我有一个XML文件(实际上是一个xliff文件),其中一个节点有2个具有相同子结构的子节点(先验不知道,可能非常复杂并且每个<trans-unit>
都有变化)。我正在使用python和lxml库...示例:
<trans-unit id="tu4" xml:space="preserve">
<seg-source>
<mrk mid="0" mtype="seg">
<g id="1">...</g>
<g id="2">...</g>
<g id="3">...</g>
<bx id="7"/>...
</mrk>
<mrk mid="1" mtype="seg">...</mrk>
<mrk mid="2" mtype="seg">...
<ex id="7"/>
<g id="8"> FROM HERE </g>
</mrk>
</seg-source>
<target xml:lang="en">
<mrk mid="0" mtype="seg">
<g id="1">...</g>
<g id="2">...</g>
<g id="3">...</g>
<bx id="7"/>...
</mrk>
<mrk mid="1" mtype="seg">...</mrk>
<mrk mid="2" mtype="seg">...
<ex id="7"/>
<g id="8"> TO HERE </g>
</mrk>
</target>
</trans-unit>
如您所见,2个节点<seg-source>
和<target>
具有完全相同的子结构。我的目标是导航到<seg-source>
的每个节点,获取该节点的文本和尾部(我知道如何使用xpath执行此操作),翻译它们并最终(这就是我不喜欢的内容)。知道怎么做)分配到<target>
翻译中的相应节点......
换句话说......假设我得到了节点&#34;从这里&#34; ...我怎样才能得到节点&#34;到这里&#34;?
答案 0 :(得分:0)
如果您想要将它们配对,您只需将节点压缩在一起,这样就可以从每个节点中访问匹配的代码:
from lxml import etree
tree = etree.fromstring(x)
nodes = iter(tree.xpath("//*[self::seg-source or self::target]"))
for seq, tar in zip(nodes, nodes):
# each node will be the matching nodes from each seq-source and target
print(seq.xpath(".//*"))
print(tar.xpath(".//*"))
由于每个trans-unit
中只有两个,因此您可以使用nodes = iter(tree.xpath("//trans-unit/*"))
,因此内部节点的名称并不重要。
nodes = iter(tree.xpath("/trans-unit/*"))
for seq, tar in zip(nodes, nodes):
print(seq.xpath(".//*"))
print(tar.xpath(".//*"))
如果我们在您的示例上运行代码并打印每个id节点,您可以看到输出从每个节点获得一个:
In [2]: from lxml import etree
In [3]: tree = etree.fromstring(x)
In [4]: nodes = iter(tree.xpath("//trans-unit/*"))
In [5]: for seq, tar in zip(nodes, nodes):
...: print(seq.xpath(".//g[@id='8']/text()"))
...: print(tar.xpath(".//g[@id='8']/text()"))
...:
[' FROM HERE ']
[' TO HERE ']
每个节点都是来自trans-unit的每个子节点的对应节点:
In [7]: for seq, tar in zip(nodes, nodes):
...: print(seq.tag, tar.tag)
...: for n1, n2 in zip(seq.xpath(".//*"),tar.xpath(".//*")):
...: print(n1.tag, n2.tag)
...:
('seg-source', 'target')
('mrk', 'mrk')
('g', 'g')
('g', 'g')
('g', 'g')
('bx', 'bx')
('mrk', 'mrk')
('mrk', 'mrk')
('ex', 'ex')
('g', 'g')
