How to match all the /records/record/name having as sibling /records/record/record-type with the value "A"?

网友答案:

Found it:

/records/record/name[../record-type/text() = "A"]
网友答案:

You can also filter a parent element by its children :

/records/record[record-type[text()='A']]/name

网友答案:

Surprisingly, none of the answers to date on this old question provide the simplest XPath solution.

This simple XPath

/records/record[record-type = "A"]/name

selects

<name>svn</name>
<name>blog</name>

as requested.

网友答案:
/records/record[record-type='A']
