摘取Mysql XML垃圾堆放场上的数据。
原标题:Extracting Data from Mysql XML dump with xml.dom.minidom

我向Sandql数据库出口到Sandml,现在,我要用小米,但我有麻烦地以我需要的形式获取内容。

摘要:我需要将<条码>标题分配给载于<条码>和>的案文;栏目名称=“news_title”>即标题和/column>。

摘录的 d认为:

<pma_xml_export version="1.0" >
    <database name="dbname">
        <!-- Table newsbox -->
        <table name="newsbox">
            <column name="news_id">1</column>
            <column name="news_title">This is the title</column>
            <column name="news_text">This is the news text</column>
            <column name="date">Thu, 28 Feb 2008 20:10:30 -0500</column>
            <column name="author">author</column>
            <column name="category">site_announcement</column>
        </table>
    </database>
</pma_xml_export>

我能够用以下文字提取案文,但并非按我需要的形式:

doc = parseString(document)

pmaexport = doc.getElementsByTagName("pma_xml_export")[0]
columns = pmaexport.getElementsByTagName("column")


for item in columns:
    name = item.getAttribute("name")
    text = item.firstChild.data.strip()
    print name, text

我需要的是,我可以把这些要素的案文内容分配到可以传递的变量,例如:

for item in columns:
    title = ???
    text = ???
    date = ???
    author = ???

如果db输出的形式是< entitled>Here s the Owner</ entitled> 我要举几个例子,但我仅能发现任何提及诸如<条码>和>;column name=“news_title”>这是标题和/column>。

最佳回答

这是自我使用<条码>xml.dom.minidom<>/条码>以来的一段时期,但这项工作应当有效。

columns = [c.firstChild.data for c in pmaexport.getElementsByTagName( column ) if c.getAttribute( name ) ==  news_title ]

此外,正如清单一样,我们理解!
