使用 XPATH 1.0 和包含特定文本的 xmlstarlet 选择节点

Question

从下面的XML开始为：

<?xml version="1.0" encoding="UTF-8"?><searchRetrieveResponse>
<version>1.2</version>
<numberOfRecords>1</numberOfRecords>
<records>
<record>
<recordSchema>marcxml</recordSchema>
<recordPacking>xml</recordPacking>
<recordData>
<record>
<leader>01448cam a2200445Ia 4500</leader>
<controlfield tag="001">9910650701858</controlfield>
<controlfield tag="005">20181227054218.2</controlfield>
<controlfield tag="008">930525s1941    nyu      b    001 0 eng d</controlfield>
<datafield tag="035" ind1=" " ind2=" ">
<subfield code="a">(OCoLC)28157672</subfield>
</datafield>
<datafield tag="035" ind1=" " ind2=" ">
<subfield code="a">(OCoLC)ocm28157672</subfield>
</datafield>
<datafield tag="035" ind1=" " ind2=" ">
<subfield code="a">(EXLNZ-01ALLIANCE_NETWORK)99153881770001451</subfield>
</datafield>
<datafield tag="040" ind1=" " ind2=" ">
<subfield code="a">UTS</subfield>
<subfield code="b">eng</subfield>
<subfield code="c">UTS</subfield>

我只需要使用 xmlstarlet (XPATH 1.0( 选择包含(EXLNZ-01ALLIANCE_NETWORK( 的/searchRetrieveResponse/records/record/recordData/record/datafield[@tag="035"]/subfield[@code="a"]的文本节点，因此所需的输出是 (EXLNZ-01ALLIANCE_NETWORK 99153881770001451

我已经尝试了许多xmlstarlet sel -T -t -m '/searchRetrieveResponse/records/record/recordData/record/datafield[@tag="035"]/subfield[@code="a"][text()[contains(.,'ALLIANCE_NETWORK')]]' -v '.'变体，但我不断返回所有 035/子字段[@code="a"]，而不仅仅是我想要的那个。我做错了什么？谢谢

Answer 1

想通了 - 包含过滤器设置不正确。我发布只是因为我发现匹配节点很尴尬。

xmlstarlet sel -T -t -m '/searchRetrieveResponse/records/record/recordData/record/datafield[@tag="035"]/subfield[@code="a"][contains(text(), "ALLIANCE_NETWORK")]' -v '.'
