Question

我试图在我的xml中包含一个实体，但是，它似乎没有显示。我对XML非常陌生，所以如果我在研究中发现的不是最佳实践，那么我对改变是开放的。

要包含的XML

<resume>
    <personal_info>
        <birthdate>07/08/1988</birthdate>
    </personal_info>
    <jobs>
        <job>
            <company>Radio Shack</company>
            <title>Sales Representative</title>
            <startdate>01/01/2011</startdate>
            <enddate>02/02/2011</enddate>
            <duration>1.5yrs</duration>
            <sortdate>20110101</sortdate>
        </job>
        <job>
            <company>Radio Shack2</company>
            <title>Sales Representative</title>
            <startdate>01/01/2013</startdate>
            <enddate>02/02/2013</enddate>
            <duration>1.5yrs</duration>
            <sortdate>20130202</sortdate>
        </job>
    </jobs>
</resume>

包含XML

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE downloadWord SYSTEM "resume.dtd"[
<!ENTITY resume SYSTEM "resume.xml">
]>
<thing>
&resume;
</thing>

DTD

<!ELEMENT thing (resume)>
<!ELEMENT resume (personalinfo, jobs)>
<!ELEMENT personalinfo (birthdate)>
<!ELEMENT birthdate (#PCDATA)>
<!ELEMENT jobs (company,title,startdate,enddate,duration,sortdate)>
<!ELEMENT company (#PCDATA)>
<!ELEMENT title (#PCDATA)>
<!ELEMENT startdate (#PCDATA)>
<!ELEMENT enddate (#PCDATA)>
<!ELEMENT duration (#PCDATA)>
<!ELEMENT sortdate (#PCDATA)>

Answer 1

DOCTYPE之后的字必须是文档根元素（将downloadWord替换为thing）：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE thing SYSTEM "resume.dtd"[
    <!ENTITY resume SYSTEM "resume.xml">
]>
<thing>
    &resume;
</thing>

那应该包含文件（这将导致验证错误，因为文档与DTD不匹配。要修复DTD以使其与实例匹配（您可能希望执行相反的操作）：

第2行：将personalinfo更改为personal_info：

<!ELEMENT resume (personal_info, jobs)>

第5行：将jobs替换为job：

<!ELEMENT job (company,title,startdate,enddate,duration,sortdate)>

添加新行：

<!ELEMENT jobs (job+)>

这是验证上述文件的最终resume.dtd DTD：

<!ELEMENT thing (resume)>
<!ELEMENT resume (personal_info, jobs)>
<!ELEMENT personal_info (birthdate)>
<!ELEMENT birthdate (#PCDATA)>
<!ELEMENT jobs (job+)>
<!ELEMENT job (company,title,startdate,enddate,duration,sortdate)>
<!ELEMENT company (#PCDATA)>
<!ELEMENT title (#PCDATA)>
<!ELEMENT startdate (#PCDATA)>
<!ELEMENT enddate (#PCDATA)>
<!ELEMENT duration (#PCDATA)>
<!ELEMENT sortdate (#PCDATA)>

XML实体包括不显示
