将 Web 表单数据映射到重复的 XML 元素 [英] Mapping web form data to repeated XML elements

问题描述

我在网上到处寻找这个问题的答案，但在任何地方都找不到.

I have gone all over the web looking for an answer to this, and have not been able to find one anywhere.

我正在尝试构建一个使用 XSLT 生成 XML 数据的 Web 表单.我把它建立在做同样事情的其他形式上，并且已经让小的测试结构正常工作.但是，当我尝试将其映射到重复元素时遇到了各种问题.

I'm trying to build a web form that uses XSLT to generate XML data. I'm basing it on other forms that do the same thing, and have gotten small test structures to work fine. However, I am running into all sorts of problems when I try to map it to repeated elements.

这是我所拥有的快速概览.我有一个与此类似的 XSLT 文件(免责声明:为简洁起见排除了行；此外，这些不是实际的字段名称):

Here's a quick overview of what I have. I have an XSLT file that looks similar to this (disclaimer: lines excluded for brevity; also, these are NOT the actual field names):

<someForm:Name></someForm:Name>
<someForm:Address></someForm:Address>
<someForm:Plan>
    <someForm:Step></someForm:Step>
    <someForm:Description></someForm:Description>
</someform:Plan>

我还有一个关联的架构，如下所示:

I also have an associated schema that looks like this:

<xs:element name="Name" />
<xs:element name="Address" />
<xs:element name="Plan" maxOccurs="10">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="Step" />
            <xs:element name="Description" />
        </xs:sequence>
    </xs:complexType>
</xs:element>

记下 Plan 元素中的maxOccurs='10'"！这就是我遇到问题的地方！

我写了一个看起来像这样的表单(同样，基于其他工作表单):

I wrote a form (again, based on other, working forms) that looks like this:

<input type="text" id="getName" xpath="/*[local-name()='Name']">
<input type="text" id="getAddress" xpath="/*[local-name()='Address']">
<table>
    <tr><th>Step</th><th>Description</th></tr>
    <tr>
        <td><input type="text" id="getStep1" xpath="/*[local-name()='Plan']/*[local-name()='Step']"></td>
        <td><input type="text" id="getDesc1" xpath="/*[local-name()='Plan']/*[local-name()='Description']"></td>
    </tr>
</table>

这很好用；我可以提交数据，它会根据需要创建 XML.

This works fine; I am able to submit data, and it creates the XML as I want.

但是，这是我的问题:我正在尝试编写我的设置，以便它最多可以容纳十行(根据 maxOccurs 设置).当我尝试这样做时它不起作用:

However, here is my problem: I am trying to write my setup so it can accommodate up to ten rows (as per the maxOccurs setting). It will NOT work when I try to do this:

    <tr>
        <td><input type="text" id="getStep1" xpath="/*[local-name()='Plan']/*[local-name()='Step']"></td>
        <td><input type="text" id="getDesc1" xpath="/*[local-name()='Plan']/*[local-name()='Description']"></td>
    </tr>
    <tr>
        <td><input type="text" id="getStep2" xpath="/*[local-name()='Plan']/*[local-name()='Step']"></td>
        <td><input type="text" id="getDesc2" xpath="/*[local-name()='Plan']/*[local-name()='Description']"></td>
    </tr>

这给我带来了各种各样的问题，这取决于我如何调整它.有时，它不保存任何数据(对于步骤和描述)；有时，它会为两行保存相同的数据.

This gives me all sorts of problems, depending on how I tweak it. Sometimes, it does not save any data (for Step and Description); sometimes, it saves the same data for both rows.

我找不到任何文档来解释它是如何工作的.我已经调整了 XSLT、HTML 和 schema，但都无济于事.这让我很沮丧.

I have not been able to find any documentation that explains how this works. I've tweaked the XSLT, HTML, and schema, all to no avail. And this is frustrating the crap out of me.

有人知道如何解决这个问题吗?

Does anyone have any insight as to how to solve this?

注意:这与我之前提出的另一个问题直接相关:CreatingXSLT 节点动态/多个 XSLT 节点

Note: this is directly related to another question that I asked earlier: Creating XSLT nodes dynamically/multiple XSLT nodes

提前感谢您的任何帮助...

Thanks in advance for any assistance . . .

推荐答案

以下是我最终实现此功能的方法:

Here's how I finally got this to work:

    <tr>
        <td><input type="text" id="getStep1" xpath="/*[local-name()='Plan'][1]/*[local-name()='Step']"></td>
        <td><input type="text" id="getDesc1" xpath="/*[local-name()='Plan'][1]/*[local-name()='Description']"></td>
    </tr>
    <tr>
        <td><input type="text" id="getStep2" xpath="/*[local-name()='Plan'][2]/*[local-name()='Step']"></td>
        <td><input type="text" id="getDesc2" xpath="/*[local-name()='Plan'][2]/*[local-name()='Description']"></td>
    </tr>

如果您查看 xpath，请注意计划"之后的 [1] 和 [2].当我将它们包含在 xpath 中时，它没有问题.

If you look at the xpath, notice the [1] and [2] after "Plan." When I included those with the xpath, it worked with no problem.
