我有这个xml文档。我试图将此处显示的数据组1-7放入数据类别。当使用Xpath时,我通常可以过滤到我需要的位置,但是当我访问Con1时,似乎只给了我那组孩子,它给了我同一级别的“dict”
<dict>
<key>Tester</key>
<dict>
<key>Con1</key>
<dict>
<key>KeySet</key>
<dict>
<key>B52:B53:B54</key>
<array>
<dict>
<key>0:0:0</key>
<dict>
<key>Data</key>
<array>
<string>1</string>
<string>2</string>
<string>3</string>
<string>4</string>
<string>5</string>
<string>6</string>
<string>7</string>
</array>
</dict>
</dict>
<dict>
<key>15:15:3</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>7:15:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>7:15:1</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
</array>
</dict>
</dict>
<key>Con2</key>
<dict>
<key>KeySet</key>
<dict>
<key>B52:B53:B54</key>
<array>
<dict>
<key>0:0:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>0:16:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>0:48:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
</array>
</dict>
</dict>
<key>Con3</key>
<dict>
<key>KeySet</key>
<dict>
<key>B52:B53:B54</key>
<array>
<dict>
<key>0:0:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
</array>
</dict>
</dict>
</dict>
所以,如果我写:
myPath = '//dict[key/text()="Tester"]/dict[key/text()="Con1"][1]'
x = tree.xpath(myPath)
etree.tostring(x, pretty_print=True)
我会得到:
<dict>
<key>Con1</key>
<dict>
<key>KeySet</key>
<dict>
<key>B52:B53:B54</key>
<array>
<dict>
<key>0:0:0</key>
<dict>
<key>Data</key>
<array>
<string>1</string>
<string>2</string>
<string>3</string>
<string>4</string>
<string>5</string>
<string>6</string>
<string>7</string>
</array>
</dict>
</dict>
<dict>
<key>15:15:3</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>7:15:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>7:15:1</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
</array>
</dict>
</dict>
<key>Con2</key>
<dict>
<key>KeySet</key>
<dict>
<key>B52:B53:B54</key>
<array>
<dict>
<key>0:0:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>0:16:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>0:48:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
</array>
</dict>
</dict>
<key>Con3</key>
<dict>
<key>KeySet</key>
<dict>
<key>B52:B53:B54</key>
<array>
<dict>
<key>0:0:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
</array>
</dict>
</dict>
我希望只获得第一个连接集,以便我可以正确地添加我的数据。因此,运行该组代码时的理想输出如下所示:
<dict>
<key>Con1</key>
<dict>
<key>KeySet</key>
<dict>
<key>B52:B53:B54</key>
<array>
<dict>
<key>0:0:0</key>
<dict>
<key>Data</key>
<array>
<string>1</string>
<string>2</string>
<string>3</string>
<string>4</string>
<string>5</string>
<string>6</string>
<string>7</string>
</array>
</dict>
</dict>
<dict>
<key>15:15:3</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>7:15:0</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
<dict>
<key>7:15:1</key>
<dict>
<key>Data</key>
<array/>
</dict>
</dict>
</array>
</dict>
</dict>
我在这里做错了什么?
对于Andersson的回复,我将使用此代码编辑源代码。它确实有效,但由于上述问题,在确定应该放置的正确级别时遇到问题。
for parent in tree.xpath(myPath)
parent.insert(1, data)
答案 0 :(得分:0)
经过大量调试后我发现如果我添加&#34; / dict&#34;打电话我可以分开我的部分并使用[#]
访问它们所以不要这样:
myPath = '//dict[key/text()="Tester"]/dict[key/text()="Con1"][1]'
使用此
myPath = '//dict[key/text()="Tester"]/dict[key/text()="Con1"]/dict[1]'
