I have a xml file which I need to retrieve the node "DocIDAutoNumerator" value but I only need to take it if the filed "ActivityTime" contains the date of today (2021-08-11) lets say and if the node "DocumentTypeValue" equals 1319. I was trying for hours but can mange to retrieve it with what I did. This is what I did -

XPath

//Document[.//Field[Code[text()='DocumentTypeValue'] and Value[text()='1319']] and //ActivityTime[contains(text(),'2021-08-11')] ]//Fields[Field[Code="DocumentTypeValue"]]  /Field[Code="DocIDAutoNumerator"]/Value

XML

    <Document>
       <Labels>
          <Label>
             <Fields>
                <Field>
                   <Code>DocumentTypeValue</Code>
                   <Value>4008</Value>
                </Field>
                <Field>
                   <Code>DocIDAutoNumerator</Code>
                   <Value>123121</Value>
                </Field>
             </Fields>
          </Label>

      <ActivityTime>2021-08-11 </ActivityTime>
    </Document>
    <Document>
       <Labels>
          <Label>
             <Fields>
                <Field>
                   <Code>DocumentTypeValue</Code>
                   <Value>1319</Value>

                <Field>
                   <Code>DocIDAutoNumerator</Code>
                   <Value>21321</Value>

This (admittedly convoluted) xpath expression

//Document[contains(.//ActivityTime,"2021-08-11")]  \
[.//Field[.//Code[.="DocumentTypeValue"]][.//Value[.="4008"]]]   \
//Field[./Code[.="DocIDAutoNumerator"]]/Value

should output, given your example xml

123121

This XPath,

/root/Document[normalize-space(ActivityTime)='2021-08-11']
     //Fields[Field/Code='DocumentTypeValue']
      /Field[Code='DocIDAutoNumerator']/Value/text()

selects the text of the targeted Value,

123121

as requested.

Explanation

  1. Select Document based on the given ActivityTime value.

    • Use normalize-space() to eliminate variances to do, in this case, trailing whitespace.

  2. From there, select Fields based on the given Field/Code value.

  3. From there, select the Field based on the given Code` value.

  4. Select that Field element's Value child's text.

Update:

To also add that the Field with a DocumentTypeValue Code must have a 4008 Value:

/root/Document[normalize-space(ActivityTime)='2021-08-11']
        //Fields[Field[Code='DocumentTypeValue'][Value='4008']]
         /Field[Code='DocIDAutoNumerator']/Value/text()
