[英]Python version 2.7: XML ElementTree: How to iterate through certain elements of a child element in order to find a match
[英]How to iterate through multiple child nodes of xml item using python 2.7
我正在尝试以以下形式解析来自USPTO的结构不完美的XML数据:
<parent>
<child>
<child-text>text
<child-text>more text</child-text>
<child-text>more text</child-text>
</child-text>
</child>
</parent>
我正在尝试捕获子文本节点的所有文本。 但是如您所见,第一个子文本标签直到所有其余标签都完成后才关闭。 以下摘录是一个示例:
<claims id="claims">
<claim id="CLM-00001" num="00001">
<claim-text>1. An all-solid-state electrochromic device comprising:
<claim-text>a transparent base material; and</claim-text>
<claim-text>an electrochromic multilayer-stack structure formed on the transparent base material, the electrochromic multilayer-stack structure comprising:
<claim-text>a first transparent-conductive film;</claim-text>
<claim-text>an ion-storage layer formed on the first transparent-conductive film;</claim-text>
<claim-text>a solid-electrolyte layer formed on the ion-storage layer; and</claim-text>
<claim-text>an electrochromic layer formed on the solid-electrolyte layer, the electrochromic layer comprising a reflection-controllable electrochromic layer comprising an antimony-based alloy comprising Sb<sub>x</sub>CoLi<sub>y </sub>in which 0.5≦x≦10, and 0.1≦y≦10.</claim-text>
</claim-text>
</claim-text>
</claim>
<claim id="CLM-00002" num="00002">
<claim-text>2. The all-solid-state electrochromic device according to <claim-ref idref="CLM-00001">claim 1</claim-ref>, wherein 3≦x≦5 and 0.1≦y≦3.</claim-text>
</claim>
</claims>
我当前的方法仅捕获第一个标签的内容,而不能充分捕获子元素的内容(例如在上面的示例中):
claims = self.xml.claim
for i, claim in enumerate(claims):
data = {}
data['text'] = claim.contents_of('claim_text', as_string=True, upper=False)
尽管结构不一致,如何遍历所有<claim-text>
标签和<claim-ref>
子标签?
我对xml文档有类似的问题。 我所做的是
<xml_document>[<xml_document>.find("<claim-text>")+len(<claim-text>):<xml_document>.find("</claim-text>")]
然后使用if语句删除xml标签内容中的所有多余标签
if content contains [<\d>] then remove them by finding their indexes
对于每次迭代,都通过索引删除xml_document的解析部分。
