使用minidom在xml文件中解析一个元素

Question

我正在试图获取字符串“W：_fdsw \ Projects \ HIL \ releases \ release_9_1_0 \ Config \ CDNG \ UX_EF_TSHIL \ UX_EF_TSHIL.CDP”并使用minidom将其保存在变量中

        <TOOL id="CONTROLDESKNG" xsi:type="tool">
        <TOOL-HOST xsi:type="unicode">tsp:QMUC633107:5018</TOOL-HOST>
        <TOOL-NAME xsi:type="unicode">CONTROLDESKNG</TOOL-NAME>
        <START-OPTION xsi:type="integer">0</START-OPTION>
        <START-PRIORITY xsi:type="integer">0</START-PRIORITY>
        <SETTINGS xsi:type="dynamicPropertySet">
            <PROPERTY format-rev="1" name="ExpName" propertyType="string" readonly="false" xsi:type="_property">
                <VALUE xsi:type="unicode">K53MU</VALUE>
            </PROPERTY>
            <PROPERTY format-rev="1" name="ModelDir" propertyType="uri" readonly="false" xsi:type="_property">
                <VALUE xsi:type="unicode">W:\_fdsw\Projects\HIL\releases\release_9_1_0\Config\CDNG\UX_EF_TSHIL\Variable Descriptions\UX_EF_TSHIL.sdf(#14)</VALUE>
            </PROPERTY>
            <PROPERTY format-rev="1" name="PrjFile" propertyType="uri" readonly="false" xsi:type="_property">
                <VALUE xsi:type="unicode">W:\_fdsw\Projects\HIL\releases\release_9_1_0\Config\CDNG\UX_EF_TSHIL\UX_EF_TSHIL.CDP</VALUE>
            </PROPERTY>
            <PROPERTY format-rev="1" name="RecordingFormat" propertyType="string" readonly="false" xsi:type="_property">
                <VALUE xsi:type="unicode">MDF</VALUE>
            </PROPERTY>
            <PROPERTY format-rev="1" name="ToolState" propertyType="string" readonly="false" xsi:type="_property">
                <VALUE xsi:type="unicode">Online</VALUE>
            </PROPERTY>
            <PROPERTY format-rev="1" name="VersionCDNG" propertyType="string" readonly="false" xsi:type="_property">
                <VALUE xsi:type="unicode">5.5</VALUE>
            </PROPERTY>
            <PROPERTY format-rev="1" name="VersionHILAPI" propertyType="string" readonly="false" xsi:type="_property">
                <VALUE xsi:type="unicode">2015-B</VALUE>
            </PROPERTY>
        </SETTINGS>
    </TOOL>

我的代码是：

xmldoc = minidom.parse('C:\Users\qxn5622\Desktop\EF10018\DEFAULT.tbc')
propertyList = xmldoc.getElementsByTagName('PROPERTY')
for prop in propertyList:
    if prop.attributes["name"].value == "ModelDir":
        myString = prop.getElementsByTagName("VALUE").value

我认为问题是我想要获得的元素没有任何孩子。有谁能够帮我？

这可能有所帮助

from xml.dom.minidom import parse
dom = parse('C:\Users\qxn5622\Desktop\EF10018\DEFAULT.tbc')

propertyList = dom.getElementsByTagName('PROPERTY')
for prop in propertyList:
    if prop.getAttribute('name') == "PrjFile":
        myString = prop.getElementsByTagName("VALUE")
        print myString[0].firstChild.nodeValue

输出：

W:\_fdsw\Projects\HIL\releases\release_9_1_0\Config\CDNG\UX_EF_TSHIL\UX_EF_TSHIL.CDP
