Question

我正在尝试做一些关于如何从Informatica Powercenter中已经完成的Mappings轻松制作文档的研究，并且由于不同选项的数量，最初的方法对我来说很难。这里遵循的方法是根据需要多次访问映射中的每个框，将信息复制到word文档，格式化，每周执行几千次。

现在，我认为解决方案的想法很低：将映射导出到XML，使用脚本（或程序，我已经尝试过几次excel，unseccesfully）解析所述XML更容易复制 - 粘贴，这样可以改善我的生活。

XML看起来像这样（简化为尽可能少的行来做一个例子，它可能不是100％有效但原始的XML显然也是值得分配的东西，我把它放在与任何东西无关的东西上价值，而不是每一次字符串）：

Type 1 Document:

   <!DOCTYPE POWERMART SYSTEM "ValueAssigned">
<POWERMART CREATION_DATE="ValueAssigned" REPOSITORY_VERSION="ValueAssigned">
<REPOSITORY NAME="ValueAssigned" VERSION="ValueAssigned" CODEPAGE="ValueAssigned" DATABASETYPE="ValueAssigned">
<FOLDER NAME="ValueAssigned" GROUP="" OWNER="ValueAssigned" SHARED="ValueAssigned" DESCRIPTION="ValueAssigned" PERMISSIONS="ValueAssigned" UUID="ValueAssigned">
    <CONFIG DESCRIPTION ="ValueAssigned" ISDEFAULT ="YES" NAME ="ValueAssigned" VERSIONNUMBER ="ValueAssigned">
        <ATTRIBUTE NAME ="Field1" VALUE =""/>
        <ATTRIBUTE NAME ="Field2" VALUE ="NO"/>
    <WORKFLOW DESCRIPTION ="" ISENABLED ="ValueAssigned" ISRUNNABLESERVICE ="ValueAssigned" ISSERVICE ="ValueAssigned" ISVALID ="ValueAssigned" NAME ="ValueAssigned" REUSABLE_SCHEDULER ="ValueAssigned" SCHEDULERNAME ="ValueAssigned" SERVERNAME ="ValueAssigned" SERVER_DOMAINNAME ="ValueAssigned" SUSPEND_ON_ERROR ="ValueAssigned" TASKS_MUST_RUN_ON_SERVER ="ValueAssigned" VERSIONNUMBER ="ValueAssigned">
        <SCHEDULER DESCRIPTION ="" NAME ="SchedulerName" REUSABLE ="ValueAssigned" VERSIONNUMBER ="ValueAssigned">
            <SCHEDULEINFO SCHEDULETYPE ="ONDEMAND"/>
        </SCHEDULER>
        <TASK DESCRIPTION ="ValueAssigned" NAME ="Start" REUSABLE ="NO" TYPE ="Start" VERSIONNUMBER ="1"/>
        <SESSION DESCRIPTION ="ValueAssigned" ISVALID ="ValueAssigned" MAPPINGNAME ="ValueAssigned" NAME ="ValueAssigned" REUSABLE ="ValueAssigned" SORTORDER ="ValueAssigned" VERSIONNUMBER ="ValueAssigned">
            <SESSTRANSFORMATIONINST ISREPARTITIONPOINT ="ValueAssigned" PARTITIONTYPE ="ValueAssigned" PIPELINE ="ValueAssigned" SINSTANCENAME ="ValueAssigned" STAGE ="ValueAssigned" TRANSFORMATIONNAME ="ValueAssigned" TRANSFORMATIONTYPE ="Target Definition">
                <ATTRIBUTE NAME ="ValueAssigned" VALUE ="ValueAssigned"/>
                <ATTRIBUTE NAME ="ValueAssigned" VALUE ="ValueAssigned"/>
            </SESSTRANSFORMATIONINST>

因此，如果我们专注于任何一个标签，例如

<CONFIG DESCRIPTION ="Default session configuration object" ISDEFAULT ="YES" NAME ="default_session_config" VERSIONNUMBER ="29">
        <ATTRIBUTE NAME ="Field1" VALUE =""/>
        <ATTRIBUTE NAME ="Field2" VALUE ="NO"/>

我们可以看到有一个Tag，CONFIG DESCRIPTION，其次是一些属性名称。我正在考虑的其中一个选项有点天真，但是如果我要将它转到列，excel或类似的，我可以看到一个带有根标签的行，并且在那个不同的类别下，以及那个细分到达我能看到的地方：好的这是标签，这是一个包含所有值的列，我将它复制到我的word文档并称之为一天。因为在XML中有300到900行之间的任何地方，并且它既不容易看到也不容易使用，因为引号，常量标记，列没有对齐，因为行不具有相同的长度（所以我不能使用列模式）...

我放了另一种类型的文件，以防它更清楚地了解信息的差异，以及为什么我不直接跳进我自己的解析器：

  <?xml version="ValueAssigned" encoding="ValueAssigned"?>
<!DOCTYPE POWERMART SYSTEM "ValueAssigned">
<POWERMART CREATION_DATE="ValueAssigned" REPOSITORY_VERSION="ValueAssigned">

我过去做过类似的事情：将xml文件转换为平坦的TXT文件。您的一个问题是XML是一种具有类似列表结构的嵌套格式。

有一件事就是以这种方式压扁它：

<CONFIG DESCRIPTION ="Default session configuration object" ISDEFAULT ="YES" NAME ="default_session_config" VERSIONNUMBER ="29">
        <ATTRIBUTE NAME ="Field1" VALUE =""/>
        <ATTRIBUTE NAME ="Field2" VALUE ="NO"/>
</CONFIG>

变为

CONFIG.DESCRIPTION = "Default session configuration object"
CONFIG.ISDEFAULT = ="YES"
CONFIG.NAME ="default_session_config"
CONFIG.VERSIONNUMBER ="29"
CONFIG.ATTRIBUTE[1].NAME="Field1"
CONFIG.ATTRIBUTE[1].VALUE =""
CONFIG.ATTRIBUTE[2].NAME="Field2"
CONFIG.ATTRIBUTE[2].VALUE ="NO"

基本上具有Xpath =值格式。你可以使用python与XML库或XSLT和xsl模板实现这一点。
