查询xpath中的整数(Query regarding integer in xpath)

查询xpath中的整数(Query regarding integer in xpath)

我们可以在我的xpath查询中添加整数，如“A / B / 123”。 如果没有，那么请你告诉我有没有办法把整数放在xpath中

Can we put integer in my xpath query like "A/B/123". If No then can you please tell me is there any way to put integers in xpath

最满意答案

XML元素名称的第一个字符仅限于以下集合

":" | [AZ] | "_" | [az] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF]

请参见http://www.w3.org/TR/REC-xml/#NT-NameStartChar 。 这不包括数字。

为什么不在标记中使用属性并在XPath查询中搜索该属性，例如

XML

<A> <B> <C id="123" /> </B> </A>

XPath的

A/B/C[@id="123"]

The first character of XML element names is restricted to the following set

":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF]

See http://www.w3.org/TR/REC-xml/#NT-NameStartChar. This does not include digits.

Why not use an attribute in your markup and search for that in your XPath query, eg

XML

<A> <B> <C id="123" /> </B> </A>

XPath

A/B/C[@id="123"]
