headline" value="true"/> 
        </params>
        <tag name="sulu.rlp.part"/>
    </property>

    <property name="article" type="text_editor">
        <meta>
            <title lang="en">Article</title>
        </meta>
    </property>
</properties>

这样,您还可以摆脱不必要的元素,例如viewcontroller标签,在这种情况下不需要。

或者,您也可以调整包含的XPointer:

<xi:include href="include.xml" xpointer="xmlns(sulu=http://schemas.sulu.io/template/template)xpointer(/sulu:template/sulu:properties/sulu:property)" />

在xpointer的开头请注意附加的sulu:template
